"Each jaw is independently adjustable, but all 4 can be moved together via a scroll mechanism."
I don't see the advantage of the scroll. Do you use it just to bring the jaws up close to the work then adjust independently? Seems expensive to save 20 seconds. You certainly couldn't use it as a scroll chuck without checking the alignment each time.

Anyone notice the "new" Bison combination chuck in the New England Brass & Tool ad in HSM? Looks like a miniature version of the chuck on our F E Reed lathe at Tuckahoe Steam & Gas Association. That lathe is ca. 1899, and we think the chuck is original. Pictures at http://home.comcast.net/~TuckahoeMachineShop/Index.htm
I wonder if the independent adjustment range of the jaws is the same as for an independent chuck.

Geez, that's gotta be hell to get back in alignment. I've got a 4-jaw "faceplate" that looks similar to that. The slots on mine are radial between the jaws though. 11 1/2" I think.

Nice looking Lathe you guys have. I have a similar F.E. Reed in my storage trailer waiting for they day I build a garage. It does not have a compound rest & The gear train for the carrage feed is slightly different, but still uses the three step belt. My apron controls are a bit different as well. I love those old cone heads & love to see one inoperation. Thanks for the link interesting place you have there

I'm missing something here. Why would this kind of chuck be any harder than a normal 4-jaw to get lined up right? Thanks.
