I bought a set of 100 mm jaws for my Supernova chuck but after doing the changeover tonight to use on a bigger bowl I realized that swapping jaws in and out is kind of a pain in the behind. Do most folks have a chuck for each jaw size?

Yup! ... I do. Eleven 4-jaw chucks and even more jaw sets from 6 different brands. The first was the Nova with tommy bars (1990) which is vary rarely used anymore. The latest purchased was 2 weeks ago and not yet used. A Record SC2 - boy, that's a little chuck - only 2-1/2"Ø.I bought a set of 100 mm jaws for my Supernova chuck but after doing the changeover tonight to use on a bigger bowl I realized that swapping jaws in and out is kind of a pain in the behind.

Well one will do. It is sort of a luxury to have multiple chucks. I used to have one chuck a long time back.Chucks are definitely not cheap. A bare SuperNova with insert is $170. I wonder if it make more sense to get a bare G3 for the 2" jaws and use the 4" on the Supernova I already have.
Edit- - scratch that... the G3 chucks use a different style wrench.
That's a very good point, thank you!Well one will do. It sort of a luxury….
When you get into using different jaw set you can often be more efficient changing jaws less often
When I turn hollow ball Christmas ornaments I turn balls with #2 jaws, finials with #1 jaws
I can turn a ball switch jaws turn the finals repeat or
Use a more efficient process
Turn balls one day(s), Change jaws, Turn finals 1 day.
It is somewhat rare where you would be swapping jaws more than once a day.
I think you need to seek medical attention for a serious GAD infection. Gear Acquisition Disorder can empty bank accounts, make SWMBO really mad, and limit effective shop organization.I have over 40 chucks but someone told Pat Carroll that they had more. About half are Novas the rest being Vicmarc, Oneway, Bulldog, Axminster and a few secondary branded chucks.
Does anyone else use a power driver to change jaws? I've been doing so all along, with an cordless impact driver loaded with an Allen key.
Nope, never. Hand tighten & hand loosen.Does anyone else use a power driver to change jaws?
No - it would never have even occurred to me. Hand tightening ought to be adequate.Does anyone else use a power driver to change jaws? I've been doing so all along, with an cordless impact driver loaded with an Allen key.

Thanks Dean, that seems like a good plan!David,
If I am understanding your situation correctly, with the size lathe I believe you are working with, you should not have a need to change jaws. You can do any bowl or spindle in your capacity with the 2" jaws that came with the chuck. If you start turning bowls or hollow forms of >12" diameter, you may need to move up. But for now, just leave one set of jaws on the chuck and make all your tenons the same size. KISS
Thanks, so now you have four chucks and swap jaws as necessary?I was one that hated removing the screws to change jaws. I had 9 Nova/Record chucks all with different jaws and sold all of them and bought two Axminster chucks. I had two for a long time, but when Lee Vally closed out the brand I bought two more bodies, a luxury. It is so much easier to crank out one set of jaws and in another. I also have the O’Donnell jaws that replace many of the special jaws. You need to store chucks someplace, much easier to store jaw sets. Much happier with the chucks I now have.
I also have four Supernovas and one Titan. A few days ago a neighbor had a cherry tree taken down and offered me the wood. As Jim described, I used the Titan to hold four of the 9 blanks I got while I cored them with the McNaughton (which I’m just beginning to feel competent with). Having multiple chucks made it easy to quickly turn the cores I got out of the largest blanks without constantly removing and remounting jaws. In total I rough turned 17 bowls from the 9 slabs. If the Titan jaws could hold a woodworm screw, my process might have been slightly different.I have 2 Supernova 2 chucks for 2" and 4" jaws. Now looking at 5" jaws and will likely go for the Titan III so I dont have to chane jaws when coring larger bowls
Yes, that is correct. With the Axminster chucks you buy jaw slides in addition to the jaws. You mount the jaws on the slides only once. Still cheaper than buying a whole chuck for the jaws.Thanks, so now you have four chucks and swap jaws as necessary?
Hmmm ... my Titan II came with a long woodworm screw, which I have used several times.If the Titan jaws could hold a woodworm screw, my process might have been slightly different.
You’re right Gerald. I should have been more specific. I’ve got the deep Power Grip jaws on the Titan III chuck and the screw that came with it is not long enough to use with those jaws, yet too long to use with standard jaws without a spacer. The attached thread I posted when I got the chuck details my effort to figure out if there was a way to use the woodworm screw with the Power Grip jaws, including communication with Nova.Hmmm ... my Titan II came with a long woodworm screw, which I have used several times.
Yes I found the same thing with my stepped jaws , have been contemplating modifying them, just havent quite decided which way to go on the modification.Worst set of jaws that I never use, the stepped jaws. I guess they work for tenons, but you can't get to the bottom if you use the small tenon setting.
And I will repeat, the driver drills work great for removing and replacing the screws, IF, and only IF you adjust the clutch down. The newer versions do not have clutch settings on the screw guns, so very careful 'feeling' how much it is torqueing is essential if you don't want to have stripped screws and screw holes.
