The raised land on my spindle plate measures 2.154 rather than 2.165
as given on the mini-lathe site. Sure enough, the recess in the chuck
measures 2.165.
In order to mount my 3 jaw chuck I first snug the nuts slightly, put
a rod in the chuck, and use an indicator on the rod. I rotate the
chuck so the high point is up and tap the chuck on the top with a
block of wood; this is not a well controlled process so it typically
takes several minutes to get TIR between 1 and 2 mils, when I tighten
the nuts.
Is there a better way to center the chuck?
Is the mis-match between the land and the recess common? I expected
the chuck to center itself on the spindle land but this mis-match
apparently precludes that.
