Nice work doubleboost!

An 8 pitch is scary stuff on a small lathe.
When that tool is headed for the chuck at .125" per rev
it doesn't allow for much error in your reaction time.
Cutting an internal thread compounds the "PUCKER FACTOR".

:bow: on your efforts!

The best part of doing a job like this is the total focus you need all the everyday problems of work kids mortgages go away for the afternoon ,the satisfaction of doing something to make a very old tool work again is priceless
