Good Afternoon All:
Finally got most kinks out of my alignment problems with
replacement parts from Homier. Headstock, saddle, cross-slide and
compound assemblies were replaced. Accuracy is dramatically improved,
although new problem is headstock is 0.015" lower than the tailstock.
What would be the preferred method of correction? Should I shim the
headstock, and if so, is there a difference in brass vs. steel shims?
Or, should the tailstock base be carefully cut down? Replacement of
the parts has improved accuracy greatly, but due to this height
difference, I get a slight chatter and taper 0.0055" on a 9.5" length
of stock. I attribute the chatter to the height difference as the
tool advances toward the headstock. If you advise that shimming the
headstock is the preferred method, I would also consider upgrading
the spindle bearing to ABEC-3 units, in contemplation of eventually
using a 4 or 5" 4-jaw chuck on this lathe. Have any of you changed
these bearings? If so, any notable difference in how the lathe
sounds/operates? Any suggestions/recommendations would be greatly
appreciated.
Regards,
Nick
