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.

Hi Joe. I enjoy turning and will put up with a lot just get to help out the kids. I learned how to pull the spindle out of the Jet lathe today to put in a new key, install a snap ring to hold the pulley in place and I slit the back of this big hardened nut so it would tighten on the threads. I’m having a hard time finding a heavy duty 3/4” snap ring though. There is one on the other jet lathe, but E replacement parts says it is an E clip and it is not.

Hi Mark, we have a Nova chuck at school, but it tightens backwards to a regular one and I always have to remember that. it is made by those guys that drive on the left side of the street. I looked at it today, too, and could not see how they limit the jaws from coming out, but they do.. There must be a pin or screw down inside.

Cheers, Jim
