Nice work :wave:. It is also possible to take a shortcut, and use threading tap, as I have used to make my primitive rotary table.

No photos yet, as I have to find my camera (again).

:offtopic:. Anyway, calculating the circumference, that matches certain number of teeth, is chinese arithmetic to me. Resulting machined workpiece never match my calculations. I have read the theory that's behind it, and tried to adapt it in practise in several ways.

John Hill:
Thanks for the kind comments.

Sorveltaja, if I understand correctly the number of teeth will usually be 2 less than you would calculate using blank diameter and tap pitch.

NickG:
That looks to have worked superbly ... I always thought that was just one of those things that was 'impossible' and you had to buy them :lol:
