Anyone have experience with precision fitting of bearings?

I’m going to be building a “5 bar”/dual-arm scara robot (pantograph mechanism). I have bearings that I would like to secure into aluminum plates for the joints, however I have not done this before and want to get as good a fit as possible (including precise machining of the holes to accept the outer races). Any help would be appreciated or if you know someone who might be able to give me advice given the tools that we have available.

The outer race is 24mm dia btw, and the plate aluminum is 1/2"

Ok looks like I either need to use a 24mm reaming tool (expensive)? Or a boring tool. Or both.

I think I’m gonna use a boring tool, but if anyone has access to a 24mm reamer and wants to help me make the holes for this robot arm I would appreciate it.
