Bend a big circle

[Randy]

I have a rotisserie that I built my fuselage on. I am thinking if I used 1/2 of it with a big circle jig on the outboard end of my wings the covering / painting process might go a little easier. I have a 21' x 3/8" rerod that I could use for an 80" diameter circle but - - how do I bend it into a circle that big ?? I have seen photo's here of such units but never needed one - - until now
Thank you

P.S. I have a sheet metal roller that will bend tube but maybe not solid 3/8" stock and I would have to be at least 4' high to do it - - gotta be a better way . . .
