I'd love to post a picture for you,but my printer has been out of ink for at least 6 months!--and I wouldnt have a clue how to post it anyway,despite having read the instructions on here many times--I still am not very good with the computer despite having one for a few years.
You should be able to get the idea by reading the quote--I simply used junk iron pipe I got at the landfill,cut it into 3 foot pieces,pounded it in the ground with a 18lb sledge hammer,left about 18" sticking out,slid the 20 ft PVC pipe over one,bent it into the arch shape and forced it over the other pipe opposite it(it doesnt bend as easy as you think,its fairly difficult to get it over the other pipe)--I used 20 ft PVC schedule 40 1-1/2 pipe,I had to go to a large plumbing place(Snow and Jones)to get 20 footers(Home Depot and Lowe's only had 10' peices,coupling 2 ten footers wont work,the couplings snap easily!).I can do chin ups on the arches with no problem,and I weigh about 175 lbs!.I used six of theese pipes to make a 20 ft long x 12 ft wide "quonset hut"style shelter--I put 1x3 strapping on the outsides of the pipe in the center,and at 10 and 2 o' clock positions(I used conduit clamps to avoid driving screws into the PVC pipe,but my friend just drywall scewed his strapping on,seems to have little or no effect on the strength of the pipe.I used a blue tarp 20x30 ft for the cover,it lasted about 2 years,then I got some genuine greenhouse plastic(used)from a local nursery that was replacing all their plastic.You can get 6mil plastic rolls at home depot too.The height is only just tall enough so I can stand up in the center--I'm 6'4"--if you wanted you could make a higher one by building a short wooden studwall and hole saw 1-1/2 holes in the top plates for the PVC pipe.You do have to anchor the arches down by screwing them to the iron pipes or tying ropes to a stake in the ground so it wont blow over in a high wind.It looks very similar to those "Cover it" instant garages you see everywhere. As I said already,its been up for at least 5 years with no major problems,but the blizzard we got last december(over 2ft of snow!)did some damage to the plastic(I used double layers,since it was free and I had plenty of it!)but only the outer layer got damaged because I had to use a garden hoe to remove the heavy wet snow off it--I bet there was about 1000 lbs of snow on it--I could not beleive it when it sprang right back into shape--I can still do chin ups on the PVC pipe,its not weak at all!.The only other problem I had with it was the local fuzz investigated a house alarm call next door--they were curious as to what was growing in it!--but they were dissapointed to see it full of junk! /forums/images/graemlins/rotfl.gif
