Hi CAL

Yes, you are correct, this design is not balanced, but it is the reason that it will work. We need one unbalanced winding in order to generate the initial torque to get the MG going, then...

Hi CAL

I used the diagram presented by Flail in the Sticky thread above:

Hi CAL

One more thing that I should mention:

What if the "SUPCO APR5" fails to disconnect the START capacitor, or it intermittently closes the contact due to some unknown reason, would this be...

Hi CAL

Right now I don't have a clamp Amp-meter that I could trust. My previous B&K 350B that I bought on ebay gave me wrong readings, so I am basically ignoring its existence.

First, I want to...

Ok, I only wanted to know what is the general size of the two pole breakers used in the electrical panel when the 10ee is powered by a single phase 220V and with the MG modified as per the "sticky"...

I am asking about the breakers in the panel that supply power to the machine.
The lathe itself does not have any breakers. My breakers seems to pop off once in a while even if the lathe is just...

What is the correct two poles breaker size for a 1942 10ee with MG drive?

The MG was modified from 3 phase 220 Volts to a single phase 220Volts

No, so far it is not very good (it does not work at my end). I am still investigating why it does not run as described by the previous threads.

After purchasing a couple of AMP meters on e-bay,...

Well, here we go. This past weekend I finally decided to put power to the MG after checking all the connections a million times, everything was a go at the end. In this test, only the MG was powered...

I am in the process of converting my 10ee from three phase to single phase 220V input using the information provided on this forum thread. I am almost ready to power up, but this weekend I just...

Hi

I currently own a DV59 precision tool room lathe that I would like to trade with a Mill machine or also sell. I am asking $1500 CND dollars.

The lathe is 9" swing and approx. 24" between...

Thank you for the advice. I did manage to take the impeller off using the two bolts as you suggested, thank you. My two bolts holes however, are for a 5/16"-18 bolt.
Next, (this weekend) is to wash...

Hi

I am trying to make this three phase to single phase modification as you described in details above, but I am stuck in the removal of the fan impeller. You say that there are two alan-key bolts...

Can some one tell me what the extra hole is for?

Hello Bob

I would like the parts since my switch plate is cracked.

Let me know if they are still available

Cheers
Pier

Thank you rkepler

I had the same thoughts, if the dog was worn down this would generate more backlash than necessary, however I still want to get the front cover off the "backgear" to have a...

What about if you use a three phase inverter (i.e. Single phase 220Volts input, three phase 220V output). For a 5HP they sell for about $495.

I have a question:

I have a 1946 10ee all in working condition with the original MG and DC motor set up, but I don't have three phase in my garage. Can I just buy a VFD that can handle 5 HP and...

Over the weekend I was trying to open the backgear front cover to determine the reason for the large backlash, but I was not even able to remove the front pulley wheel to get access to the socket cap...

Not that I am planning to abuse the lathe by slamming from forward to reverse, I just want to compare my current pulley backlash with others in the same category and take some action if it is too...

Yes, this is the pulley wheel right on the Backgear of the motor. I am replacing the two V-belts and this is the reason that I have noticed the backlash. My concern is this:
What happens when you...

I am in the process of refurbishing a 1946 10ee, I have noticed that the backlash on the Backgear pulley is considerable (about +/- 3 to 4 degrees) this was measured with the Backgear engaged in...

Hi

I am trying to disassemble the apron on my monarch but I am having problems removing the two clutch sub-assemblies as show in the attached photo.

Hi Cal

Lead screw is finally out.

The pin did look very good and smooth when I took it out, that is why I assumed the tapered hole was also fine. However I took your suggestion and I run a...
