The B4 Ball Positioner and the original JR-100 Universal Work Positioner are two outstanding Work Holders.

B4 Ball Positioner (JR-B4LC)
The B4 Ball Positioner is a substantial tool – plated steel, precisely engineered and well finished. It can be fixed to your work bench or made portable via an optional steel plated table clamp. The 2.5″ diameter ball rotates very smoothly a full 360 degrees.
“The circular clamping rings take a massive bite on the ball… this is a beautiful piece of equipment, made with a lot of care and attention. It is hefty, versatile and will serve well for a lifetime of hard use” – Chris Pye

Features:

  • Optional table clamp makes B4 and JR-100 portable from one workbench to another
  • All steel and plated – Super strong and heavy duty!
  • Clamp opens to 2 inches at bench and locks firmly with handle
  • A large comfortable handle allows the user to quickly lock and unlock the clamp
  • Tightens easily to a workbench
  • Weight: 10 pounds

Here is what Woodcarving Illustrated Magazine said about our B4 Work Positioners.

“At last, there is a completely flexible holder that puts the work exactly where the user wants it! Because it is fully 360 degrees rotatable (not 90 degrees as with other makes) it can be tightly locked in any position that’s comfortable for the operator while providing full access to the object.”

“The B4 allows processing above or below the workbench – with the user standing or seated. What’s more, the workplace can be positioned so that any side or surface is exposed without the need to disassemble. The swivel ball unit can be reversed onto the foot, which increases the mounting possibilities.”

“Any carver working three dimensionally should have a work positioner, and this one is as good as they get!”

Accessories are available for Wood Carvers, Wood Turners, industry, medical, sculpture, guitar and stringed instrument building and numerous other areas. Regardless of size, if you need it held and positioned, we do it best!

Tapered Carving Screws (small: JR-CSM) (large: JR-CSL)
Our Tapered Carving Screws are a better alternative to the conventional carving screw. The tapered part of the screw is turned into a pre-drilled hole in the base or back of the carving and tightened by using the hole in the “T” handle. The “T” handle, can be threaded onto the screw until the work is pulled tight against the bench. Rotate the carving by loosening the wing nut and position the carving, then tighten again. No need to drill a deeper hole like conventional carving screws.

Features:

  • (JR-CSM) 6.75” for small to medium carvings
  • (JR-CSL) 9” for larger carvings
  • High quality construction with cadmium plating on the screw, holds more tightly than a straight screw
  • Rugged “T” handle wrench, for driving in the screw, is black powder coated for protection
  • Plastic tips on the “T” handle wrench for safety and easy gripping
