Longworth Style Chuck

Add the finishing touches to the bottoms of your bowls and platters with minimal setup time!

Item #
78% of 100

Just rotate the plates of the Longworth Style Chuck and the soft silicone buttons close in quickly to hold your project while you make the finishing cuts to the bottom side. Unlike many other rechucking methods, the silicone buttons won't mar your project or your finish. When compressed with the wing nuts, they expand to provide a secure grip. The 1/4'' thick phenolic plates provide strength and stability, regardless of humidity. Available in the following sizes: 10'' and 12'' for mini and midi lathes, and 16'' for lathes with a 16'' swing or larger.

Pick up a piece of fine china, and the first thing you'll do after admiring the face is turn it over to inspect the bottom and insignia. It's no different with turned bowls, so turners work hard to make the bottom as beautiful as the top. With the Longworth Style Chuck, securing a finished bowl face down on the lathe without damaging it is easy. Simply rotate the plates, tighten down the buttons, and you're ready to turn.


  • Eliminates the time and inconvenience of installing, adjusting and readjusting ordinary rechucking jaws
  • Capable of holding projects in compression or expansion mode (from the inside or outside of the rim of your turning project)
  • Buttons close in concentrically, making it easy to center your project
  • Soft silicone buttons have increased length for better grip and expansion capabilities
  • Buttons expand when the wing nut is tightened, and will not mark or deform your turned piece
  • Includes 8 buttons. Replacement packs of buttons with hardware are available separately (#47455)
  • No assembly required
  • 1/4'' phenolic discs are extremely durable, stable, and spin in opposing directions with almost no resistance
  • The back side of the Longworth Style Chuck has a steel disk approximately 3/8'' thick for mounting
  • The disk is easily gripped by any brand of 4-jaw scroll chuck with the standard 50mm #2 jaws
  • Straight jaws may be used, but dovetail jaws provide a better hold
  • The dovetail groove accommodates Nova chucks and Vicmarc chucks as well as OneWay type straight jaws
  • Recommended maximum RPM is 600
  • Intended for light finishing cuts only—NOT for heavy stock removal

What a piece of garbage!!
Do not buy this! It will not hold your workpiece not matter what you do or how tight you wrench the nuts down.
Very disappointed in the product and will never consider Ron browns best again cause everyone else’s worst is better than his best.

Woodworking Experience:
Not safe to use
I noticed there was a one-star review on here, and I thought it unjustified... until tonight.

I have not finished many bowls with this. The first time I used it I didn't have the posts cinched down tight, so my bowl flew off. The second bowl (a few days ago) I had everything cinched down tight, and I was able to finish the bowl adequately. Tonight I had everything cinched down tight, and as I was turning the tenon off, the entire thing came off my lathe! The point of failure was the 4-jaw chuck gripping this chuck. It is, as the previous review pointed out, quite weak as the chuck can barely grab the tenon on the longworth. In this case, the failure was catastrophic to the chuck. One of the posts bent almost to a 90-degree angle, and part of the longworth itself snapped. I can't in good conscience recommend this product.

Woodworking Experience:
not safe to secure with 4-jaw chuck
Two of the 20 times i used this chuck with the tailstock holding tight against a bowl, the steel mounting plate slipped from my 4-jaw chuck with #2 dovetail jaws. While i like the smooth counter-rotation of the chuck plates, and effective hold of the 8 mounting screws, overall rating is Not Acceptable. See attached pic that shows how dovetail jaws BARELY grip the mounting plate. Need to replace the mounting plate with a threaded faceplate.

I presume the stated size of the chuck is the diameter, not the required swing of the lathe? i.e., a 12" chuck would have an approx swing of 6"?
Robert on May 28, 2019
BEST ANSWER: Yes. i bought a 16" diam that fits my lathe with 8" swing.
