Hello Steve, I have a Powermatic 4224BHi Manny. Remind us again of the lathe it will be used with.
Vicmarc- thumbs up! My 25 year old VM120 is bombproof. (I also have 2 Talon chucks which are great on my 12" lathe.)
Chomping down my lunch and thinking about this, I've boiled down chuck choices this way: 12" swing and smaller, and 1hp and less, and 1" spindle size, go with the smaller VM100 chuck. Over 12" and greater than 1hp, and increased spindle sizes, go with the VM120 chuck. This is the same rationale Oneway had in the later-90s when they introduced the Talon (VM100 competitor), designing it for the mini lathe market. A Stronghold on a Jet Mini lathe was like driving 10d nails with a 4lb maul... Same with a Vic VM120.
The VM120 weighs 8 pounds before jaws, and shark jaws get heavy fast as their size increases. 10-12 pounds total, a lot of rotational weight for the smaller motors, and there's no wood yet. Or tools cutting the wood.
If you've been watching Richard Raffan videos where for the past few years he was turning on the 12" VL150 lathe, he used the smaller VM100 chucks (4'ish pounds for the chuck body). When he stepped up to the larger 16" VL200 lathe and its stronger motor, he also invested in the larger VM120 chucks.
Raffan really shows how to get the best grip performance from the Vicmarc jaw sets. You can't go wrong with Vicmarc.
Oh yeah, big lathe, big chuck, good as gold.Hello Steve, I have a Powermatic 4224B
You never know when you may want to change out the insert when using a different lathe, e.g. M33x3.55mm or 1"x 8 tpi especially when demonstrating. It would be less expensive to buy an insert than a whole new chuck.A couple reasons to buy direct, when I looked no US dealers had direct thread chucks available, you had to use inserts (which for me always unscrew at inopportune moments, even with set screws); even with higher postage and tariffs added the total cost is quite substantially cheaper (like $100 less for a VM120).
are you talking about this: https://www.vicmarc.com/product-page/superseded-2-step-dovetail-jaws?currency=USDYour list looks good to me. Although I don't think the multi purpose jaws are a good idea. I would get the 3 or 4 inch dovetail jaws for the 100 and 6 or 7 inch jaws for the 120. I have a Vl300, and I probably use a the vm100 chuck more often than the vm120. Large chucks with small jaws never made much sense to me.

I switched from Nova to Vicmarc last year. I’ve been using the vm100 and the vm120 almost daily and assure you that the insert will not unscrew unless you really want it to.You never know when you may want to change out the insert when using a different lathe, e.g. M33x3.55mm or 1"x 8 tpi especially when demonstrating.

I've never had even an inkling of a moment of doubt with my chuck insert loosening in an unplanned way. But then, I dismount my chuck from the spindle using a knockout bar in the round insert hole, not with the Allen key in the hex gear tightening hole. I've never liked the idea of loosening the chuck from the spindle by way of the Allen key, even though that seems to be the only way on direct fit, insert-less chucks. It may be a baseless worry of mine, but I just think it may place undue stress or wear upon the moving gear parts in someway, where that knockout bar hole in the insert will never be negatively affected.I switched from Nova to Vicmarc last year.

Hello friends,
I have compiled a list of Vicmarc chucks/jaws that I'm considering purchasing. I would greatly appreciate your feedback and suggestions on my list before I make any purchases. Thank you

I have the 25mm pin jaws (VM120). I mostly use them for holding spindle blanks (3/4 ~ 1", square or round) and they're great for that. Plenty long enough to hold well. I'd probably be better for me to have the same size jaws on the VM100 just to lessen the knuckle-banging potential. But I didn't exactly choose them over the others, they came from an estate sale and you use what you have.Any words of wisdom with pin jaw buying and usage? I lean toward the larger 35mm version for the bit of extra length, but is the extra 3/8" diameter that meaningful considering most times these jaws would be used in expansion mode? Thanks.
