Very nice! Thanks for the insight! So judging from your photos, it looks like you use a reamer to make the bushing and bearing holes more precise? Would an end mill leave the fit sloppy?

I first drill undersize, then bore, then ream to finish. If I want real precision I'll hone the bore. On the lathe I always drill, bore to make everything concentric then ream if necessary or hone.
