I am currently testing a 10ee to see if it's fate is the scrap heap or a nice home in my shop. My friend Andy purchased the machine in order to transfer the taper attachment to a newer 1990's 10ee and is giving me the older machine in a trade.
The machine is, as best I can determine, a 1951 MG 10ee square dial equipped with ELSR and an air powered collet closer. The serial number is stamped on the way and matches an aluminum plate that was installed where the standard Monarch Information plate, now removed, is supposed to attach. There are also some smaller plates attached in that general area but they are all painted over. Also has an ID tag from Sikorsky.
The machine has already won the " The Worst Paint Job " award and is now competing in the "Worst Worn Machine Brought Back To Life" category. .. Stay tuned to see the results.
I've spent the weekend removing transformers and wiring that were used to " clumsily " make the 220 volt coil work on 440. Then I used 5 cans of electrical parts degreaser to clean the years of caked on grease, oil and dirt off of the motors, generator, contactors and switch panels.
The drive motors now start up on 220 volts and sound pretty good with no sparking from them and just a little sparking from the forward and reverse contactors. The drive is not reaching much over 1000 RPMs so I have some more reading and checking to do... With it running I can at least evaluate the machine to determine it's fate...
On the head stock end the drive belts are a little loose and have worn deep grooves in both aluminum tensioning pulleys. When the machine is turning the belts are not even riding in the grooves so I'm not sure how they got that way. I need to buy or make new pulleys.
First question....
I have the main AC motor rotating in the correct direction according to the motor's rotation arrow. The controls for making the spindle rotate counterclockwise, when looking at the tail stock end of the spindle, seem to be backwards from the YouTube videos I have seen. This has the ELSR controls and there are two ways to engage the spindle. The first one is a lever attached to the lower control rod for the apron. When I raise the lever up towards the head stock it puts the spindle into reverse. Is this correct? lowering the lever to the middle stops the rotation and all the way down spins the spindle forward. I realize that turning the ELSR dial changes directions but the only way to make it rotate the way I think is right is to leave it in left thread...
Second questions also has to do with this lever. I find it is really sloppy when it is moved. There are no detents and finding the stop position is really difficult. In it's current condition this makes the lathe very dangerous to operate. I've opened up the end of the ELSR box and observed the micro switches in operation. To me it looks like there is no way these switches provide a detent for the lever and rod and there must be another mechanism that gives the lever more control... Also tried using the lever mounted to the apron for control and it is even worse. What should I look for to find either worn parts or adjustments for this lever?
