Hi Andy
The T-slotted cross-slide explains it.
I will see if it feasible to make some sort of adaptor plate to allow the mounting of the tool post on the existing cross-slide.
Thanks for info.
Mike

Dear All
I was looking at this old post about Rear Tool Posts and saw the drawings which will allow me to fabricate one.
Does anyone know how the Rear Tool Post fits onto the Lathe? A drawing, sketch, template or explanation would help.
Thanks
