For those of you that use metal arbors, and bushings in you clocks I have a couple questions.
1. do you use steel arbors, and brass bushings?
2. do you use "hobby shop" brass tubing for the bushings?
3. If you use steel arbors, what is your source for the materials? How do you
size the diameter of the arbor to be appropriate for the loads--so it won't bend?
I noticed in the Bearings forum it was suggested that friction is minimized by using dissimilar metals together
i.e. steel on brass.
Any info appreciated.
