Hello,
for some reasons this centre screw is worn.
It would be very helpful if someone tells me the thread size.
Drags no 110730.
Not sure but it might be 8BA. Also don't know tpi.
I would prefer use a friends lathe than ask drags.
Many thanks - Ralf

It's 3BA.

hi Ralf i think it would be better to get one from Drags if they have got one , than messing around making one , it is a easy old size to get

You are right, Johnny.
Will do that - Ralf
