I have a 7x12 mini-lathe, import...the kind you can buy through several vendors but made at one factory. Cummins (ToolsNow) 5278.
A few days ago I noticed the spindle speed would suddenly vary. Usually up and down while I changed the pot, but even when I left the pot alone.
My initial thought was a dirty pot.
Today I was turning .005 at a decent speed and the motor stalled. That doesn't seem like much of a cut to do that. (I don't recall actual speed...but it wasn't so slow that I would think it was that.)
Any thoughts? Just a dirty pot? Or is the control board going?
As a side note, it's been pretty dry here and I build up a nice static charge when I go to the machines. (I have lino tiles on the basement floor). I've been getting zapped quite a bit. In fact, today, the lathe was on, direction was set forward, and pot was set to 0 speed...i.e. off. I zapped it, the motor suddenly started and then stalled.
Fooey...still have the flywheel to do. Maybe I'll just make an insert and use the flywheel off the Launch Engine.
