The only way to go!

Comments On May 05, 2020:I really like the Modern Longworth Chuck! It's a great timesaver and a well built unit. So much easier and quicker than changing out the Cole Jaws I have been using on my 4 jaw chuck. Great quality unit and you can't go wrong here.

Good product, extra benefit

Comments On Dec 13, 2016:I have used this several times to finish the bottoms of bowls and it worked just fine. I also use it to center segmented rings when gluing section to section, a really nice "unintended consequence". So it is a great product, high quality components, well worth the money to me.

RMWoodco Longworth Chuck

Comments On Nov 12, 2015:I bought this chuck after my shop made Longworth finally died after using it for 10 years. The RMWoodco unit is very precise and has a metal center hub for grabbing with your chucks jaws... this makes it very easy to install and un-install.... saves time vs the plate design of my shop made unit.
In summary this unit is a nice upgrade for me
I give this a 5 star rating

Difficult to re-chuck

Comments On Feb 03, 2015:Works well when finishing off a bowl bottom but if you have to re-chuck and the bowl has a moderate diameter it's very time consuming to get it centered. You have to tighten opposing posts small amounts at a time and if you're using the knurled nuts, you can't get them tight enough to keep the bowl in place. I prefer the cheaper, easier to use and more secure Cole jaws.

Sure beats the cole chuck!!

Comments On Jan 27, 2015:Received my Longworth chuck this morning. I had four bowls that needed finishing off on the bottoms. First thing I did was to read instructions, check it for all parts, & then watch that accompanying CD. I went back out to the shop and swapped out the knurled nuts for the wing nuts (also supplied). I then chucked up a 12" fruit bowl (piece of cake). Finished off the bottom, sanded & applied finish. GREAT PRODUCT!!!!! I then did three more bowls. I had a Cole jaw several years ago, but wasn't happy with them. I fully recommend the Longworth chuck to anyone from beginner to professional wood turner.

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.
