Managed some workshop time, yesterday.
While I was busy, I set the lathe running in Lo gear, 700 rpm.
Tweaked the bearings, after 10mins, and upped the revs.
Eventually reaching peak revs in Lo, 2,180. (Seems rather high to me)......

All seemed ok, so I changed to Hi gear.
Ran for a while, eventually reaching 3,000rpm. The supposed peak revs.
Wound it up, a bit. Reached 3,600. The digital reading stayed there, but the revs continued to obey the speed control.
The bearings seemed happy. Not getting warm at all. So, I tweaked the speed control a bit more...
The revs climbed higher! Until the motor cut out, with a,
"PUP". ![:zap:](https://madmodder.net/Smileys/default/electricf.gif)
Apparently, no harm done! (Except to my nerves). It re-started, as usual.

Grabbing my laser tacho, I decided to see just what
were the peak revs?
It peaked at 5,000rpm!! ![:bugeye:](https://madmodder.net/Smileys/default/confused0068.gif)
.. Before going,
"PUP",

again.
That's just a bit too enthusiastic, for my liking.......

Time to check the motor. Should give 6,000rpm. According to the label.....

Reflector tape, on the pulley......

By ek! We must have the GT model.......

John suggested checking the voltage supplied to the motor. As, this determines the motor speed.
The result wasn't helped by my 35yr old meter reading x 2(+).
500+ volts! I don't think so.......

New meter on order. Further fumblings, in a few days time.
Any comments/ helpful advice gratefully accepted......
