The Best Wood Lathe Chucks (2026): NOVA G3, SuperNova2, Oneway Talon and More

The G3 wins on fit and ecosystem more than on any single spec. Nearly every jaw accessory sold for woodturning, from pin jaws for pens to wide bowl jaws and Cole jaws for finishing bowl feet, is made to the NOVA jaw pattern. Buy a G3 now and every jaw you add later fits it, and also fits Record Power's SC3 and SC4.

The G3 ships with standard 50 mm (2 in) jaws. For bowls, add a set of 100 mm bowl jaws or buy the kit below that includes them. If you are still choosing a lathe, our best wood lathes guide lists the spindle thread for each pick.

Bowl turning needs more grip area than the 2 in jaws that come on most chucks. The 4 in bowl jaws in this kit grip a larger tenon or expand into a larger recess, which spreads the load on a heavy, out of balance blank. The pin jaws handle small spindle work, pen blanks and drilling. That covers almost everything a new bowl turner does in the first year.

The insert version matters if you are on a mini or midi lathe today and expect to step up. When you move to a 1-1/4 in x 8 TPI lathe, you buy the NOVA ILNS insert (about $31 at the time of writing) instead of a new chuck.

NOVA G3 vs SuperNova2 comes down to lathe size, not quality. Both are four jaw geared scroll chucks from the same maker and take the same jaw pattern. The SuperNova2 has a larger body and more jaw travel, and Teknatool's guidance puts it on lathes with 14 in to 20 in swing, while the G3 is meant for lathes up to about 16 in. Dealers list SuperNova2 capacity with the standard 50 mm jaws as bowls up to about 12 in and spigots up to about 6 in long; larger bowls call for its 100 mm or 130 mm jaws.

Inserts for it: NOVA ILNS 1-1/4 in x 8 TPI (about $31), NOVA IDNS 1 in x 8 TPI (about $27), or NOVA I4NS M33 x 3.5 (about $30).

Chuck key vs tommy bars is the real decision here. A key drives the scroll through a pinion, so you can hold a bowl centered against the jaws with one hand and tighten with the other. Tommy bars need both hands, one on each bar, which makes remounting a finished bowl a little more awkward. Turners who do a lot of reverse chucking usually say the key is worth it.

Oneway notes that its full size chuck and the Talon share jaw compatibility, but the Talon's smaller body changes the capacity overlap. Check the jaw chart before buying extras.

The SC3 sits between the G3 and the Talon. You get key tightening like the Talon, and you keep the NOVA jaw pattern like the G3. The woodworm screw is the fastest way to mount a bowl blank for roughing: drill a hole, thread the blank onto the screw, turn the outside and a tenon, then flip it into the jaws.

For small work, more jaws matter more than a bigger chuck. The step jaws and pin jaws hold pen blanks, stopper blanks and small dowels the standard jaws cannot. PSI's manual recommends turning at 500 to 1,500 rpm, using slower speeds for larger work, and leaving at least 3/16 in of grip on a 2 in diameter tenon or recess.

For bigger bowls on a PSI chuck, PSI also sells #3 wide bowl jaws for its Insta-Change chucks (about $39). Check jaw compatibility with your exact PSI model before you order.

A budget chuck is fine for learning, and a G3 is the upgrade most turners end up making. If you go this route, keep blanks small and balanced, keep speeds low, and check the jaws stay tight after any catch. VINWOX sells wide jaws (about $19) for its chucks if you want more bowl grip later. Need turning tools to go with it? See our best woodturning tools guide.
