Jack-
I added a number of his articles today, because they are excellent reference sources, and he has no problem with copying them, as long as no changes are made (he refers to this as "protected by copyleft").
I have an AXA for my 10" South Bend and was told that is the proper size for that lathe. The BXA size seems to fit the industrial type as opposed to home shop lathes like a South Bend or Atlas.
Best,
Nelson
