Re: [GrizHFMinimill] Rough bearings and Belt drive etc
- Hi David,
Did you ever take the top cover off the bearing and clean it out BEFORE you ran the mill for the first time? They drill and tap a hole there after it is assembled and there is a ton of debris left in there to reek havoc!

A few weeks ago I posted about spindle run-out due to my whacking the drawbar to release a
boring head from the Morse taper.
The hammering has done some damage in that I have a vibration at certain speeds.
I just installed a Steele belt drive conversion I bought from LMS and now that the gear noise
has gone I can hear that the bearings are rough. I can't feel any roughness turning the
spindle by hand but it sure makes some funny noises (and no, it's not the motor).
So, I bought a new spindle with the belt drive kit and when I get around to it I'll buy new
bearings and put the new spindle and bearings in.
Oh, BTW, I found that the trick to getting the boring head taper loose is to remove the boring
tool from the head and use a bar in the horizontal tool hole to twist the head clockwise (to
avoid unscrewing it). After the spindle is locked and the drawbar is loosened of course :-).
