If you ever attempted to make an outside thread using a threading die, you know what a challenging task it can be. Starting the thread and keeping it coaxial can be very tricky. To help with alignment, I designed a tool that keeps the die holder perpendicular to the stock axis while threading. It makes starting the thread and keeping it aligned a breeze. STEP files provided so you can customise it to your die holder, especially the Custom* files.
