I’m about to receive a new G0733 wood lathe and am looking into chuck options. It’s reversible and has a 1-1/4” x 8 TPI spindle. I can’t seem to find a reversible chuck that supports this spindle threading, looking for recommendations.

The chuck I’ve been using on my old lathe is a PSI Barracuda (CSC3000C), and I have an adapter to make it fit the new 1-1/4”x8 spindle but it’s not reversible.

Pretty sure there’s a Nova G3 Pro-Tek with those options. Call Teknatool and they’ll tell you for sure. I don’t recall whether there’s an adapter in the mix or not, as I have 1×8 threads on my Harbor Freight midi.

The SuperNova bundles have the reverse turning set screw. They also have dovetailed 50mm jaws. The Nova 23108 Premier Pro-Tek Supernova 2 Chuck Bundle with Pro-Tek 2” Jaw Set is the set I bought that has them. I had to specify the 1 1/4×8 tpi adapter for the chuck. They are not inexpensive but no regrets here especially with the dovetailed 50mm jaws.

Interesting options, thanks. None of them come direct threaded for 1-1/4×8 tpi, but it looks like it might be an option on the “insert thread” models. Is it better to get an insert thread for 1-1/4×8 tpi, or use an external adapter on the 1×8 tpi direct threaded chuck?

The options on the nova “pro-tek” page are:

48290 NOVA PRO-TEK G3 INSERT THREAD CHUCK & JAWS
48291 NOVA PRO-TEK G3 DIRECT THREAD 1″X8TPI REVERSIBLE CHUCK & JAWS
48293 NOVA PRO-TEK G3 DIRECT THREAD 1″X8TPI REVERSIBLE CHUCK BUNDLE
23108 NOVA PRO-TEK SUPERNOVA2 INSERT CHUCK BUNDLE
23262 NOVA PRO-TEK SUPERNOVA2 INSERT CHUCK & JAWS

Based on the description, it looks like only the “G3” model has reversible options.

Thanks Tony, that’s an interesting alternative. Would have to get a vacuum chuck though.

The external adapter may add a bit of run out as it will add some lenth to the chuck assembly. That means it will shorten your center to center length. The Nova 23108 Premier Pro-Tek Supernova 2 Chuck Bundle is reversible, it has a grub screw/set screw that secures it to the spindle. I wanted a direct thread chuck but the Supernova has been great.

Thanks for the info, wanted to make sure the model was correct. Wish their website had this information listed, or even just some better pictures. Might order the 23108 since I don’t want to deal with run-out as you say. Does it come with several inserts, or do you need to order a specific insert for your spindle threading?

I have a supernova 2 and a G3. I prefer the G3, as it seems to hold better. The SuperNova creeps a little on me, but that may just be that it needs a rebuild (I bought it used).

In that bundled set you select the size insert you want for your particular lathe.
I ordered mine on Amazon from the Nova store.

The Oneway chucks also have a set screw to lock them on for reverse turning. I have both a Talon, and a Stronghold chuck.

Looking at the adapter for vicmarc chucks, they look to have the set screw hole too.

Are any of these chucks not Chinese-made? Would love to have a German or US one, despite the premium price.

Edit:

Nova: unclear origin, may be Chinese or from NZ
Vicmarc: made in Australia
Oneway: made in Canada

I have the Oneway stronghold and talon chucks great lathe chucks. I use the supernova at my woodworking club shop sometimes but use my own most of the time at the club shop. The supernova because of the use it gets at the club shop needs repaired occasionally due to the high use.

So I found the same info on country of origin for Vicmarc and Oneway. but did not see anything on Teknatool web site.
So funny, just now I was taking some photos of my chucks to show what they use for a set screw to lock them for reverse turning. and noticed my Supernova 2 chuck says made in New Zealand on the back of it.

Here are photos of the chucks showing the set screw location on the adapter.
I have only ever used this on the Oneway Stronghold chuck. Not a feature I use much.
The Supernova is my newest chuck. $50 craigslist find a few months back, I could not pass on. and never compared the adapter to the Oneway chucks before, but the set screw is very small on the nova.
And the Oneway can accept two set screws.

These are all 1-1/4”x8 chucks. the two on the bottom are Oneway Stronghold, and a Talon chuck.
Top is the Supernova 2

This last photo left to right, has the Stronghold, Supernova,and a Vicmarc VM100 clone I got from Grizzly. My 1st chuck, and it has no set screw option. Not sure about a real Vicmarc.
The purpose of this photo is to show the jaws. I have only had the Supernova a few months, and the jaws came with it. they have a dovetail, but notice how thin they are compared to the other two. I have not had a problem with this. And the chuck runs true. Just a little surprised at how thin they are.
So a question for the group, are all the Supernova jaws this thin? or is there something special about this set?

Bob, I hope all the info helps you out,
Good luck.
