Hello Twistdrill,

If you want to take the easy way, the half nuts are probably still available
from Hercus, at a price.

Another source is Mick Moyle's Engineering Supplies at 40 Edward St Summer
Hill 2130, phone (02) 9799 8444. You can email them: .
Last time I was there they had a set of half nuts in stock.

I have no connection with the company except as an occasional customer.

To Email, replace 'xxx' with tango papa golf.

hello everyone
the half nuts on my 9"hercus lathe are worn out.
I about to try and repair them. They look like a 3/4 acme thread.
Would that be right?
A hercus is a direct copy of a 9" southbend lathe, did they use an amce
or square
thread on their leadscrew?
Any information would be greatly appriciated
kind Regards
Twistdrill
