A manual is included. If it has a schematic I would be happy to copy and send to you.

Missed this! You bet I'd be interested in the schematic. Might be a cool trip down memory lane. Besides, one just never knows... :)

I started my engineering career designing analog motor controls. Digital isn't just 'close enough'. Modern digital systems can equal or exceed the capabilities of any analog system while still being less expensive and more reliable.

Easy there big guy, wasn't trying to ruffle any feathers. And I agree (see my comments about a BLDC...), so I'll just mark this down to a poor choice of words on my part. When I said "scenarios" I believe I was thinking my my old Carver and Macintosh amps. In stereos I could care less how good the specs are on a digital amp, I still prefer the 'warm' sound of a high-end analog tube-type class A amplifier. :)
 
If you want a schematic, call Monarch give them serial # of machine and they will send you one for a fee. The folks at Monarch are pleasant and accommodating. Some of their prices are modest some are very high. They can also tell you over phone how that machine was shipped originally. If I were looking to buy a specific machine that had been around the block a bit I would certainly call Monarch first for a little history. I don't know if Scott is still there, but he was a wealth of info for me when I bought mine years ago.

If the price of schematic is way high, you might ask over at PM if any of the chaps have one, that is where I got my generic one that covered early Wiad machines.

"Question? Why do you need a 10 hp motor on basically a 10x20 precision lathe? Just curious. "

VFD are constant torque below 100% speed. So, at 5% speed, 60 RPM, you got 1/2 hp. remember hp is speed times torque. Need that much to thread, most common use of very low rpm.

Also, yes $200 for a 10hp motor is a good deal. of course, somebody will come along and say they got one for $10.

I'd buy just for the insurance.

The lathe arrived yesterday all in one piece with only a small scratch on the tailstock. The machine is a thing of beauty. Bill did a great refurb job. It is now sitting in my shop ready to be hooked up. All that is required is a dryer plug and then into the 220vac single phase.

I have all the schematics and there are a lot of them. They are actual blueprints, old and fragile. I have no way of copying them and I'm sure Staples would charge a bunch and I don't know about quality of the finished product.

If anyone wants to borrow them to make copies let me know.
 
Glad it got there in one piece. Enjoy your new toy...err...lathe. :)
 
Got it plugged in, threw the switch, the blower came on, also a loud vibrating electrical sound, definitely not mechanical. After a short interval the amber light went on, the sound did not abate.

The motor was not running as none of the controls worked.

I called Bill but he is in Deer camp out of cell range.

Any input?
 
Hmmmm....That's not good

Was the machine wired for 230V single phase? I assume that's what you have. A loose wire on a relay or switch maybe?
 
Yes, it came wired for 22o single phase.
 
As crazy as this is going to sound, check the stop button and make sure the contacts are making good contact. Then maybe start looking for any other possible loose connections.

EDIT:

Maybe also check your input voltage with the machine powered up, it almost sounds like a contactor bouncing.
