Well, I am now the owner of this Monarch. It actually didn't look that bad from the pictures, so I drove up to take a look at it in person and it looks even better in person. It's in really good shape for it's age. They even let me look inside the headstock, at the gearing, pretty johnoder's recommendation, and it looked pristine except for a slight wear pattern on a mid range gear. Anyways, it is replacing my SB 16, which was, for lack of better terminology, a tide me over lathe, that I often had to go slower and lighter than I expected. This should put me back to where I grew up, running a lathe that just doesn't care how much you want to take off in a shot. Long story short, I still have to get it moved and setup in my shop. I do have some questions though.

So, I guess my first question is in the following is, what do the build numbers mean?

own the exact same machine, in fact my serial number is only a hundred or so away from yours. I have re-timkenized my headstock, working on the apron and crossfeed now, really just doing a complete rebuild for giggles.

this is an awesome lathe, ways are near indestructibly, unless truly abused. Check the clutch thoroughly, adjust properly and you should be good if condition is as you say. You can contact Monarch for the original build sheet. Mine was built for Bendix and was moved to Clark, and finally Dana as a tool room lathe according to available information.

Let me know if you need anything. I have finished a complete rebuild of the head stock since Dana employees ran without gear oil for some time. Spindle bearing in mine was a Class 3 (0.0003" runout) and replaced with a new bearing from Emerson. All other Timken bearings are available. My ways are in great condition though I have yet to quantify on actual part.

Make sure oil pump is working and each feed line is clear. You can manually activate pump, disengage oil lines and confirm flow to clutch actuator, and both spindle bearings.

good Luck.
 
You have an odd compound compared to my August 1946

"Manual" available for emailing if you want to private message me that address

The usual very slim Monarch offering

Good catch, I didn't notice that. I'm not gonna say it, mainly because I'm never that lucky, but that compound looks like the power-angular feed one.

This is why I'm thinking it might have it, although I don't know how to engage it or if there was a version of it that just used one like this. It does definitely look like that compound rest though.

I'd guess the little gear box on right side with lever in your example photo is related. You have to have some way to make a power compound "go"
 
See, I thought that too, but every example I've found had the dual compound rests on the older machines and on the newer ones, there is a knob on the apron you pull to engage it. I wonder if there is a way to engage it by pulling the cross-slide screw in or out.

Anyways, I plan on moving the lathe on Thursday.

Unbolt the two lock nuts for setting the compound angle and lift it off and look to see if there are drive gears.
My guess would be the original compound on your lathe was worn or damaged and this it the back compound off of another larger machine that was leaving the shop. Back compound probably did not see as much use.
 
Went and got the new girl today. Well, I thought I had everything locked down and ready to travel. Turns out, the clutch covert blew off somewhere in-between Mass and CT. I really hope it didn't hurt anyone. Anybody ever make one of these from scratch?

Agree about the depth may not be deep enough.

Also I wanted to point out this is a great example of why moving any machines they should be shrink wrapped and tarped. The shrink wrap will keep loose pieces from leaving and the tarp will keep the shrink wrap from shredding in the wind.
 
Now, I started digging into it. The motor is missing the terminal cover and I haven't been able to find the label plate to see what it is wired for. The heater box, I am not experienced with those, so that is gonna take me a minute. And the upper contactor box is missing it's paper work and some safety closure pieces, easily fabricated. The thing that gets me is the amount of chips inside the boxes.

This thing also came with a transformer on a stand, but I would rather not use that thing judging alone judging by the crusty wiring. The transformer is a 230 to 440. I haven't totally ruled it out, but I'd like to run it on the lower 220V if it is at all feasible.

That little transformer is to run the relay I think that your motor is 440V and is signal voltage only.
 
You will need to see how the control transformer is wired If it is wired so that 220V is the output is going to the controls then your machine is 440V and you will need the transformer to power the motor 220V to 440V as your motor is single voltage only or you will need to change the motor. the coil on the relay is marked 220 the other way to check is to see what size heaters are installed in the starter and see if that matches with the HP of the motor.

Here is the plug from the wall.

Here is the inside of the control box and the heater up close. Anyone have a best guess on the size of the motor based on this?
