Roy,
I already have tapered bearings but my problem is that they are
mounted tight and I can't manage to reduce the clearance between
them.

What this whole thread is overlooking is the fact that the
OEM bearings are deep groove ball bearings; the cheapest option!
An upgrade to angular contact bearings gives more thrust
resistance to the spindle, resulting in the lathe becoming more
rigid. Tapered roller bearings would be the most rigid, but,
sealing them is much more complex.

I upgraded mine to angular contact bearings years ago &
have been happy with the results! My preload setting method is
to simply adjust preload for slight heating at full speed.
