I think most lathes probably have a shear pin to protect the gears that drive the lead screw. Most likely brass. When I got my 1440 I went over it with a fine tooth comb and discovered a steel roll pin in the lead screw. Thinking that seemed like a bad idea I looked it up in the parts diagram. There it showed a brass shear pin. I made one and replaced the roll pin. I should have put punch marks on each side so if it does get sheared I'll know when it is lined up to be able to push it through. Will do tomorrow. This information is courtesy of
