I introduced the new chuck at the AAW National Woodturning Symposium in Hartford, Ct. in June, 2010. 

The New Longworth Style Chuck is available in nominal lathe sizes to fit most modern wood lathes: 10", 12", 14", 16", 20" and 24" with prices beginning at approximately $139.95 plus shipping.

How To Order Your Longworth Chuck:

You may order directly from me further down this page, or check with a woodworking retailer near you. Sizes listed indicate the swing of the lathe.

The modern version utilizes a steel disk approximately 3/8" thick for mounting. This disk is easily gripped by #2 jaws (optional 4" disk available for use with #3 jaws). It is extraordinarily easy and quick to mount and costs about the same as a quality set of Cole/Bowl jaws with similar capacities. Imagine, no more changing chuck jaws or moving buttons.

There is a dovetail groove to accommodate Nova Chucks and Vicmarc Chucks as well as OneWay type straight jaws. I haven't found a chuck yet that the Longworth would not fit.

The New Longworth Style chuck uses soft rubber buttons which are longer than most others. They gently compress and will not mark or deform your turned piece. Intended to hold your item securely while finishing the bottom, the recommended maximum speed is 600 rpm.

 

To request more information and prices, scroll down.  You may request a PDF copy of the instructions for the New Longworth Chuck here.

Imagine!

  1. Never moving buttons again!
  2. No need to change jaws to use this chuck
  3. Fast, Fast, Fast!!!
  4. 3 minute change over from hollowing inside to finishing the foot
  5. Never have to remove the "Black Rubber" marks left by your Cole jaw buttons
  6. Works with any standard chuck using #2 jaws (or optional #3 mounting Disk), OneWay,  -Nova, Vicmarc, Barracuda, Penn State Ind., etc.
  7. Works with any lathe from 10" (mini lathes) up to 24" swing Robust, Powermatic, OneWay, Serious, etc.

How to Get Your Own Longworth Chuck

You may order directly from me just below. Sizes listed indicate the swing of the lathe.

Example: 16" Longworth Chuck will clear any lathe indicating a swing of 16". The chuck is actually just less than 16" (approximately 15-3/4"). You may also use it on a Powermatic 3520 with a 20" swing, but not a Jet 1442 which will only swing a 14" chuck. A Jet 1642 will be fine.

12" Longworth Chucks will fit all lathes with 12" indicated swing.

Notice:

All Modern Longworth Chucks have very soft tapered buttons which will not damage your bowl. They expand as you tighten each wing nut. We strongly advise that you utilize the tailstock against the vessel as long as possible when using your Longworth Chuck.  1) This will trap the bowl so it doesn't fly out and shatter, 2) It will eliminate any possible vibration giving you a smooth cut, 3) Best Practices dictates for safety that you engage the tailstock whenever possible.

Remove the tailstock when finishing the last little bit in the very center and for finish sanding. At all other times, use the tailstock.

This means that if you have a lathe with a pivoting head, that you must work over the bed to utilize the tailstock. Think of a Jet 1442, or a Nova DVR300, etc.

NOTE:

For all 20" & 24" Longworth Chucks with the 4-1/4" mounting plate, dovetailed jaws are required for use in your 4 jaw woodturning scroll chuck in order to hold your Longworth Chuck safely. Using the dovetail groove in the 4-1/4" mounting plate is important in achieving the proper grip. Remember that all woodturning chucks hold tightest when almost fully closed.

Nova Titan Chuck.

I recently received the following letter regarding the 20" Longworth Chuck and the proper jaw set.

Ron,

Hi. This is Mike ..... (again!). I contacted you about 10 days ago about my difficulty finding the correct set of NOVA jaws to fit the 20" Longworth. ..... We were both concerned that Novas 100mm jaws could be too small and the 130mm jaws might be too big. Well, I thought I'd let you know, in case someone else asks, the 100mm jaws won't work (or fit) at all. The 130mm jaws work perfectly and grip tightly (with about 1/8" to spare) Hope this info helps. I haven't had a chance to use your Longworth style chuck yet, but it does look good !

Thanks,

mike

Vicmarc 120

I use the 128mm jaw set part #vo677 with my 20" Longworth Chuck and it is perfect.

Longworth Chuck Suggested Tightening Sequence

1) Finger Tighten each button bolt assembly off the lathe using this sequence to maintain concentricity.

2) Mount the Longworth Chuck with vessel into any typical 4 jaw wood turning scroll chuck installed on the lathe per instructions.

3) Take three full turns (6 half turns) on each button. Over-tightening will result in split buttons.

4)  Bring up the tailstock against your vessel to eliminate any vibration and leave it there until you have just a small nub at the center.

5)  Back the tail stock away and carefully remove the nub. Sand and finish per usual on the lathe.
