I've just purchased my first lathe. It's a Boley with a D-bed and loads of accessories. It's one of the accessories I have a question about.
The previous owner had completely unwound the lower slide from its internal anchor nut. It's the nut for the adjuster for the lower bed.
It was easy enough to take it apart and reassemble it, but the thread in the nut needs to be re-tapped because the adjuster spindle is too tight.
Does anyone know the tap size for the thread?
It's a left hand wound thread and 4mm diameter.
Thanks everyone.
