Just received my copy of the magazine here in Canada and noticed the article on page 52 by Neil Wyatt about building a QCTP. Towards the end he muses about making a Tangential tool holder.

A few years ago I received a challenge from a fellow Model Club member, "bet you can't make a tangential tool holder". Well, he shouldn't have said that!

The photos in my album "Tangential Tool holder" show the holder I made to fit an A2Z QCTP. The tool bit is 3/16".

Photo A is of the holder and B shows a bottom view. Photo C shows it mounted on my now departed 920 lathe and photo D shows it alongside a Diamond tool holder mounted on an AXA size toolholder.

If you look closely at the shot taken of the bottom of the tool holder, you can see that I cheated by soft soldering a square hole tube in place at the correct angle. I then machined away the sides and ends.

Works very well but I did have the benefit of being able to copy it. Working out all the compound angles was fun.
