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

Overview

Just rotate the plates of the Longworth Style Chuck and the soft silicone buttons close in almost instantly, and with perfect concentricity, 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 two sizes: the 10" Longworth Style Chuck for mini and midi lathes with a 10" swing, and the 16" Longworth Style Chuck for standard-sized 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, and turners work hard to make the bottom as beautiful as the top. But chucking a finished bowl face down on the lathe without damaging it has always been a challenge - not with the Longworth Style Chuck. 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. Note for heavy stock removal.
  • Note: Best practice for safety dictates that you engage the tailstock whenever possible. Remove the tailstock only when finishing the last bit in the very center, and for finish sanding.

Specifications:
  • Capacity in compression mode: 4-1/2" to 14" in diameter.
  • Capacity in expansion mode: 5-3/4" to 15-1/2" in diameter.

Excellent tool

Jerry Posted June 28, 2014
Pay attention to the instructions to avoid the two most common mistakes; improperly attaching the turning, and having the rotational speed too high. Both will result in your piece going somewhere you don't want it to go, however, that's why the instructions tell you all this. Yeah, it wasn't pretty.

Can't do better for getting the bottom cleaned up. Turn off the tenon, sand the bottom and clean up any mistakes you made on the sides. Remember to keep your fingers WELL away from the buttons. Of Course, the instructions tell you this too.

I bought the 16" unit and have to rotate the lathe head to get it to fit; probably should have paid attention and gotten the next size smaller. But the tool rest has enough reach to get over in place anyway.

Read the instructions, consider you're putting on a tire with eight lug bolts, tighten them in the "Star" sequence, keep the speed down and you'll really like this monster.

And, Order the replacement buttons when you buy the unit. There's a reason they are so readily available. The instructions will tell you all about it.
