I am planning to build a fixed gantry router, and have the general design more or less figured out, and need help with one last bugaboo.
From reading posts here and some googling, it's clear that the leadscrew should be supported independently, and not depend on teh stepper motor for mechanical support.
Now, is there an easy method to support teh screw properly on threads? All of the methods I see seem to have the threads taken off on a lathe so that there is a smooth surface for bearings to mount on. I want to do this as cheap as possible, and do not have access to a lathe, so can anyone reccommend a method to fix bearings onto a threaded part of the screws at the ends?
Thnaks,
Lukas
