This should be an easy question for you experts. I built a square circle and found the hardest part is getting the right set of circles. The inner one I have is smaller in diameter then I would like. I think that it should just fit but it is smaller then that. For those do it yourself types, where do you look for concentric circles? Or do you make them yourself, and if you do what kind of material do you use. Oh, I picked up a can of Pirouline cookies and a emptly container of clorox wipes. Showed it at the local ring and didn't hear any complaints, of course my family at home like wise hasn't said, oh I see what's going on, so I guess it's working but if ever I do it again for a different size it might be nice to have some ideas.
Thanks,
Dick

I used a jumbo phantom tube that I bought at a magic shop for the outer tube,
and a 4 inch diameter PVC pipe for the inner tube.

Depending on how much money you want to spend you can go to a metal shop and they will make you the tubes to your specs. There are a number of people on here that can give you some really good advice on the tubes. Everything from metals to cardboard. I used a heavy papaer,a little heavier than poster paper for an outer tube on one square circle I made. The inner tube was made out of a really heavy paper, can't rememeber where I got it but it worked great. I would say go as inexpensive as possible, note I did not say cheap. Spend a little on it and find what works. Mkmagic had a good idea with the 2 tubes. If you start to brainstorm then you will come up with something really good. Also look in the "workshop" forum, there is all kinds of threads about square circles.

Good luck

I have used plastic tubing. I am not quite sure of the type of plastic but its dark gray, easy to sand and paint. Cheap too.

Thanks for all the replies. Didn't realize there was a workshop forum. Michael thanks for the link, that's just what I was looking for. So now when I have the time to do another of a different size I know where to go.
