I recently picked up a 17" Leblond lathe of mid 50's vintage. From what I can tell so far its an OK machine. I am wanting to measure the wear on the ways and from searching around it sounds like a somewhat difficult task without good instrumentation. I am hoping to do a little better than a straightedge and using the optical comparator I was born with. So my question is if I chucked a ground drive shaft (45mm) and held it with the tail stock, would running an indicator across it tell me anything useful?
This seems like quite the nice group on here.
