Re: I don't think threading is so very difficult..

“ As I recall, it is easy enough to thread the male side by hand and then use a couple of pins offset by the length of pitch to rig up a jig with a cutter for threading a bore to match.‘

John,

You’re right again. I ordered a new copy of The Workbench Book, the old one being lost in my jumble. New one arrived today.

A Greek engineer under the name Hero provided a description and maybe drawing of such a machine in the 2nd century BC! Hero’s jig used 6 hardwood pins located 60 degrees apart radially (and with the required spacing) to register the tap.

The author Landis has a lot of material on tapping female threads into wood, particularly the ancient methods, or ones the Dominy’s might have used.
