I have a 50's vintage Monarch 10 EE variable drive toolroom lathe with a factory tracer and turret, burried in the back of a friend's shop. I used it for a good number of years. It needed the ways scraped and trued, maybe just reground the bed would have been in order.
Chuck that is one sweet lathe worth fixing up. If you want I can give you the current address of the Monarch company. Believe it or not they will completely overhaul that lathe although I think shipping from CA would choke a horse. My 12CK is a tool room lathe too. I like it so well that when I die they can bury the Monarch and a set of Starrett mikes with me.
