Just a few notes on bearings for the Lathe and mill.

Headstock/Spindle take 1 each 6203RS and 6203ZZ bearings.

Mill CNC leadscrews take 2 608RS bearings each axis.

6203 = 17MM ID 40MM OD 12MM wide

608 = 8MM ID 22MM OD 7MM wide

RS= Rubber shield

ZZ= steel shield

The 608's are common rollerblade/skateboard size

Still not sure what the lathe crossslide bearing is.

Well Nick says the crossslide takes a 635RS 5x19x6mm Shielded Bearing
