$20 with a 5/16″ stub drill bit ($21.60 if purchased separately)
#2 Morse taper mandrel has a 3/8″ x 16 tpi threaded stud with the unique™tapping flute making it the most efficient mandrel on the market. It also works with other projects: ice cream scoops, shaving brushes, pizza cutters, etc. It has a black oxide coating to prevent rust. The 13/16″ diameter collar is the same size as stopper tops. A spanner hole makes it easy to get leverage when the wood gets difficult to remove (see photo): use a screw driver or allen wrench. The back end of the mandrel is threaded for a 1/4″ x 20 tpi draw bar. See Draw bars
Mandrels come with a thread-protector cap and a nylon washer to be used as a spacer to help keep some wood from locking on too tight when you are turning your project. *note: if the wood does get a death grip and you can’t get the project off the mandrel, put the whole thing in the freezer for 10 – 15 minutes and it will unthread once the metal shrinks.
