I think it's probably normal to have to bend on a hot pipe even after using the machine to make it perfect but it would be nice to get real close too.
I build on an open work board in the traditional Spanish way so it's important.

I only make classical guitars but I haven't found a formula to bend sides without springback. I look at the bending form as a short cut to get 90 percent there but refine the last 10 percent by hand; I feel sides should be perfectly bent so they adhere to the form drawn without a mold even if you're using a mold. The maker in the mountains of Malaga whom I apprenticed under heavily reinforced this ideology and I always strive for rims built without unneeded tension.
