I''m sure I did a more thorough job of reasseling the lathe than the Chinese factory which also helps the rigidity factor.

Now let’s say we want to build a lathe spindle with a spindle bore of 2″. Let’s give it a 1″ wall thickness, so we need bearings with 4″ ID which is 101mm.

Dec 16, 2021· The "thickness" of a 6" chuck is approx 3 3/8" (depending on manufacture), not including the back plate if it has one.
