Modifying Calumet C400 back
Hi, I want to modify my C400 so that a grafmatic will fit. The only reason it won't, as far as I can tell, is that the leaf springs aren't long enough. I don't have the facilities to work with spring steel, so I'm looking for other ideas. Coil springs can be easily found, but the leaf spring also keeps the moveable part of the back square to the rest of it (i.e. allows movement in one axis only - in or out). Has anybody attempted this modification before?
Before anyone points out the obvious (use a DD, not a grafmatic) the various advantages of the grafmatic have wone me over and I would rather not use DDs at all if I can avoid it.
