I bought a 1948 Doall 16" it has the 1" blade on it. Awhile back I think I read I could use a 3/4" with this guide, but I'd have to confirm that. I do not have a confirmed list of what I will cut, but I would like SS to be on the list. I have not ordered anything so I'm open. It came with a Lennox classic he was using for copper, and brass, not sure of the TPI but it looks a little courser than 10/14.
