Penn State Industries has a special going on with their utility 4 jaw chuck system. Wood Magazine had given positive reviews of the system. Right now, the chuck comes with a set of jumbo jaws for bowl turners. You can take a look at it here. I have it ordered right now along with a 3/4” 10 tpi to 1” 8 tpi spindle adapter. I have a Harbor Freight lathe with a strange tpi spindle setup that is not uniform. Fortunately, PSI has several adapters that can convert lathes with proprietary spindles. I am looking forward to the upgrade and believe it will really make the lathing experience much more pleasurable. I will post a review after I put it through the paces.

David,

I guess you’ve had the 4 jaw chuck for a while now…how do you like it? Did they have one to match your spindle?

I have used the spindle adapter and the chuck for a few months and am pretty happy with it. Only complaint I would have is that the jaw tightens and loosens by twisting it with 2 wrenches. On occasion, working a piece will cause the jaws to slacken, requiring re-tightening or the piece will slip from the jaws. The adapter for the HF lathe worked real well. Only issue with using the adapter is that you move from a 3/4 inch spindle to a one inch spindle which causes the tailstock to be out of center. I have had to raise the tailstock by shimming in order to get it centered on the piece in alignment with the headstock. This is not the fault of the adapter though.

I have upgraded my lathe to a heavier bed Delta and will eventually upgrade the chuck to a Nova or Barracuda system. The locking mechanism for these have sockets on the side that allow for a much more solid grip. But, for under $100.00, the utility chuck with two sets of jaws and a set of jaws for bowls can’t be beat.

Interesting that it would loosen up as you are turning. Is there room for a lock nut or one of those star nuts to go between the two ‘nuts’? Are there star nuts large enough I guess is another question. Glad to hear it works for you!
