Making a Custom Tap on the Proxxon PD 250/e Lathe

Making a tap is well within the reach of a home machinist, and I needed a very unusual tap to try and repair my G Boley watchmakers lathe. After watching a few other YouTubers' videos on the subject, I jumped in and made a tool which successfully cuts a thread. The thread in question is a left hand 4mm by 0.6mm pitch with a 55 degree angle. It predates most modern thread standards, and is not compatible with any older standards I can find. This video contains my first attempts at a number of skills, including precise thread measurement, heat treating steel, and grinding.
