I bought a Delta 17-965 16.5" drill press, put it together, and am experiencing
unacceptable vibration (the head shakes, the table shakes, everything shakes)
that didn't exist on the cheap Craftsman some electrical engineers put in
lab space I shared.

Belt tension makes some change but does not appreciably reduce it. With the
belts off there's a tiny amount from the motor. The belts are oval shaped as
shipped but don't seem to have a real set. Regardless of belt tension the
idler pulley bounces arround a lot. A straight edge across the pulleys shows
the spindle and motor pulleys are level but the idler pully is significantly
(1/4"?) below them. I have not yet put a dial indicator on anything to
look for runout.

Help!

The vibration is, more than likely the belt. Some new machines are coming
with an import belt that is just too stiff. Some would steer you to a link
belt however, I would either let the one you have run at high speed for a
while or replace it with a new regular automotive v-belt.

I steer you toward the link belt. Go to the link belt... gooo..... I
could not balance a nickel on my TS and the motor would bob up and down
violently- I put a link belt on and viola- no more vibration. I can now
start, run, and stop the saw with a nickel balanced on its edge. Im
sure a dime would work too. Goooo to the link belt....

I agree with Dave that the belt would be the first suspect. I've got
the same model; it runs smoothly.

I just measured my 17-965, and the idler pulley is 3/32" lower than the
other
two, it runs very smoothly. I agree with the other posters it's not likely
to be
the problem. If the drill press is new call Delta.

Auto shop V-belts changed the sounds some but did not reduce vibration
appreciably from what I had with the included belts.

With a link belt nothing knocks or rattles and the vibration is only a little
worse than with just the motor running without belts installed. This is
useable (nothing walks off the table) but still seems excessive.

I need some frame of reference as to what's expected...

Will you please just call Delta? Your machine is performing a lot worse
than the same model I bought a year ago. There was, I believe, a string of
vibration problems that Delta knew about, and fixed. Since mine worked
just fine, I put the info into the 'don't worry about it' category.

How many hours are you going to put into a $400 drill press?

I feel better know.

Your DP should not have any significant vibration. My Delta 17-968 does not
have any vibration at all. Check for bent pulleys or shafts.
