I have 2 Grizzly H6265 Wood Lathe Chucks and I talked the high school into buying a couple. Well we have only one now and it was almost scrapped, too. The first one had a jaw come out and someone threw it away with the chips and a set of jaws costs as much as a new chuck. I found the second one today with a jaw out of it and the problem is that Grizzly uses a 9/32” long 1/8” roll pin as a keeper to keep them from backing out. After while that pin slides down into the hole which is about 7/8” deep and the jaws don’t hit a limiter and come right out.
I fixed that chuck today and both of mine with a stepped pin that goes from the back of the chuck to sticking out 1/8” so it cannot retract and provides a positive limit for the jaws.

This is what it comes with:

I drilled out the 1/8” hole about half way up to 3/16” and turned down a 3 /16 pin to 1/8” and stuck it up in the chuck so it just fit in the back.

Now there is a positive limiter in the chucks!!

Nice retrofit on the pin. Too bad the other jaw was lost.

Great, simple solution Jim. I’m wondering how long it will be before Grizzly updates their design. They should be contacting you to reward you for such a useful design upgrade.
Have a great day.

Sounds like Equipment should NOT be allowed to be in the hands of young people that have NO CLUE of how to USE them… or Fix them… (??)

Hi John, I have just sent this forum note to Grizzly after talking to the CS rep. for about 20 minutes. I repaired 5 chucks now with the stepped pin and don’t worry about the jaws coming out again on them. I wish they would send the school and new chuck at the least! In 2016 the chuck was $117 in my old catalog…it is now $174.

Cheers, Jim

How else should they learn?

Nice save Jim. Grizzly normally has decent stuff, but I have had some issues in the past with the detail things like your issue here.

Throwing stuff away?! After messing it up? ... NOT asking for Help? ... Instruct them…? LOL Yes?

Hi Jim, I have a H6267, mine is the 1-1/4X8tpi version. I believe yours are the 1X8 adapter. I think that is the only difference in there chucks. Different numbers for the adapters. If you would like to replace the jaws you will find that the vicmarc vm100 jaws will work fine.
I keep a vicmarc pin Jaws mounted on mine most of the time.

I would expect Grizzly to send a couple of their upgraded chucks to you for “in the field” evaluation. Then you could also report your findings right here.

Nice stop pin Jim. I had the same problem on their smaller model #G8784? I don’t like changing the jaws all the time especially when you have a few projects going at the same time. Great job saving all those chucks. They should last forever.

Hi Joe, you should see the lathe room after I have not been there for a few days. Tools are out all over mixed with wood chips .It is no wonder a jaw got thrown out. I am repairing stuff on the machines every week. Today I have to take the spindle out of a Jet lathe to replace a missing/broken snap ring

Hi Big John, do you get both pieces of the jaw with the Vicmarc set or just the top pieces? If it was just the top piece that was missing, I could have turned one, but the bottom piece with the radiused grooves to fit the scroll plate was gone too.

Hi John. It would be nice if they sent us a new chuck!, but it was negligence on our part that it got discarded.

Cheers, Jim

Jim,

Can you make some rules to CLEAN UP after use and BEFORE leaving the room? :)

Hi Jim,
I hope that you will recall the visit you made to my shop, you made a comment about my Grizzly chuck.
Well, I am happy to say that I still use that chuck and after several years of use and as I learned how to turn, some abuse, my Grizzly chuck is still operating normally; so no complaints here.
In looking at your photos, I noticed that your chucks are very used.
Great save on the retaining pins, but what would one do if they don’t have a metal turning lathe?? So I called Grizz .. they do have some replacement parts available.
To bad that the chuck part was lost, but look at all the spare parts you have now to keep the other chucks in repair.
Keep them kids turnin’

Hi Joe, I’m just a volunteer there and not the teacher…but the new teacher is much like that with a desk that is littered to almost beyond use as a desk! I make comments to him about cleaning up the place but it does not do much good.

Hi Mike, Glad to see you got to turning. I think the lathe is the most fun tool in the whole shop. When I get students on them, they seem to get real creative!! Grizzly had replacement jaws with the lower scroll pieces but you have to buy a complete set, because they are made as a set, and it was as much as new chuck then.That old chuck was scrapped.

Cheers, Jim

That is interesting read and good save Jim. I was looking at Grizzly chucks for a long time and ended up buying Nova and have not had any problems. A quick look at mine and without looking at a parts diagram it appears they must be made a lot different.
