schu777 Posted August 3, 2014 Report Share Posted August 3, 2014 Earlier this spring I started to drill out some maple using a Forster bit of 1.75" (or 2") and about 3/4" in the drill wouldn't drill and just spin on the pulley. At first I thought it was the drill chuck spinning, but by hand I can hold the drill chuck and hold the pulley and see the shaft spin on the pulley. This drill press is a Shop Fox W1668 - so I'm hoping someone has some recommendations for fixing this issue, as I really would like to continue on with that project. PS: Yes, I know it's August and I was having issues with it in the spring - but we all get busy with family/work and other projects.

Tpt life Posted August 3, 2014 Report Share Posted August 3, 2014 If I understand correctly I think you need to replace a key. The pulleys are usually pressed onto the shaft with a key in a keyway for alignment and purchase. Does this seem like the correct line of thinking for what you are experiencing?

..Kev Posted August 3, 2014 Report Share Posted August 3, 2014 Sounds to me like C is correct. There should be a shaft key that has most likely sheared off. Quote Link to comment Share on other sites More sharing options...
Freddie Posted August 3, 2014 Report Share Posted August 3, 2014 Sounds to me like TIODS is correct about C Shaffer being correct about your pulley key needing a replacement. 1 Quote Link to comment Share on other sites More sharing options...

RichardA Posted August 4, 2014 Report Share Posted August 4, 2014 Sounds like the "key" to the problem has been solved! Quote Link to comment Share on other sites More sharing options...

krtwood Posted August 4, 2014 Report Share Posted August 4, 2014 It may be the belt slipping on the pulley rather than the pulley slipping on the shalt. Try loosening the knobs on the motor and pushing the motor back more as you tighten the knobs. With that said, if it's hard maple and your 2" forstner bit isn't especially sharp you may have issues anyway. What you can do is start the hole with your large bit, then drill to depth with a smaller bit, then come back with your large bit again. If you don't start with the large bit you won't have anything to keep it centered. Quote Link to comment Share on other sites More sharing options...
TheFatBaron Posted August 4, 2014 Report Share Posted August 4, 2014 If the belt is slipping as soon as the bit engages, try pulling it off and checking for glossy spots. If the belt slips repeatedly, it may have been polished/burnished/whatever, and some high grit sandpaper and a light touch may restore some grip.

schu777 Posted August 6, 2014 Author Report Share Posted August 6, 2014 I've been in contact with Grizzly support - about one email a day. It's the shaft to the pulley that is slipping that needs to be taken off and cleaned. Now the question is when I'll get to it... As for the key - the part diagram of the drill press doesn't show one - so I'll find out when I take it apart... If I get around to it, I'll take some pics and post them as I'm doing the "project".

wtnhighlander Posted August 6, 2014 Report Share Posted August 6, 2014 If there is no key, perhaps there is a flat on the shaft, and a set screw in the pulley? A screw backing out sounds more likely to happen that a key breaking, although I've seen both. Broken keys I've seen were generally on motors over 100 hp in high torque load applications.

BRINTN Posted December 20, 2021 Report Share Posted December 20, 2021 shu777 what was the outcome once you took it apart? I have this same drill press and am having the same problem. Quote Link to comment Share on other sites More sharing options...
