Ainjest Rapid Threading Attachment Part 4

In this final part of the series I demonstrate cutting threads using the Ainjest. I demonstrate 2 imperial threads cut without a threading dial, then use a Metradial to cut 2 metric threads on my imperial lathe opening the half nuts and winding the carriage back with the carriage wheel. For a threading tool I use a reground scrap carbide insert and show the regrinding procedure.
