Re: Bearings vs Bearing Blocks

If you don't have a mill you might want to give this a try:

Note that you also need to buy the arbor (http://www.trick-tools.com/Slugger_S...rbor_18255_449) too.

I have not used one myself, and can't find out how accurate a hole they make. My guess is "good enough", especially for a team working with simple tools. [Update: one site says 0.0005!]

Step drills in thin (0.60-0.125) material doubled up and rivetted together could be another solution for you.
