Tap refurbishment-anyone know someone with a lathe?

[oilboffin]

I think that somewhere I have/had a tap to that kind of square cut coarse cut thread.

But unless you find someone with the time and interest to make one on his lathe you will have a problem I think.
I have a lathe and you are right machining costs are about £55-00 per hour that's cheap too
I used to know an old retired doctor who would spend days/weeks making things up himself. I was honored as I was invited to visit his workshop and have tea with him. He will have died years ago and there are virtually no people like him left.

A possibly suggestion could be to plate it or hot dip "galvanise" it with lead. That could put a few thou extra thickness on it.

Brass is also ideal for electroplating. But to do that to a great thickness would need the special mix of chemicals in the plating bath as most plating is very thin for appearance only.

If only you had a tap then you could fill the female thread with lead and retap it.

Fookin Lead threads !!! You really do talk B* ll ocks !!

.....and to think we wasted time wiping those rolled/underhand/taft/knuckle/branch lead joints when all we had to do was cut a thread...
It pains me it really does...
