Did my eyes deceive me, or did Myford roll the threads on their leadscrews?

There are faint marks on the thread crests near the start and finish which suggest this.

It is quite possible. Leadscrews can be made to a high standard by rolling. They quite likley buy them in from companies that specialise in that sort of work.

Thanks John,

I was beginning to doubt my observations.

The 1/8″ pitch leadscrew came with the Norton-style gearbox, when I bought it c1965.

A great step forward for me.

Regards,

Sam

I made my own gearbox. Cutting the leadscrew down to length was one of the more irreversable parts of installing it.
