[QUOTE="tobnpr, post: 2359165, member: 68758"] What Shortgrass said. I have a Sheldon that is dedicated for chambering work. 11 x 36, known as the Mobile Machine Truck lathe. Used in the military (mine is circa 1950, engraved USAF), light use, no wear ridge, short headstock perfect for barrel work. The 11/12 Sheldons all had 1-3/8" spindle bores far as I know, most with 2-1/4-8 spindle noses- same specs as the SB Heavy 10's. Bronze bearings- if in good shape- are perfectly fine. Old ones have top oilers (which I'd be more concerned about due to age). More recent ones have front oilers, and the latest models had Timken roller bearings. Since it was apparently a hobbyist machine it's whole life I'd DEFINITELY give it a serious look. Not familiar with the KS990 model... There is also a Sheldon owners forum that has a lot of info (old-timer moderator was a manager at Sheldon and is a wealth of knowledge). Parts aren't as easy to come by as they are with SB's (mine can be seen behind the Sheldon), but they are remarkably similar in operation and construction. These old lathes can last **** near forever with light to moderate use and care, OIL.... Happy to help, PM me if you like. Here's mine: [IMG]https://i.imgur.com/qosbMGH.jpg[/IMG] [/QUOTE]
