New Project: Plans for a MT3 Die Holder (for 1″ and 1.5″ Dies)

Here’s a set of plans for a handy Die Holder that fits any lathe with a #3 Morse Taper tailstock.

The aluminum body of the die holder holds the die perpendicular to the axis of the spindle rotation and rotates freely around a steel shaft firmly inserted into the tailstock. This ensures that your part is threaded perfectly.

Here’s a picture of the Die Holder with a 1.5″ die inserted:

Here’s a picture of the Die Holder flipped 180 degrees with a 1″ die inserted:

I got the idea from Steve Bedair’s Die Holder and I adapted it to look similar to a smaller die holder sold here by

I created the plans myself using Autodesk Inventor. It was my first attempt using the software, and my first time drawing up plans for the machine trade – so if there are any errors please let me know and I’ll do my best to fix them.

Here are the plans (in PDF format):
