Hello Ron,

My name is Jim Bonner. I have a Dalton B-6. Thanks for setting up
this group.

I'm not sure if the B-4 uses a ball bearing or a fiber washer for a
thrust bearing. (the B-6 uses a ball bearing) You could start
with .002. After some turning, you could re-check the clearance and
adjust accordingly.

Jim

Trying to get an old B4 up and running. The spindle had 0.011

of play from left to right. I adjusted the thrust bearing to give me
about 0.002 inches of play. I originally made it less than 0.0005",

but

then after thinking about it backed it off to 0.002". Last thing I
wanted to do was make it too tight and burn the bearings.

Any thoughts?
