Monarch 10EE Tool room lathe

[gimpyrobb]

Monarch 10EE lathe. No tooling, but has been rebuilt buy the military in 1987, originally a 1942 model. It seems it might have been updated to a newer DC motor drive. It also has an X & Y dro. Looks like 440v input. Located in Columbus Ohio.
$3000 or best offer(within reason).

i was going to buy it, until you mentioned rebuilt mid 80's. military personal was kinda trying to clean up there drug use at that time

I wouldn't be surprised if Monarch did the rebuild on it. They do indeed remanufacture their own machinery. I would call them with the machine serial number and investigate it for myself before writing it off. If they did the reman, you can assure it was done right, and that is a great buy on that machine if so.

Worth a look see anyways. They're great lathes.

IMHO of course

Too bad it's not closer to Washington, I'd like to take a look at it! It looks a little rough even on pic tho,

It might not have pretty paint on it, but if it was rebuilt by Monarch in the late 80s, it's prolly a pretty tight machine.

They were in the $60K plus price range new in the '80's.....

The Army and Navy both had shops that rebuilt machines in the past. There is usually a tag on the machine with the date of overhaul if done by the military. If Monarch did the work the serial number on the bed would have an R suffix. This is a Round Dial machine built during war production, the notable distinction being less concern with cosmetics and the use of tin for the placards instead of brass. This should have had a motor/generator drive originally, what it has now? The replacement drive could be a three phase OR single phase system. My 1976 10EE has a replacement drive that is single phase, several of the DC drive conversions were three phase however.

Steve, if I got pics inside would it be apparent what drive it has?

It was rebuilt by the military, heres a pic of the tag.

It's surely a POS now

I bet it's quite nice. Would like to see the ways and movements. I bet they look good.

That's a reasonable price. I'll own one when I got the room and some extra dough.

Take some pics in the drive cabinet, I will give it a try. My guess is it will have two motor control boxes at lest. There should be a larger box to power the armature, a smaller one for the field and perhaps another box or board with a field loss relay. How many wires actually go to the drive boxes 2 or 3 will tell if it is single or three phase. Also; IF it is designed to operate on 240 volt single phase service there should be a rather large transformer to increase the AC voltage going to armature drive. To get 240 VDC from single phase service you need about 270 VAC.

There are a few guys on the Monarch forum at Practical Machinist that really know their stuff on DC drives. I will do what I can or I can cross post it as needed.

Thank you. I will open up the bottom and get more pics next time I'm up.
