Hi,
I just finally got around to putting together a bench top drill press I
picked up from Grizzly months ago. Everything seemed ok until I turned it
on. There's quite a bit of vibration (enough that a piece of wood on the
drill press table moves around by itself).
I went ahead and checked the spindle alignment and noticed that while it's
dead-on aligned to the table side-to-side, there's a slight pitch towards
rear. Any thoughts on how to fix this?
I also noticed that while the drill is running, the v-belt seemed to wobble
(and thus the cause of the vibration I noticed). My guess is that the v-belt
had been sitting in the same position for a long while and memorized that
shape. I was going to replace it with a link belt, but the belt on this look
much narrower than the 1/2" belts I use on my tablesaw and bandsaw. The
outside width of the existing belts measure to be 5/16". Do link belts this
narrow exist? If so, anyone have a source where I can buy some?
Thanks!
Winthrop
Follow up:
I was able to fix the spindle alignment. Ended up there was little play in
where the motor/spindle mount onto the main column. I shimmed it and
re-tightened the bolts and now there's no more run-out!
As for the vibration, I discovered that the motor and the spindle pulleys
aren't lined up! The spindle pulley is almost 1/2" lower than the motor
pulley. I'm looking around for a 3 jaw puller so I can adjust the pulley
heights to match up. Also noticed the spindle pulley has a slight wobble
(placed my level on it and rotated it around). Hopefully after I address
these two issues most of the vibration problems with disappear.

I have a Craftsman Bench top drill press that had amazingly low runout
out of the box but a pretty junky v belt like yours and it causes
vibation like yours. I've been looking for a narrow link belt for years
and haven't been able to find one.
