[GreenKeys] Model 15 Restoration...

Hey guys,
Just thought I'd share my latest progress...
And I need to give another big thanks to everyone that's helped me out so far, I REALLY appreciate it.  This thing would probably end up being a very large door stop without the help!
So, I haven't gotten much done since that arctic cold front hit us...can't really paint when it's ten below outside lol.  Did get a few other things done though...

Here's the motor base after being cleaned up.  Since I took that picture I also buzzed it with a wire wheel and unscrewed the terminal blocks...I'm still chicken to just cut the old speaker wire out of it until I have a better handle on how to wire it back up.  I might hit it with a light sanding disk to clean it up a little more, but after the wiring is out it's pretty much ready for paint.

Oh, and I cleaned the fuse block in the ultrasonic machine...it looks pretty nice now.  Can you still get those fuses?  Haven't seen one in a long time...would like to keep it original, but if that's not possible I'll try find something that looks like it belongs there anyway.

And here's the motor mounting plate before picture:

Pretty severely rusted and pitted.  Here it is after electrolysis:

And here after a little touch up with the wire wheel:

It cleaned up pretty nice...in the bottoms of the worst of the pitting, there's still some crud, but other than that it's great.  Just need to pick up another can of wrinkle paint and get some warmer weather...

Did get the motor cleaned up and painted.  Here's a couple before pics:

And here it is masked off and ready for paint...

I suspended it from the screw hole in the rear of the shaft with a metal coat hanger...worked pretty well, although spraying the underside (front) was kind of a trick.  Looks really nice.  After I sprayed it, I hung it up in the laundry room and let it dry for a few days.  I'll probably put it together tonight.  I might try and shine up that brass plate...was thinking about taking some 2000 grit sandpaper, and putting it on a piece of glass and carefully sliding it across that (wet).  Any kind of buffer would take the paint out, but this shouldn't.  Might be able to get a final polish on it with a dremmel buffer and some patience.  

And looking forward to trying to run the machine, I've got this I might try...

I think it's from the '50s?  Got it off ebay a few years ago for next to nothing thinking I might have a use for it someday.  I hooked up the audio input to my laptop and played a faux RTTY signal into it generated by MMTTY...the little cyclops display tube in the front seemed to respond to it, so I think it works.  What I'm going to do (at least to test the machine) is try and feed it that signal from the computer through this TU and least be able to give it some copy to print.  I got that to work with a Tono Theta 5000...it picked up the copy from my laptop just fine, so (at least in theory) this should work.  Eventually I want to run an RS232 connection to the 15, but since I lack the engineering skill to build an adapter I'll have to buy something.  Hopefully this will at least get me started anyway...  

Here's the connections on the back of it:

Sorry for the noob question, but are the 3/4 terminals a loop supply?  

Anyway, that's where I'm at right now...  It's getting there :).
