The tenon is for mounting to a Scroll Chuck and the 3/4- 10 inserted nut in the tenon isfor mounting to a Live Center with removable cone or our OPTIONAL MT2 Chucky Arbor. See below for more information.
The Original Rubber Chucky was designed to use with Hollow Forms; but it can be used with any item you see fit.
The dimensions of the Original Rubber Chucky are 4" at the base, tapering to a 1/2" diameter at the tip and 3 1/2" tall (the tenon height is not included in this dimension). These dimensions are approximate as each chucky is hand finished.
We do recommend ordering the optional 3" MT2 Chucky Arbor to fully utilize this product. However, if you already own one of our Chucky MT2 Arbors, it will not be necessary to order another as it is interchangeable with all Rubber Chuckies. However, the arbor is necessary if you wish to turn a dovetail on the tenon.
NOTE: The Arbor has a 1/4" X 1" hole in the threaded end to accommodate items mounted on a 1/4" shaft such as sanding disks, buffs etc. It also has a 1/4-20 threaded hole in the taper end to install a draw bar.
