I have a bandsaw with a cast aluminium frame (Inca 205) thats quite badly out of alignment. Today I stripped all the parts off and using various straight edges and clamps, now have it clamped up and all square. I suspect when I remove the clamps it will spring back to its twisted form. If I heat the frame with a heat gun while its cramped do you think this might help retain its new shape ? If I left it cramped for longer than overnight would this help ? Any ideas ?
