California's Wilder State Park has a Pelton powered line shaft woodshop that includes a metal/wood lathe of unknown pedigree. We believe it is circa 1890's. I volunteer there and need your help. How old is it, who is the manufacturer and how can I fix the tailstock? I retracted the screw spindle to eject the tapered live center, and it no longer will move in ether direction. Put another way, it turns but does not move the screw spindle.
