    I recently ordered the longworth chuck from Woodturner Pro, and the question I have, is how do you glue together/center closed rings to make say a bowl. I understand how I would center one ring, but how do I glue up subsequent rings, and keep them centered?? I have been feeling my way along, and do not have someone close by to teach me--so excuse my ignorance, but I'm a 58 year old rookie!

    Here’s what I did , I started by setting up a base with a plate chuck or the nova chuck then use the longworth on the tail stock put the ring on the longworth and clamp with the tail stock by cranking tight and let it dry long enough to add another, it’s not exact but it’s better than stacking, by the way I’m a 58 old coger myself lol

    I will usually mark the previous row with the centre of the segment edge length in four positions ( 0, 90, 180, 270 degrees) and then make sure they line up with the mitre line of the next ring. It is also important to keep the staggering going straight as well so each row stays lined all the way through the project. Sometimes by simply rotating the next ring to a different position can help get more exact.

    Blurr60, how do you mount the longworth onto a 2MT to mount into your tailstock. Mine has a hole in the center of it, I haven't measured it but it seems like it's around 7/8" so I just don't know how to mount the Longworth with that hole to a 2MT taper to put it into my tailstock...

    Oneway live centers can use an adaptor available that you can screw your chucks onto expressly for that. I got mine from a dealer at the Dalton symposium a few years ago, I learned it will not fit the copycat versions of the live center even though the thread count was the same, the machining was no the same depth and would not thread on. Resulted in me getting a Oneway live center and giving away the copycat, couldnt be happier as I use it centering pieces on my vacuum chuck to finish off the tenon.

    Thanks Gary, I have a oneway live center, so I'll look for something that will fit the longworth chuck!

    Do you know which one fits the Woodturner Pro longworth chuck??

    How do you mount your longworth chuck to your lathe? Normally you would get an adaptor to whatever size your lathe spindle is, then you can use anything you would normally mount for turning.
