chuck jaw question

GaryG in MD

For 4-jaw scroll chucks in compression mode:

I have collet chucks at 3/4" and below.

I have #2 jaws that go down to roughly about 1-5/8" minimum.

Sometimes I would like to hold a tenon in the 1" - 1.5" range.

I don't want to buy a huge collet chuck.

I have pin jaws that work, but they're very tall, and I'm not a fan.

I also have step jaws for small things in expansion mode, but they're tall too.

Is there such a thing as a "normal" #1 set of jaws that covers my desired range?

If so, who makes them and where can I find them?

What do you use?

Gary,

I have no idea what #1 and #2 jaws are. I don't see where you said what kind of chucks you use.

I use Nova chucks and have nineteen chucks at the moment with a variety of Nova jaws mounted so I don't have to change jaws. I keep multiple chucks with the jaws I use the most. I haven't found anything yet that won't fit in one set or another but I can't recommend specific jaws unless you use Nova chucks. I don't think Teknatool/Nova labels jaws as #1, #2, #3, etc.

I do have pin jaws I use a lot but they are not long. I use Nova's 25mm, 35mm and 45mm jaws a lot as well for smaller tenons. I don't know if all chuck brands are the same but the range of the jaws differs slightly depending on the chuck model since the slides open a bit further on some. (I have some of the G3, SN, SN2, and Titan chucks, mostly use the SN2) When turning something with a tenon I turn the tenon to fit the jaws I want to use since I want it to fit very close to the closed diameter for the most secure grip.

What kinds of things do you mostly turn and what brand of jaws?

There are 2 jaw sets out there that I love. The Vicmarc long nose jaws are tapered instead of straight out and very thick at the bottom. They hold from about 3/8" to a little over an inch.

Axminster has a set of jaws that are also extremely solid.

I use the Nova 35mm and 45mm spigot jaws for almost anything in the size range you mention. I agree fully with JKJ's comments.

I use the step jaws for my Talon.

They close to a squareish opening of about 1/4"

They stand off of the chuck body by about 1".

Handy for expansion too, but I use them on small finial blanks (usually pen blanks)

Each step is about 1/4 and has 'teeth' similar to the #2.

I have Oneway Talon and Stronghold chucks. For small items, I use the #1 jaws in compression. They work well up to about a little over an inch.

Gary not certain what you are trying to do but remember you can use the center of the jaws as a real small chuck. Particularly if you have a hollow center you can run a pretty small dowel through the jaw center or even set up a tenon. That is where the jsws come together at the center of the chuck inside the normal gripping jaws.

Thanks all!

Very good answers.

This gives me the opportunity to buy more tools! :-)

I'm sure one of these will do the job for me. ...GG
