was it wired and fused for higher voltage, and then rewired for lower

Well, I doubt it, but I'll try to sort out the wiring and verify that it
was set up for the 480 we're feeding it, sadly there's only one torn
corner left from the schematic that was pasted to the inside of the
control box. It ran pretty happily for 3 weeks or so, irregular use,
not constant. I ran it for an hour or so last week with no troubles,
but I was running on the low end of low speed.

We recently purchased a used Clausing 2277 for the shop, today half an
hour to quitting time, it blew a couple fuses in the control box... Upon
inspection, it looks like the bottom of the variable speed pulley is
rubbing the top of the spindle pulley.

Is this a case where the operator just cranked it up to 'fast plus' and
opened these pulleys too far, or is there supposed to be some sort of shim
or stop in there to keep these from touching? I can try to walk it to a
slower speed in the AM, without the motor running that will be fun...
Upon inspection, the top cover looks a little 'home made' this thing may
have been sold off for a reason...

Clausing doesn't seem to have downloadable manuals, we'll try to get one
in the AM, but any informed ideas would be very welcome.

Hope the fuses are reasonably cheap.

I find it hard to believe that just running the variable speed to the limit
would cause a problem.

I doubt that the two pulleys are supposed to rub on each other... the
top flange of the spindle pulley is now very shiny and the whole thing
was HOT. The two pulleys are counter-rotating, so the friction would
load the motor pretty hard wouldn't it? What I really could use is a
decent exploded view of the parts relating to the variable speed
mechanism and the spindle pulley. I imagine there's a stop or bumper or
something that has either broken, slipped out of place, or disappeared.

I would check the motor over, and make sure the fuses
are the right size.

Thank you all, I do appreciate the help.
