About Tooling

Drill

Each kit has the necessary drill listed under "tooling"

Bushings

Each kit has the proper bushing listed under "tooling". Please note: The bushing designation is a number followed by the letter A or B. These letters tell you the mandrel shaft you will need to make the kit.

Mandrel Shaft

Each kit lists the correct mental shaft under tooling. It will either be a (about 1/4" diameter) or B (larger, at about1/3" diameter). You can also tell by the letter on the bushing (see bushings). We recommend the precision mandrel shaft.

Arbor

(Holder for the mandrel shaft)
This is the tool that the mandrel shaft screws into and then goes into the MT hole in the head stock spindle. The Precision System arbor is recommended. These come in two sizes—a MT#1(Morse Taper #1) and a MT#2(Morse Taper #2). These fit into the hole in your head stock spindle.

Most current lathes have either a MT#1 or a MT#2 hole. Many of the mini lathes have a MT#2 hole (Jet-Delta etc). To determine the MT hole size consult your manual. If this is not possible measure the diameter of the hole-less than a ½”= MT#1—over ½”= MT#2 IF YOUR LATHE DOES NOT HAVE A MT HOLE THEN YOU MUST USE A DIFFERENT METHOD.

The different method is usually a drill chuck or a three jaw chuck. SHOP SMITH OWNERS WILL USE A DRILL CHUCK.IN ALL THESE CASES YOU MUST USE THE HIGH PRECISION MANDREL SHAFT AND WILL NOT USE AN ARBOR.

By "tooling" we mean: 1. The proper drill 2. The correct bushing
