The VersaChuck Model 'T' is an 80 mm diameter, four-jaw, self-centring, scroll chuck designed for use by woodturners,
especially those using smaller lathes. As a rough guide, these will be lathes with a "swing" (diametral capacity) of up to 12" (300 mm). The chuck will hold larger workpieces perfectly adequately in the
right hands, but this is a guide for general use. Matching the spindle threads routinely found on lathes of this type, the Model T is supplied with a choice of
either 3/4" x 16 tpi or 1" x 8 tpi mounting bushes. Like old Henry Ford's original Model T, our tribute to the name is a chuck designed to be both affordable for all lathe users and yet being practical,
versatile, robust and reliable in operation - a joy to own and use.
A bush screwed into the rear of the chuck body carries the spindle mounting thread, allowing the chuck to be adapted
to fit onto a variety of lathe spindles. The model 'T' is supplied with two sets of workholding jaws, each set featuring serrated gripping surfaces (typically know as "gripper jaws"), designed to give
an excellent grip in both compression and expansion mounting modes using parallel-sided recesses or spigots. Such recesses and spigots are much easier to create than an accurately matched dovetail recess or
The chuck is operated by the use of two tommy bars which are inserted into holes in the chuck body and the operating ring, respectively. Unlike most other tommy bar-operated chucks
on the market, the Model T boasts four tommy bar holes in each ring so that the levers are never more than ninety degrees apart: in turn this means that any but the most petite-handed operator
can grip both tommy bars in one hand to either nip up or release the chuck's hold on the workpiece. This simple bit of design originality means that you still have one hand free to hold the
workpiece whilst operating the chuck with the other hand. (Our apologies to all of those triple-handed users that this may now render obsolete - along with their ill-thought-out chucks!!!)
- 80 mm (outside diameter) scroll chuck. A set of workholding jaws is mounted on the chuck, as delivered, with an internal (compression) grip of 38 mm (1.5") and an external (expansion) grip of 50 mm (2")
- A second set of workholding jaws with a 15 mm internal grip and a 25 mm (1") external (expansion) grip, plus a further 1.5" (38 mm) external (expansion) grip step useful when
turning hollow objects such as boxes.
- Mounting bush to suit lathe spindle, ¾" x 16 tpi or 1" x 8 tpi threads only.
- Two tommy bars, which are used to operate the chuck.
- Allen key for workholding jaw removal and replacement.
- User Manual and Operating Instructions.
ScrewChuck Accessory: A generously-proportioned screwchuck is also available, which is secured in the chuck by the mounting jaws of the Model T chuck, giving
a sturdy "first-fixing", particularly suitable when bowl-turning. The screw is 12.5 mm diameter and features a slim cross-section thread form to minimise
disruption of the timber as it is screwed into place, whilst also easing the passage of the thread through the workpiece. The screw is gold passivated for improved corrosion resistance.
