I’ve been having some trouble with my drill press lately, and I was hoping someone on here could point me in the right direction. A while ago I bought a very, very lightly used Reliant drill press but I haven’t put it through the paces since I’ve been slowly assembling the rest of my workshop.

The issue is that when I begin boring a hole with it, the belt slips inside the pulley housing. I’ve tried putting more and less tension on it, changing speeds, but it doesn’t seem to matter. Thus far I haven’t even put the press in to more than some very soft pines and spruces. I’ve been using fairly cheap bits from Ryobi, but even when I use a slightly better bit I’m still running in to the same problem.

Would a link v-belt solve this problem? I sure could use less noise from it as well.

The v-blet might very well solve the problem but ive never used one on a DP. Have you inspected the belt thats on it? Id bet that if its older it may be prone to stretching out once it gets warmed up and thats why its slipping. At least thats my best guess.

I had a craftsman drill press and I put the link belts on it and had great results! Eliminated much of the noise and all the vibration. Sounds like your belts have run their course. I don’t think you have anything to loose.

V and A belts have some different available profiles. The
belt sides should run inside the sheave, and the more
side surface contact the better.

Belt sides can get glazed I think. Try roughing up the
sides of the belt with 80 grit sandpaper and check the
sheaves for residue.

In the old days they used belt dressing like violin bow
rosin to make the belts grab on the pulleys.

Your belt may be stretched out and riding against
the inside of the sheaves, not the sides. That may
cause slippage.

Link belts solve slippage problems in a few different ways but
they are a bit spendy compared to a regular belt. They
generally perform very well though.

Are both the pulleys turning and the belt is slipping around the front one , or is the front pulley turning but not your chuck when pressure is applied ? Is the chuck mounted via a Morse Taper ?

Check what Dusty56 says. I have a Craftsman and the set screw on the drive pulley was always loosening. I applied loctite and it hasn’t slipped since. It only slipped when I applied pressure.

First thought was glazing on the belt and then find out why it is glazing, check pully to be sure it is not slipping. Set screw, pullys aligned. Just putting on a v belt may not solve the problem. I run regular belts on my Clausing and good ole Powermatic and never have any slippage problems.
