Great for bowl tenons after using a Kelton to core

Comments On Aug 28, 2013:1. You should look at the instructional videos from RMWood. 2. You need to use this chuck in-line with a tailstock. It can not be used for outboard turning. On my Nova 1624 I use the 16" chuck. Reason: the chuck is mostly supporting and lightly gripping the edges. In case the bowl shifts out of the chuck you want something else to constrain the bowl. If I don't have the tailstock supporting the foot of the bowl then I have the tool rest almost tight to the foot. I also got two of the ring sets to help support edges that aren't square.
I use this chuck to: a. Make the tenons on bowl blanks I have cored with my Kelton coring tools. I never can get jamb chucking to work for me. b. Finishing the foot of a bowl. If you have oiled the bowl, or it is light colored wood, you might want to put plastic wrap or a clean rag on the edge to protect against the bumpers leaving a mark. They aren't supposed to leave a mark according to RM but it has happened to me. To tighten the bumpers, and save my fingers, I use a push drill. A single push alternating bumpers the first time. Then a single push on every one until they are tight. This saves me counting 4 turns of the wing nut. To loosen the bumpers I use a drill since I am not trying to slowly apply equal pressure all around.

16" Longworth Chuck

Comments On Oct 24, 2012:I had some difficulty with the chuck at first, but I was referred to RMWood and received excellent support. I've used the chuck on a number of bowls for turning a more professional bottom than sanding off a nub and this chuck worked great.
If you don't turn daily and/or have only one lathe, this chuck is a quick change-over at a much lower price than a vacuum chuck. And because of the way it adjusts, it only takes a minute or two to set the bowl in place, without centering with a tailstock even. I would recommend this chuck for a small shop.
