As I read through wood mill build logs, I see lots of different bearing/drill rod combinations.
I want to use 3/4" drill rod for my Z rails. I've tried searching enco, msc, and mcmaster and I can't really seem to find decent bearings that aren't in the $30/pc range.
Does anyone have any suggestions? I'm sure I'm missing something. I don't mind changing away from 3/4" drill rod if necessary.
