I'm really not sure. I suppose it could be a 3mm pitch? I'm really a total noob when it comes to threads and machining metals.

I can't find a lot of info on this lathe. It's a model 1910 A.V. Caroll. The lathe is massive. I might just have to model up the adapter and post it in the RFQ section.

Edit: All the nuts and bolts on the lathe are standard english measurements.
