All mandrels come with a nylon washer, to act as a spacer to help keep the wood from locking on the mandrel, and a black thread-protector cap.
The #2MT-A mandrel fits all lathes with a #2 Morse taper. The thickest diameter is 7/8” and is preferred by turners who do not want to use it in their jaw chuck and are more comfortable with the thinner diameter. The spanner hole is used for leverage to help loosen turning; use 1/4" allen wrench or screw driver (photo)
The #2MT-B mandrel fits all lathes with a #2 Morse taper. Because the body is thicker, 1 1/8” diameter, this mandrel has the additional option of being able to be used in a jaw chuck (see photo to right). A lot of turners do not want to remove the jaw chuck for each stopper. This mandrel has all the same features and costs the same as the #2MT-A and the spanner hole used same as above.
Draw bars hold the mandrels in securely and are 1/4-20 allthread (any hardware store) with a washer and handle to tighten it. You can also make your own as shown here
Mini and Midi lathes use a max. 10” length and full size lathes a max. 15” length.
The 152 mandrels are made to thread directly on the head stock spindle as shown on the right. Does not use a draw bar. In place of the spanner hole, there are flats on 2 sides of the neck to use pliers. There are 3 thread sizes:
1” x 8 tpi = all Jet, Rikon and most midi and mini lathes
1.25” x 8 tpi = Robust, Laguna, Nova, Vicmarc,
M33 x 30 = Oneway full size lathes
The 157 is made for the Shopsmith lathes. It has a flute in the threads to make it self-tapping and the spanner hole for leverage when removing stubborn wood. It has a 5/8” opening for the headstock spindle and comes with the allen wrench for the set screw which is set at the proper 3 degree angle.
