|Tips: Easy Tenon Measuring|
Easy Tenon Measuring
After truing the ends of your turning blank between centers, you can mark to cut a tenon for chucks with #2 jaws on JET 10" × 14" (25cm × 36cm) and 12" × 20" (30cm × 51cm) mini lathes by placing a pencil atop the tailstock, then touching the spinning wood.
A pencil mark from top center of tailstock will produce a mark slightly larger than 17⁄8" (48mm), which is the largest tenon that will fit into the Tekna-Tool Nova midi chuck.
Marking from the top flat corner of tailstock will produce a line just over 21⁄16" (52mm) for a larger tenon to go into most other chucks.
If you cut the tenon a bit smaller, it will still fit into your chuck. This pencil trick works on my 3520 Powermatic also. Check to see if this will work on your lathe.
