A friend of mine still feel happy with a Myford Super Seven we bougth together
in 1964.The belt has been changed to Powertwist and motor is 3phase VFD.
I made him a 3 mm round carbide tangential tool some times ago.

He uses it for most turning to day but I was never really happy with the Carbide fixing screw.It was a modified UNF 3/8 24 TPI.
Metric fine thread screws are not easy to find and I want to try a differential screw that is made from a M8 countersunk with a UNF 3/8 head thread.
This gives a resulting movement of 0.2 mm per turn.
I have also invested in a swing grinder with a diamond disc and can modify 2 times 2 mm square carbide to very precise limits.
A start has been made on a pair of Myford specific holders for 3 mm round and 2 times 2 almost square carbide.
It is my hope that the Myford Church will test the holders compared to the most expensive QCTP systems,but in the meantime I will post pictures as I go along.First picture shows about 2 hours work.
Material is 20 times 30 mm hot rolled steel.
