Our entire hobbies are "p**sing around"…

Speak for yourself, don't presume to speak for me. My aim is to make good parts with the least expenditure of time.

For the thread size concerned, especially in brass, I just use a plug tap or screwcut. No need to use taper/second taps.

What I've tried to say very clumsily is that our hobbies are just that; pastimes being done for fun. In your case, highest quality with maximum efficiency. But it's still just a leisure activity.

I've been approaching the threading from a different perspective. Do I really need full depth threads for my fastening needs? Usually not, so instead of selecting the exact drill diameter I choose one of the drills just a few thousands of an inch bigger. Suddenly, starting a tap is so much easier and breakage of the tap has been eliminated.
