Hey guys (and gals), I know you have all seen the plaintive cries of WIAD owners already, but I could use a little help.
I knew this lathe had electrical issues, but I also knew it was priced pretty reasonably and came fitted with both the taper turning attachment and ELSR.
I figured it would be pretty easy to use my other broken 10EE (more on that in another thread soon) as a reference and at least make one good one.
Not so fast, the cable bundle coming into the drawer of my very regular lathe is 15 conductors, the new lathe is a full 23. To make matters much worse the owner had electronic issues a couple decades ago and was in the middle of tinkering with it when ... LOOK, a squirrel! So there were several wires disconnected to do some sort of test. The previous owner was apparently following a procedure titled "Instructions for disabling motor field"
Of which I have one page of looks to be a multi-page document.
I connected up the obvious stuff and there are signs of life: The time delay works, then start will turn on the tube filaments and lock the main power relay.
Selecting forward or reverse is less solid, one thyratron flickers in time to the forward or reverse relay going thunk...thunk...thunk, thunk every .5-2 seconds.
The acceleration relay isn't doing anything for what that's worth.
Wires still disconnected (that I know of):
C3 in the relay box makes it's way to the electronics drawer and then I'm not sure what it should be hooked to.
Similarly wire B8 comes to the drawer and I'm not sure where it should go.
One the back of the relay box, there is a short jumper-like wire hanging off post B6.
Oh, and what's this thing on the end of the ways?
I have some various schematics including some supposedly for my machine from Monarch, but no two seem exactly alike.
There is also a FAX from 2001 from Monarch listing solid state upgrade pricing and a printout discussing my machine
Apparently it was manufactured April 10, 1954
