I'm in the process of getting materials together to build my first CNC router. This first machine is mostly proof of concept and a learning experience. As such, I'm putting it together from anything I can find laying around my gararge.
Okay, here's the question. I have a box of brass bearings that appear to be for sliding screen doors. They are about an inch in diameter and have a half circle bearing surface and no detectable play. I'm thinking I could put them on the top and bottom of a rail with a matching bearing profile. Has anyone tried this? Think it'll work?
