Recently I purchased a 12 inch bench top engine lathe for home use. This lathe was sold under the Craftsman name from the 30's until the 70's. it was built by the Atlas press company and for being small a very versatile machine. So I join a facebook group that supports these machines and asked a question about the spindle thread that the chuck mounts to asking if it was a 1-8 thread or a 1 1/2-8 thread. Got several good replies the HE popped in stating..... First it is a 1.500- 8 not a 1 1/2-8. Then went on with all his technical jargon which being a toolmaker for more than 40 years I fully under stood what he was saying. But those of us who have practical machining experience do not talk about threads and machining like this. I know, I know its facebook but good grief it just gets tiring.
