Hi All, I am having an issue with my Jet Model JDP-17MF Drill press.

The Forstner bit I was using suddenly stopped spinning when started to make contact on the wood. I opened the top and turned it on again with out pulling down on the quill and the belts and motor were spinning just fine so I pulled down on the quill and when I made wood contact the bit stopped but the motor and belts were still spinning.

I got on a ladder and found the pulley set nut had come off of the pulley directly over the Quill and Bit shaft. I placed it back on and tightened it up the best I could. Very small space to work inside the pulley so I used a heavy pair of needle nose pliers to do the job.

As soon as I turned it back on it just unwound and came back off right away. I have the original manual and looked for a possible locking key or something that has gone missing but I don’t see anything listed nor do I see where one would go.

Has anyone had an issue like this or any idea’s? I have had this drill press for a number of years, it had been in storage for about 3 years but I can’t imagine that would cause the issue. I had a large forester bit 2 5/16” in it and was able to make 5 holes when it suddenly stopped working. I was only running at about 380 when it happened.

Thoughts?? Thanks in advance.

Looking at your manual online, I don’t see another nut either than the one you are describing. That being said, there are also supposed to be a retaining ring and drive sleeve inside the pulley. The later might be what the retaining nut tightens against. Not personally familiar with this model but most drill presses would be running in opposite direction to how this nut screws off. You haven’t rewired anything have you? Also try a different socket on a different breaker just to make sure.

Have your say...
