chuck jaws
chuck jaws
I have a old South Bend 9" lathe. it came with a Skinner 6" chuck and the jaws to hold work from the outside.
I don't have the other inside jaws. Can those be obtained somewhere?

Re: chuck jaws
Probably not. Almost certainly not new. Try ebay and related. You may well need to buy a whole new chuck - which may not be much more expensive than just jaws.

Re: chuck jaws
Depending on what you do with your lathe you may consider
If you only have one chuck is should be a 4 jaws independent
If you rather have only one scroll chuck is better to swing for a two pieces jaws rather then reversible. It gives you the option of using soft jaws.
On the other hand a plain scroll with 2 sets of jaws may suite fine.

Re: chuck jaws
Lewayne, Take your outside jaws and get a good set of measurements off of them....then look on Ebay. Wait long enough and eventually a set of jaws will show up. I was able to do this and find a set of jaws for a 12" chuck I had. On the other hand you may want to just purchase a good chuck with 2 piece jaws. That would allow you to not only reverse the jaws, but also use machinable jaws, which would be much more versatile.

Make some measurements and put up some pictures, preferably with the measurements on the picture.
I MIGHT have a set. There were some outside jaws in my dad's toolbox, and he sold off the South Bend 15 years ago,

Re: chuck jaws
Finding a small enough chuck with 2 piece jaws may be a real challenge. The 6" 4 jaw chuck that came with my 12" Atlas weighs 8# and the 6" SHAR chuck with 2 pc jaws weighs 26#. Way too heavy for the Atlas.
You might try Small Tools in Euclid Oh. Last summer they had a skid load of Chinese 5" chucks with 2 pc jaws. I didn't get the price.

You might also ask them if they have the missing SB jaws you are looking for. Good Luck

Re: chuck jaws
SteveM check if you have a chance. I have a 7" chuck, set up for that operation, which I found on e bay cheap once. Its a bit big on my 9" lathe though.
I've been cleaning the rust off that one this weekend. It came that way and I never got around to cleaning it up. That one could use a new base plate as well.

Re: chuck jaws
I have a 6" chuck with 2-piece jaws, and I don't think it's anywhere near 26 lbs. It works fine on my Atlas (as long as I don't hit reverse, then it can unscrew).
An option if you can't find the outside jaws is to find a chuck that is missing the INSIDE jaws.
As the outside jaws are generally used less, you will probably be able to get it cheap ("hey, I'll give you $50 for that chuck - it's missing the inside jaws!").
The nice thing is that you no longer will have to unscroll your chuck to swap jaws - you just need to swap chucks.
I have a chuck with only outside jaws just for that.
I have THREE four-jaw chucks, one with the jaws inside, one outside, and one with two of each. I haven't unscrolled a set of jaws in years.

Re: chuck jaws
I do not mind swapping jaws, but I do not relish swapping chucks.I haven't unscrolled a set of jaws in years.
I made chuck socket drivers to fit all my chucks. The drivers fit the 1/4" hex of my power screw driver.
Swapping or reversing jaws is a snap.

Re: chuck jaws
I'm going to make one out of one of those power screwdrivers one of these days. Just need to find a working one at a garage sale because I'm too cheap to buy a new one.tornitore45 wrote: ↑Mon Feb 04, 2019 2:23 pmI do not mind swapping jaws, but I do not relish swapping chucks.I haven't unscrolled a set of jaws in years.

Re: chuck jaws
So I cleaned up the chuck I have with the inside jaws. It actually is a Japanese chuck and is 6 1/2". I thought it was 7" IT cleaned up really nice so I guess I have a separate chuck for each application. maybe a pain to use sometimes but I only paid about 50 bucks for the larger one. I have a little 4" 4 jaw that I found cheap one time.
So the 6 1/2" has a 6" backer plate and I guess the bolts need to go into the outer ring of the chuck. not anywhere inside the back? am I right?
Someone has placed the bolt holes right on the edge of the backer plate and done a very poor job of it. There's not much metal under the bolts. Only a thin shoulder. Not a full round hole either. My feeling is it could come off the backer plate and become a loose cannon, so to speak.
Can I easily find a raw blank with the hole already threaded for my south Bend? I think the end is 1 3/8' with 8 threads per inch. (thats from memory though). I saw some in a catalog on line, but it was too late to call and clarify what all their numbers meant. If the threads were right it looked like I could turn a larger one down to 6 1/2 and place new holes in the right place.
