I want to mount a spiral of rebar on a plywood backing. What length of rebar is needed if the backing is 3'x4' and I want the result to look something like a shell.. so not multiple concentric circles.
The rebar would come up from the center, turn in an even counter-clockwise circle making one complete revolution and then touch the upper left corner.
Does that make sense? My paint sketches come out crappy and I don't have a scanner here.
Any help appreciated.
~~~UPDATE~~~~
Well, here's the Finished piece. The stripey thing is a mock up I made, my wife helped me with the math on that, and you guys turned out to be accurate on the length needed.
Overall, I think it cam out alright... I kind of feel, if I were actually going to persue it, that this would be a first draft... Manually turning that rebar with a conduit bender is for suckers... I'd go to a machine shop and have some guys help me bend it perfectly if I were to do it again....
Thoughts???
