I recently purchased an adcock-shipley bridgport that I plan to keep as it's nmtb30 spindle and I have a full set of tools for it. I also purchased a second BP for parts or to fix and sell. One thing missing on the Adcock is quill feed. Does anyone know if the parts are interchangeable? Is it worth the hassle? I can only see needing quill feed for boring. I was thinking this could be done with feed on the knee.
