This guy hates Nikola Tesla and wants to debunk his work

Medialibraryinfo@gmail.com +1-313-651-5349 Media Library Text 313-777-3031


After reading this article I just wondered what did Tesla actually get these types of awards for,


 what was all those patents he filed all about,
of course you know this article you are about to read doesn't mention one thing that he actually did he just used his form to criticize one of the most important scientists of our time. But I couldn't find anything about Edison who wasn't even in the inventor who created nothing, and was a thief.
So while you're reading how he didn't create the fluorescent lightbulb, he did create a lightbulb keep that in mind as you read his criticism. Nikola Tesla greatly improved on other people's inventions were they failed or had been trying for years, he simply did it. Let's read what this hater has to say.

Debunking the Tesla Myth:


False facts about Tesla giving him more credit than he deserves.
In today's world of infotainment, web pages and documentaries have popped up proclaiming Nikola (Nicola) Tesla of being the inventor of practically everything. The more sites that pop up, the more reinforced false facts become. This is wrong because it denies respect for the true inventors of the technology, as well as over-simplifies history. If you love Tesla, prepare to get seriously upset as you realize you've been led on by mainstream media. The truth hurts but I hope your inspired to get deeper into the real history of this amazing era of early electricity.
Nikola Tesla: dreamer, showman, NYC socialite and vain douchebag. His metaphysical speeches and grand demonstrations captivated the newspapers and wealthy but his actual contributions to engineering are limited. His narcissistic behavior leads him to not credit his assistants or co-workers for helping. He even fails to thank people on his "side" like Ben Lamme and Shallenberger at Westinghouse who took his useless induction motor prototype and redesigned it into something worth talking about (and selling).Didn't your mother tell you not to believe everything you read on the internet? So before you go back to the Tesla mania pages we suggest you go to a library and dig up some facts from books and patent applications, just as real historians have.
Tesla - Center of Media Attention Since the 1880s:
Tesla's position as the god of pop science and fantasy is not just the product of the internet. As it turns out Tesla lived in Manhattan and was always ready to give newspapers his opinion on matters. Whereas other inventors and engineers were busy working in far away places like Pittsburgh and Schenectady (actually getting work done). Tesla loved to talk and dine with New York's elite. He used his position in the heart of mainstream media at NYC and worked, and still works well for him. The press were recently inspired by the the huge changes Thomas Edison had made for the world and everyone was looking to find the next inventor-god to give us hope, Tesla was one of the people they glorified. Oddly enough this eloquent speaking "blowhard" continues to dazzle audiences 130 years later despite modern science and math which shows he was wrong about much of what he said, and most engineers and scientists of the day were disappointed that he did not achieve the exciting ideas he spoke about. Lets look at the myths that media has created over the years below.

This three phase generator and system by Dobrovolsky conclusively ended the War of Currents 1891.

Myth 1:

Tesla invented polyphase AC power, or some say AC power in general: FALSE.
First there was a hand-cranked AC generator developed by Hippolyte Pixii in 1832. Single phase AC power was being used more in Europe by many inventors in the early 1880s. As early as the late 1870's Germany had developed a crude 2 phase AC generator. Galileo Ferraris, a scientist in Italy started talking openly about polyphase AC in 1885, one year later Tesla approached investors with his version of an AC system but did not succeed in generating interest. Ferraris also inspired Thomson at Thomson-Houston and engineers at Westinghouse to investigate the system however there was little confidence among investors in AC power at the time.
From a world perspective there were many people working on AC systems over the next few years. August Haselwander and C.S. Bradley(a former Edison employee) created the first 3 phase AC generators(1887). Mikhail Dolivo-Dobrovolsky built the first full 3 phase AC generation and distribution system in the 1888-1891 period. Tesla to his credit was able to inspire Westinghouse to jump into AC, but very quickly Tesla's two-phase system was made obsolete by three phase systems which could more efficiently send power farther. The fact is that like today there are many people working on cutting edge technology and if Tesla had not gotten Westinghouse's attention in 1888, Westinghouse would have bought patents from others. Thomson was close to innovation on the AC system as well, and the world would be no different without Tesla, it may have just taken another year for polyphase to get adopted by Westinghouse or Elihu Thomson's company. 

Myth 2:

Tesla invented the transformer: FALSE.
The Ganz company in Budapest was the first to create and use transformers in AC systems in the late 1870s.Tesla was still in school then and hadn't even began his first job in the field of telephony. His first job was in Budapest in 1880, this is where he possibly observed/stole ideas, and was convinced by the Hungarians that AC was viable and worth pursuing while the West was still 5 years behind.
William Stanley invented the first modern transformer in 1885. His design was based on the Gaulard and Gibbs design. Gaulard had used his transformer in the 1884 Lanzo to Turin AC power demonstration. Also credit goes to the Z.B.D Transformer in Hungary The Z.B.D. Transformer proved to be extremely inefficient and problematic so Stanley designed his own. This is backed up by information at the Smithsonian and IEEE. The Edison Tech Center has published a lot of material on William Stanley sourcing from the Great Barrington Historical Society, the Berkshire Museum and historian Tom Blalock. It was in 1885 that Tesla actually joined the minority of inventors working with AC in trying to pitch his system. There is no proof that Tesla had any mature AC systems designed and ready before then. (Tesla claims to have envisioned his own full AC system in 1882 but there are no written documents of any kind to prove this)
Károly Zipernowsky, Miksa Déri and Ottó Bláthy invented the first transformer. William Stanley perfected the transformer in monocyclic and 3 phase AC systems. Tesla and his Westinghouse co-worker Oliver Shallenberger developed the transformer to work work with his 2 phase AC systems. Due to Tesla's egomania you will never hear him thank Shallenberger or cohorts. It was clear he was not a team player and it is no surprise Westinghouse didn't want him around for long. His technical contributions were appreciated and Tesla was generously paid by Westinghouse for his work. Shallenberger and others at Westinghouse benefited from Steinmetz's mathematics and were able to create a 3 phase system later on to replace Tesla's system.
Stanley's Transformer
Above: Stanley's landmark transformer from 1885, the prototypes are located in Pittsfield, MA and another is on display at the Smithsonian, I've seen them both.

Myth 3:

Tesla invented the induction coil: FALSE. Absolutely false...
Induction was discovered by Michael Faraday, and the induction coil was invented by Nicholas Callan in 1836, long before Tesla was born.

Myth 4:

Tesla invented the loudspeaker: FALSE.
The loudspeaker as we know it was invented by C.W. Rice and Edward Kellogg with a working prototype in 1921, and patent in 1925. Decades before this final success, Werner Von Siemens had toyed with the idea of a magnetically controlled speaker while Tesla was in grade school.

Myth 5:

Tesla invented radar in 1917: FALSE.
This one is a real can of worms, radar was made possible due to the work of Christian Hulsmeyer (German)1903, Lee De Forest 1918, Edwin Armstrong 1918, Ernst Alexanderson, Marconi, Albert Hull, Edward Victor Appleton, and Russians who developed a radar system to detect German planes in 1934. Sir Robert Watson-Watt demonstrated the first HF radar system in 1935 which operated at 6 MHz and had a range of 8 miles. There are many books on this subject.

Myth 6:

Tesla invented the fluorescent lamp: FALSE.
Alexandre E. Becquerel first examined the phenomena of fluorescence in 1857. Some say Edison invented the lamps. Others say George Inman developed the modern fluorescent lamp in 1934. It is tough to say who was first since there was a legal dispute. There is a possibility that the German Edmund Germer preceded both of them. Many people worked on the concept, Inman deserve the credit for building the first successful and practical design. Even if Tesla had played with the theories, he was not alone at any time, and didn't do squat compared to others who had actually worked out the difficulties into a real working product. Daniel McFarlan Moore developed the Moore Tube which was the first commercial ancestor of the fluorescent lamp.
Above graphic: just some of the inventors of the standard fluorescent light. Missing from this graphic is Thomas Edison and Nikola Tesla who both contributed but were not key contributors. Tesla was more important in promotion and development of the of the induction lamp which also used fluorescence. Johann Wilhelm Hittorf, J. J. Thomson, Nikola Tesla, Peter Cooper Hewitt and John Anderson were the top 5 contributors making the induction lamp possible.

Myth 7:

Tesla invented microwave transmitters: FALSE.
Albert W. Hull invented a type of magnetron which lead to many inventions, including today's microwave oven, the microwave communications link, and radar. You can dig deeper on this and find many early pioneers even before Albert Hull. The Edison Tech Center and Schenectady Museum have a lot of material on this era of history.

Myth 8:

The 1895 Niagara Falls Hydropower Plant was the first commercial AC hydro power plant: FALSE.
This is absolutely false. AC power sites were developed first in Europe from 1878-1885. After 1885 Westinghouse hired Stanley, Oliver Shallenberger, Benjamin Lamme, and others to build AC power systems in North America. Tesla didn't join Westinghouse until 1888. See our list of early AC power sites here.
The Redlands Power Plant build in 1893 was the first 3 phase AC power plant built for commercial purposes in North America. Elihu Thomson, Almirian Decker and Dr. ,Louis Bell worked together to design this site a few years before in Lynn, Massachusetts. Dobrovolsky had build the first full hydroelectric three phase AC power system at Frankfurt in 1891. Also, at the time Charles P. Steinmetz was the only one to understand the concept of hysteresis and related physics concepts that helped run the AC generator. Steinmetz was a humble man, and like many technical men, loved teaching and connecting to other humans just as much as the technology. People with a teaching spirit have often let others take the fame and patents. Fame and business success are the focus of only a percentage of engineers. The love of the craft is common among all of them.

Myth 9:

Tesla was the underdog who did not promote himself: FALSE.

If you begin to read at all about history of technology at the time you will find that inventions and ideas spread like wildfire from as far east as Hungary and Moscow, to the U.S. For someone like Edison or Tesla it was important to keep up the show and wizardry to captivate the public. And they both did that very well. In the ruthlessly competitive environment of New York City the game was, (and still is) about fame/success at any cost. Tesla, when living on Fifth Avenue was at the epicenter of this pressure. Tesla was business natured, he understood he had to relentlessly promote himself to become like the more successful Edison. Most inventors at the time did not have the relentless need for attention that both of them had.

Myth 10:

Back in the late 1800's the conflict for AC vs. DC was Tesla vs. Edison, or Westinghouse vs. General Electric: FALSE.

General Electric was formed in 1892 and by that time Thomas Edison had a minimal role in the workings of the company. While Edison promoted DC power from his home down in New Jersey/New York City area, Elihu Thomson, William Stanley, and C.P. Steinmetz promoted AC as the future. The company was not "for DC". Tesla and Edison did not get along, that's true... but of course! Popular media likes to promote the AC vs. DC conflict in a simple easy-to-digest package simply because all the Mass Communication majors and journalists have been taught that the public loves to watch and read about conflict. One page reads: "Edison also hated Tesla because Tesla invented..." and so on, the quote highlights once again the conflict aspect. If conflict and drama is your focus of interest, than study the World Wrestling Federation, not engineering.
More Controversy: Who invented the polyphase electric motor?:
Tesla was first to patent the 3 phase AC motor in the USA 1888, but read on: Galileo Ferraris had come up with the same design months before in Italy, and Ferraris had talked about the motor as early as 1885. Ferraris was a university professor with no interest in making money from the invention. We know that Tesla was extremely intelligent and was able to memorize entire books after reading them. It is entirely possible that Tesla had obtained a copy of Ferraris's publication to the Royal Academy of Sciences in Turin and was able to understand Ferraris's design. He would be able to copy and clarify the design on paper and submit that to the patent office with the help of Tesla's well-paid team of lawyers. If this was the case than it is just another case of how businessmen with their well paid lawyers have crushed an academic person's claim on being the first. History was almost rewritten here but documents have proven Galileo's claim. Tesla had no evidence to support his self-made claim that he envisioned the motor in 1882. In addition to this Mr. Ferraris had a track record of being an innovator in the greatest events of European AC development in the early 1880's. Tesla had limited experience in AC and was not picked up by Westinghouse until 1888, after his claim of inventing a poly phase motor. Read more on the trial here.
Free Electric Power:
Many Tesla fans claim a conspiracy theory stopped Tesla from making "free" electric power distribution wirelessly. First of all infrastructure is still needed and there is no way power will ever be "free". Wireless power distribution is not practical since it is extremely inefficient with huge losses over even a short distance. The final killer of Tesla's idea is the enormous danger of wireless power transmission for wildlife (birds) and damage to humans. Given the big debate on danger of cellphones to humans, and cellphones contain very low power levels, you can only imagine the danger of high powered wireless transmission.
Tesla vs. Edison - An attractive human story, but this isn't engineering.
Tesla left Thomas Edison's company frustrated and short changed. This is a popular story, but Tesla wasn't the only one who left Edison the same way.
Edison the Stubborn:
As the Tesla popular myth states: Tesla had approached Edison with the idea of trying AC development, and Tesla was the lone visionary, however Edison scoffed and said AC would never amount to anything. The truth is he wasn't alone. Others approached Edison and got the same results. C. S. Bradley had worked for Edison, he was convinced about AC's future, he left and invented the three-phase generator in 1887. Otto Blathy who invented the ZBD Transformer in Hungary came on a business trip to meet Edison in 1886. He tried to sell his patent to Edison, again, Edison scoffed at him. This was clearly a poor business decision because by this point Westinghouse had already built and demonstrated a working AC system at Great Barrington, Mass. Elihu Thomson of Thomson-Houston in Massachusetts was already trying to build his own transformer.

Electrocuting Elephants:

Another element in the Tesla vs. Edison debate which Tesla fanatics use to energize support for their "cause" is the electrocution of Topsy the elephant in 1903. Thomas Edison or his PR team, working independently of General Electric wanted to show the dangers of AC power by killing this innocent animal. Tesla is unlikely to have done the same to his credit, but most people in the population at the time had little regard for the fair treatment of animals. It is unlikely Edison stood out from other innovators who used animals to test medical treatments or conduct painful experiments. It was clearly a dark time for animals in industry. In 1903 General Electric had already been making revolutionary new AC power systems for 18 years and had some of the world's best engineers working on AC. Tesla fanatics are more known for their passion than their "historian" side, they fail to have the slightest understanding of the business atmosphere at the time or the wealth of OTHER great minds working on AC. While Edison was living in the past in 1903 promoting DC, the company he created which had led to the formation of General Electric (1892) was already a leader in AC power. The board of directors cast off Edison as unable to work in a team and a nut just as Tesla was cast off by Westinghouse as "unpredictable" and a nut who would sink the company financially with non-practical pursuits.
Edison and Tesla were independent inventors and had a lot in common. Contrary to the garbage that Tesla scholar tell you Thomas Edison actually stood up for Tesla at times. Edison used his influence to stop a damaging article about Tesla from getting published as he knew of Tesla's insecure personality. Edison feared that the article would send Tesla off the deep end into depression and that it would hurt his work. Edison actually encouraged Tesla at times and hoped Tesla could solve current problems including the design of a better x-ray. Edison respected Tesla's work on high frequency power and like many people of the day hoped that Tesla would deliver on breakthroughs which he promised.Back to Topsy the elephant: So who cares if Edison the nut was still promoting DC in 1903? Siemens-Halske, General Electric, Oerlikon, Westinghouse had already moved on into an AC world. There was no War of Currents in 1903. That war had ended in 1891.
Tesla was no "lone visionary" of AC power, he was simply smart enough to keep his eye on great developments of AC in Europe during the early-mid 1880s. He was one of a small group (the minority) of engineers working on AC in America in the mid 1880s. Tesla's first opportunity to work for a real company on AC power came after he "stole" or simultaneously invented the polyphase electric motor in 1888. At a public presentation Elihu Thomson and Westinghouse both thought that Tesla had potential. Thomson (later became GE) offered him a lower position to start. Tesla's ego lead him to decline the opportunity. Lucky for him later on Westinghouse offered him a position with his already established team of engineers working on AC. Westinghouse then got control of Tesla's induction motor patent which helped make them hundreds of millions of dollars. When the induction motor patent was contested in 1905 Westinghouse put it's best lawyers to work defending this cash maker. Let the induction motor fall into public domain and make Tesla loose credibility? The corporate might of Westinghouse would never let this happen!

Conclusion:

I could go on listing all of the false attributions and conspiracy theories regarding Tesla, but this would be a waste of time. The important thing is painting a true picture of ALL the wonderful and amazing personalities of technology in our history. Nikola Tesla was an inventor, and did share a love of engineering and science. And for this he deserves to be honored, but don't fall for the populist rhetoric. I'd recommend visiting the Deutsches Museum in Munich where many of the original first motors and dynamos are on display with accurate listings of attributions.

AC Power History

This article inspires controversy:
2015: Interestingly enough one of the largest sources of exaggerated Tesla history in the last few years was a cartoonist (Mr. Inman) who runs the website "The Oatmeal". A cartoonist (a guy with no engineering, legal or historian background) born in 1982 on the wrong side of the continent felt the liberty of making passionate statements about New York's electrical history based on crap he read on the internet. After a Forbes article by Alex Knapp about the myths of Tesla inspired by this Edison Tech Center article came out, the cartoonist attacks Knapp in the arrogant and cynical style typically demonstrated by the worst of US-born Millennials. Mr. Inman, like many comedians seems to be fundamentally unhappy and finds an outlet through humor. Oddly enough his behavior is similar to Tesla's in that he reacts in a nasty fashion if someone challenges his ideas, even when they mean well.

So after reading what he had to say about Nikola Tesla let's tell the truth. They were afraid of Nikola Tesla, even the government kept a close watch on Tesla she was the only inventor where the FBI took his patents for investigation after his death, and today some of his patents are heavily redacted. Of course he did things for other inventors that are just recorded, like when she's quit his job with Edison because Edison refuse to pay him after fixing his Motors that's no other Engineers or Adventures could fix. Then on top of that Edison tips some of Nikola Tesla's work and Designs he showed him. You have to remember Engineers are schools and educated for years there in a nice little box which to them they can't get out. Then comes in adventure who thinks outside the box. And is he cheating things that no one knows how in the world someone not even screwed as they are could do. What we're trying to say is that they underestimated a person because of a degree you had a achieved and a school. I'm sorry but a degree means nothing without accomplishments, this means that if you went to school for 7 years and got a degree for accomplishing your education. And did nothing else with that education what was it all for. Your time would been better served if you use that 7 years to create something for the future of our planet. I do recognize that most Engineers after receiving their degree never get recognized for some of their achievements so did Nikolai Tesla. If we're all working for bettering this world then what's the point it's just a piece of paper saying that someone recognize what you have done which is nice. The greater achievement is when you give people a green energy which can save a whole planet from the destructions there destined to go down. And still they won't use his Wireless technology and less it's plugged into their systems to make money.

So let's talk about this Wireless Systems since we wrote about it in previous papers. I was told that if electricity is Flowing down a wire oh, and the magnetic flux that's coming off of that wire and sheets is something that was lost. Remember when you have electricity you also has magnetic flux, so if this is a loss why can't we use it see picture below
But he said if you use this flux you're also using up the electricity this flowing Down The Wire. So what Nikolai Tesla achieve with his Wireless invention was doing the same.
I see not it's the reason why I wrote the paper on the flux capacitor. It was trying to show you that magnetic flux and electrical electricity can be used separately without interfering with one another. But as this radio repair person was trying to explain to me it's please stay in your little box don't go outside or even peek. The scientist and the engineers have already looked into this and they can't find any other explanation that you're using up their power and it's not a loss at all. I was thinking on this so if it's not a loss why aren't they using it to lower your the electricity bill.
I'm just in this Nikola Tesla is the father of radio, and the Supreme Court rude so. For those who do not want to give Nikolai Tesla his credit stay in your box, is exactly where we want you anyway. At least you won't interfere with real scientist work and achievements. For the rest of you that has the imagination and the guts to Step Beyond the rims of impossible, then look at this picture and figure it out
There's nothing else to say, but I will make a less comment the flux capacitor is in the diagram above, it could be as real or fictional as your imagination will allow it to be. But if you see the real life accomplishments of one person who took the diagrams of Nikola Tesla wireless energy to name it specifically and achieved a radio that use no external power but with comes out of the air itself. It's time you start to use it in other ways

Origami-Style Solar panels

Medialibraryinfo@gmail.com +1-313-651-5349 Media Library Text 313-777-3031


It's about time that they started using their creativity imagination to go along with those brains, here in Media Library we look forward to project like this. But it seems to be fine and few in between, because most people's imaginations don't expand out of the Realms of possibility. They always play it safe therefore they do not really create any sane extraordinary but this is an exception.
Solar Power, Origami-Style

As a high school student at a study program in Japan, Brian Trease would fold wrappers from fast-food cheeseburgers into cranes. He loved discovering different origami techniques in library books.
Today, Trease, a mechanical engineer at NASA’s Jet Propulsion Laboratory in Pasadena, California, thinks about how the principles of origami could be used for space-bound devices.
"This is a unique crossover of art and culture and technology," he said.
Trease partnered with researchers at Brigham Young University in Provo, Utah, to pursue the idea that spacecraft components could be built effectively by implementing origami folds. Shannon Zirbel, a doctoral student at BYU, spent two summers at JPL working on these ideas, supported by the NASA Technology Research Fellowship, with Trease as her research collaborator.
Researchers say origami could be useful one day in utilizing space solar power for Earth-based purposes. Imagine an orbiting power plant that wirelessly beams power down to Earth using microwaves. Sending the solar arrays up to space would be easy, Trease said, because they could all be folded and packed into a single rocket launch, with "no astronaut assembly required."
Panels used in space missions already incorporate simple folds, collapsing like a fan or an accordion. But Trease and colleagues are interested in using more intricate folds that simplify the overall mechanical structure and make for easier deployment.
Last year, Zirbel and Trease collaborated with origami expert Robert Lang and BYU professor Larry Howell to develop a solar array that folds up to be 8.9 feet (2.7 meters) in diameter. Unfold it, and you’ve got a structure 82 feet (25 meters) across. Their 1/20th-scale tabletop prototype expands to a deployed diameter of 4.1 feet (1.25 meters).
One technique that has been used for an origami-inspired solar array is called a Miura fold. This well-known origami fold was invented by Japanese astrophysicist Koryo Miura. When you open the structure, it appears to be divided evenly into a checkerboard of parallelograms.
With this particular fold, there’s only one way to open or close it: Pull on one corner and -- voila -- the whole thing is open with minimal effort. The mechanical structure of a device that folds this way is greatly simplified because only one input is required to deploy it.
Miura intended this fold for solar arrays, and in 1995 a solar panel with this design was unfolded on the Space Flyer Unit, a Japanese satellite. Despite this test, the technology is still in its early stages. But now, with an emphasis on small satellites and large structures, Trease says arrays inspired by this fold could see renewed usefulness.
"The fact that we're going both bigger and smaller may open up domains where it may be relevant again," Trease said.
The fold that Trease and colleagues used is not a Miura fold, but rather a combination of different folds. Trease's prototype looks like a blooming flower that expands into a large flat circular surface.
Trease envisions that foldable solar arrays could be used in conjunction with small satellites called CubeSats. And he says the origami concept could be used in antennas as well. It could be especially appropriate for spacecraft applications where it’s beneficial to deploy an object radially -- that is, from the center, outward in all directions. 
Origami was originally intended for folding paper, which has almost no thickness, so Trease and colleagues had to be creative when working with the bulkier materials needed for solar panels.
"You have to rethink a lot of that design in order to accommodate the thickness that starts to accumulate with each bend," he said.
Origami has been the subject of serious mathematical analysis only within the last 40 years, Trease said. There is growing interest in integrating the concepts of origami with modern technologies.
"You think of it as ancient art, but people are still inventing new things, enabled by mathematical tools," Trease said.

How to Build a Post and Beam Pavilion

Tailors in idea to save you on cement and still get the beauty that you're looking for

Does it seem like whenever you want to spend your day off outside, the weather foils your plans? Rain and hot sun can compress the already too short summer into only a few nice days. Expand your summertime and beat the elements by building this pavilion.

This project is made from cedar posts and dimensional lumber placed over a timber, concrete and patio stone base. It’s a challenge to build, but if you’ve built a deck, you can handle this. The pavilion will take you about two full weekends to build. Beauty doesn’t come cheap, though; expect to pay about $1500 for everything with a bit more for your personal landscaping touches.

Site Details

The pavilion’s patio base is easier to build if you have a level site. Uneven sites will have to be built up on the low side with extra landscape timbers.
To construct the patio, you’ll have to remote the turf with a sod cutter or shovel, then do a bit of digging. Our site has clay soil, which doesn’t drain well, so we added a few inches of sand beneath the timbers to drain away excess moisture. If your soil drains well, you can just dig to the thickness of the timbers and pour the 3/4-in. concrete base between the timbers, right over the undisturbed soil.

Getting Started

After you choose a site, pound stakes into the ground 11 ft. apart to establish your digging area. To make sure your staked area is square, just measure the diagonals. They must be equal to have a square perimeter. Stakes and string always seem to get in the way, so mark the turf with spray marking paint, which is available at hardware stores.
Dig out the turf to a level depth of 5-1/2 in. Cut timbers to the dimensions in the Materials List. (We used an electric chain saw, but a circular saw followed be a handsaw will do just fine.) Then spike them together at the corners. Tip: It’s best to stand on the timber you’re driving the spike into. It keeps the timbers from moving each time the sledge meets the spike. Spike the outside perimeter together first, then the inner as shown in Photo 2. After the timbers are joined, square the outside frame (remember, the diagonal measurements must be equal), then the inside frame. To make sure all the timbers are level and the inner frame is level with the outer frame, set a 4 ft. level along each timber. A bit of soil placed under the low sections will level them.
Before continuing, make sure the inside frame is 24-1/4 in. inside the outer frame on each side. Tamp a bit of soil around the timbers to hold them in place. You can also drive some wood stakes along the outside of each timber frame to keep it in position while you pour concrete. Now’s the time to prepare the pier forms for each corner as shown in the Figure A, so they’re ready when you pour the concrete.

Pavilion 01


Lay out an 11-ft. square area with marking paint. The area will be a bit larger than the patio to allow some elbow room to spike the timbers. Dig out the turf with a shovel or sod cutter to a depth of 5-1/2 in. If you have a low spot on any side, you may need extra timbers to level the area.
Pavilion 02
Connect the timbers with 12-in. spike nails at each corner. Build the exterior perimeter first, then the inner. Our soil was mostly clay, so we dug a bit deeper and laid the timbers over 2 in. of sand for better drainage.

Pouring Concrete

You’ll need a bit less than 1 cubic yard of concrete to fill the inside of the timbers to a depth of 3-1/4 in. That would be over 50 bags of dry concrete mix! Hand mixing would wear your palms to the bone and fix your back in a permanent bend. So call a ready-mix company and have them deliver 1 cu. yd. of concrete (about $90). This is a bit more than you need, but it’s worth having extra. To get the right concrete mixture, just tell them you’re pouring a sidewalk and they’ll send out the appropriate stuff.
Have a wheelbarrow or two ready along with a couple extra string backs when the truck pulls up. Pour the concrete into the forms and have a 2×4 ready like the one shown in Photo 3 to screed (smooth) the surface. The notches in the 2×4 screed are 2-1/4 in. deep. This will give you room for a sand to level the patio stones after the concrete is set. Next, screw the pier forms to the timbers.
Fill the pier forms with concrete (Photo 4) as soon as the area inside of the timber frame is poured and leveled. The concrete in the piers needs to bond with the concrete underneath, so work fast. A hot, dry day will give you only about an hour or less of working time, so don’t get sidetracked. The piers are the only part that has to work nice, so save the trowel work for them.
Pavilion 03
Screed the concrete 2-1/4 in. below the top of the timbers on the inside of both timber frames. Don’t worry about getting the surface smooth because later you’ll be putting a layer of sand over the hardened concrete to level the patio pavers.
Pavilion 04
Install the forms for the piers on each corner while the concrete below is still moist. Shovel a firm mixture of concrete into the forms and use a trowel to smooth it. The concrete can be shaped easily with a towel on the open sides of the forms.

Installing the Patio Pavers

The next day you’ll find the concrete hard enough to lay the patio pavers. You can buy these at most home centers or patio supply stores. Check the thickness of your pavers before you buy. Our pavers were a bit under 2 in. thick so we needed to level about 3/8 in. of sand (all-purpose or play sand from your home center) over the concrete as a bed for them. Make another screed like the one shown in Photo 3 with a notch cut the same thickness as your pavers. Pour in the sand and pull the screed board across the timbers to even the sand over the concrete. Next, lay the pavers in place as shown in the Figs. A and B. We selected two colors to complement the pavilion, but you can design your own pattern.
You may need to further level some of the corners of the patio stones. Just lift the paver and add or remove sand as needed (Photo 5). If your patio ended up a bit out of square, you may have to cut the edges of some pavers to make them fit. If so, but a masonry blade for your circular saw, put on some goggles and gloves, and trim the edges.
Pavilion 05
After spreading a thin layer of sand over the concrete, lay the patio stones in place. Sprinkle handfuls of sand to level the stones with the tops of the timbers.
Pavilion 06
Outline the post locations by tracing around the end cuts of the posts. Be sure you place the outer edges of the inner post 78 in. apart to get the right locations to conform with the beams above. This is crucial for the roof framing to align. Allow a 3-in. space between the inner and outer columns.

Making the Steel Post Supports

We made our 2 x 3 x 1/4-in. steel supports from a length of steel angle we purchased from a welding shop. You can cut the 5-in. lengths with an aluminum oxide metal-cutting blade placed in your circular saw, but it’s easier to have the welding shop cut them to length for you. Most shops have a shear that easily cuts the steel angle. It’ll probably cost about $1 per cut.
You can either drill the 9/16-in. holes in the post supports yourself, or if you don’t like working with metal, have the welding shop so the drilling too. If you do it yourself, use a heavy-duty electric drill. Start with a 1/4-in. hole, then enlarge it with a 9/16-in. bit. Be sure to clamp the supports in a vise to keep them from moving as you drill. Use a little motor oil on the bit as you drill to keep the bit cool.
When you’re done drilling the holes, file any sharp edges and clean the metal with mineral spirits. Spray paint the supports with two coats of rust-inhibiting paint.
Pavilion 07
Drill into the concrete piers to fasten the steel brackets made from 3 x 3-in. steel angle. The 1/2-in. concrete anchors grip the concrete as the nuts are tightened.

Fastening the Posts

Cut the cedar posts to length, then use the cut-off ends to help you lay out the locations for the steel supports. The posts should be 78 in. from the edges of the inner posts on each corner as shown in the Figure B. Mark the edges of each post location and the hole locations of the supports with a pencil. Drill 1/2-in. holes into the concrete to accept the concrete anchor bolts (Photo 7). This type of anchor is designed to grip the concrete as you tighten the nut. Drive the anchor bolts into the holes with a hammer, install the support, washer and nut and tighten the nut with a wrench.
While a helper holds each post against each steel support, drill 3/8-in. pilot holes through the support into the post for the 3 x 1/2-in. lag screws. Use a wrench to tighten the lag screws. Complete only two sides as shown in Photo 8.
Pavilion 08
Fasten each beam in place after clamping it to the posts. The bolts are made from 1/2-in. threaded rods. The beams are made from two 2×8 cedar boards.

Installing the Beams

You’ll also need assistance to get the beams in place and clamped while you drill for the threaded rod. Start with the longer beams as shown in Photo 8. Cut the 1/2-in. threaded rod to length with a hacksaw. Cut it 1/2 in. shorter than the measurement of two posts and the thickness of the beam. This will hide the rod ends, washers and nuts within the post.
Drill the countersink holes 1-1/4 in. deep into the posts. Then drill a 1/2-in. hole through the post, beam and the post on the backside. Drill very carefully so the bit comes out in the right location on the opposite side. You can buy a long bit at home centers. If you can’t find a long bit, can buy a 1/2-in. spade drill bit and an extension. Slip a washer and nut on the end of the rod and drive it through with a hammer. Put a washer and nut on the side and tighten each side with a socket wrench as shown in Photo 8.
Install the short beams the same way as the longer beams. These are fastened with just one steel rod. After the beams are in place, check to see if the posts are plumb using a level. If they need to be adjusted, install a 2×4 brace from the bottom of one post to the top of an opposite post, check for plumb again and nail it in place. Keep the brace in position until you’ve completed the roof.
Pavilion 09
Insert the threaded rods after drilling a countersink hole and a pilot hole. The countersink hole will recess the threaded rod, washers and nuts.
Pavilion 10
Position the notched stringers between the beams. You can bend 16d nails over as shown to hold them in place, then drill and insert the lag screws.

Framing the Roof

Install the double 2×6 interior stringers as shown in Photo 10. These stringers provide extra support as the roof pushes out against the beams. Nail the stringers together (avoid the center area) with 10d galvanized common nails, then notch the centers of each as shown in Photo 10. Fasten them flush with the top, and center each beam using two 5 x 1/2-in. lag screws.
Cut two longer hip rafters to the dimensions shown in Fig. C and fasten them together at the top with two 3-in. galvanized deck screws. Grab a partner and walk the rafter assembly up the ladders as shown in Photo 11 and nail it to the beams with four 10d galvanized common nails (two nails per side). Be sure the hip rafters fall directly over the intersections of the beams at the corners.
Next, cut the two remaining hip rafters; these are 3/4-in. shorter at the top than the other pair to make up for the thickness of the rafters already installed. Nail each of these to the pair of hip rafters.
Cut the four common rafters. You’ll notice in Fig. C that they have cheek cuts on the top. These 45-degree cuts on each side allow the common rafters to fit against the hips tightly. Nail them at the center of the beam and at the top as shown in Photo 12.
Next cut the jack rafters. These rafters have a compound cut at the top as shown in Fig. C. Four of them are right-sided and four are left-sided. Nail them to the beam and to the hip rafter with three 8d galvanized common nails as shown in Photo 12.
Now it’s time to cut the 2×8 fascia boards (Fig. A) and nail them to the rafter tails with 16d galv. common nails. You’ll need to tail them so 3/4 in. of each rafter is above the inside edge of the fascia. This will allow for the roof decking to sit flat on the tops of the rafters and the outside edge of the fascia.
Pavilion 11
Position the first set of hip rafters onto the beams. Get some assistance because this can be awkward. The hips should fall directly over the intersections of the beams.
Pavilion 12
Nail the jack rafters to the beams and hip rafters. Use 8d galvanized nails when nailing the jack rafters into the hip rafters.

Decking and Shingling the Roof

Our design uses 12-ft. pieces of 5/4 cedar decking for the roof deck, because it’s great looking from the inside and thick enough to keep the shingle nails from poking through. Starting at the bottom, place the first board so it hangs over the fascia 1-1/4 in. Nail the decking into the rafters with 8d galvanized common nails. Place the nails carefully because you’ll be able to see any goofs from inside the pavilion. Push the boards together so there aren’t any gaps between courses.
Once you’ve finished decking, staple 30-lb. roofing felt over the decking. We used No. 2 cedar shingles on the roof. They have a few knots but are rustic and add some charm to the structure. Your first row of shingles will be an underlayment for the first course. Let them hang beyond the bottom of the roof deck 1/2 in. Then nail shingles directly over this course, making sure to offset the seams with the underlayment course. Use 3d galvanized box nails. Start the next course 5 in. above the first. You can have an even reveal, or stagger the shingles, or stagger the shingles as shown in Photo 14.
Staggering them randomly gives a more hand-built look. Complete each side and trim the shingles as you go with a fine-toothed plywood blade in your circular saw. You can also shave the edges to fit with a utility knife of plane. To finish off the seams above the hips of the roof, use preassembled cedar roof caps, which are sold at lumberyards.
Finally, it’s a good idea to seal the entire pavilion with a deck sealer. This will keep the shingles, beams and posts from cracking in the sun. After two of three months, check the bolts, nuts and lag screws. As the wood dries and shrinks, they may need tightening.
