Linear Guides with Teflon Bearings
If the price is right, I'm thinking about making a small (6"x6"x6") DIY jewelry mill based on Pacific Bearings, Dolphin series of linear guides.
According to their white paper, their Dolphin series of linear guides have less than .0005" end-to-end yaw and pitch and typical ball bearings have .0035" end-to-end yaw and pitch.
Anybody have any experience with these?

Poor planning on your part does NOT constitute an emergency on my part!
