I am about to start on a steel framed machine and was wondering what material I can use for linear rails. I was thinking of using 3/4" drill rod or something of that nature with bronze bushings.
I can't affortd THK rails and such. My tolerance requirements are not 0.001"... they are more like 0.050"
I intend to use the machine for 3D sign cutting and 2D plasma burning of 1/4" plate steel. The machine frame size will likely be about 3' x 4' or so.
What size of machine frames have you guys found the most useful?
Thanks,
Eldon.
