    1940 Monarch 10ee rehab questions

    Thank you. That confirms what I was able to determine from the wires. It was the presence of the two right positions that do nothing that was confusing me as I could not think of any purpose for them. On the other questions, do you know if there is supposed to be a rubber mount between the...

    1940 Monarch 10ee rehab questions

    VFD is just there for 3 phase conversion. I do not have the coolant pump on mine. When I received my lathe, there is the 5 position switch on the front, which connects to the contactor at the back of the headstock. The switch activates the contactor, the contactor switches the power to the 3...

    I have a couple of Sundstrand drive specific questions that hopefully someone here can help with. I never got to see my lathe operating under power so I do not know how the original switch/contactor worked. I will be installing a VFD and want to use the original switch as the control but I...

    Thank you Grant. I already ordered a replacement 6204 based off of your thread. Your rebuild thread has been invaluable to me. I am constantly going through your thread as a reference on disassembly or assembly or to find info such as which bearing numbers. The documentation you are doing is as...

    1940 Monarch 10ee rehab questions

    Well just to provide an update on where I am at. As I started this thread as a rehab and not a restoration my goal is to avoid a big project. I don't want to tear it all apart and repaint it etc. I just want to clean it up, inspect and replace anything that needs to be replaced and use it for a...

    1940 Monarch 10ee rehab questions

    Thank you so much for posting the manual! I will start reading through it shortly. What makes you think it is the original collet rack? Compared to the one on your machine it just doesn’t look like the same build quality to me. I am interested what you see that makes you think it could be...

    1940 Monarch 10ee rehab questions

    I already had suspicions this one was home made and not original. The construction just doesn’t look up to the same standard as the rest of the mill, welds are not great, and the wood top surface damage seems more like it was chipped out from poor drilling vs just long term use. Strange. That...

    Requesting copies of 10EE lathe build data sheets

    Here is mine. Sundstrand drive machine. Because they accidentally sent me the wrong serial build sheet first I have another build sheet: Interesting that this second build sheet is a month earlier but 200 serials later. It also appears to be a motor generator version with 4K spindle speed...

    1940 Monarch 10ee rehab questions

    Thanks everyone for the replies so far. Yes I had found the round dial manual on Vintage Machinery, That is the closest I have found so far. I contacted Monarch and they confirmed that the manual they provide is the generic round dial manual and not for the Sundstrand drive. I will look into...

    1940 Monarch 10ee rehab questions

    I recently acquired my first lathe, a 1940 Sundstrand drive Monarch 10ee. I am in the process of cleaning and inspecting it and have several questions I am hoping to find answers to. First a picture of the lathe shortly after I received it. Just cleaned the bulk of the chips/oil off of it and...
