Trapezoidal threading tool jig from September 2018,

I filmed this some years ago and wasn't impressed so didn't publish it but someone asked about it so here it is.
Originally designed to work on my surface grinder but it will work equally well on a mill using a cup wheel in the quill and the jig in a vice and usual safety precautions.. The flat on the end of a threading tool can also be ground while in the jig and I have developed a measuring tool, similar the screwcutter one, for trapezoidal tools for the extra accuracy. Enjoy and comments always welcome.

Good to see you are still playing in the shop. Pretty good one handed action.
