I just bought a new (to me) lathe for my shop. It's an Enco 14 x 40 lathe which is about 15 years old, and had been sitting for the past year or so (owner passed away, purchased it from the daughter).
Seems to be working fairly well for the most part with one exception. When I try to run the lathe at 1800 RPM, it starts up slowly, runs for a few ( maybe 10) seconds, then trips the thermal overload relay. At the next lower speed (1170 RPM), the lathe will start slowly but eventually get up to speed in 5 seconds or so.
To my (possibly naive) view, it seems that the motor is "working hard" in both instances, which doesn't seem to be a good thing. To this end, if I remove the chuck, the lathe will get up to 1800 RPM and seem to run OK (not the most useful configuration though).
Any advice on what might be going on here?
Thanks much.
