I'm trying to make a 5'X10'X3' (xyz) milling machine in order to make woodcarving and automotive body panel molds. Also trying to keep the prioce down as low as possible.

What parts do I need to and what manufacturers should I be looking for?

bearings?
ball screews?
stepper motor size? torque? type?
and others that i no doubt have missed...
