[GreenKeys] Model 15 Restoration...

Fri Dec 6 16:27:13 EST 2013

You bring up a  good  point about the interface someone   could  do a good 
little cottage business making  some  of   these  for  sale.   Even for 
those of us     that  are  'into it'   many of  us  do not   have  time  for 
more construction projects.  I have  30  projects  ahead of the interface  but  
yet  need   one!

Keep up the  good   work on your 15!   for  fuses  yard sales in old  parts 
of  town  might   yield  some   cheap... or   savaging    derelict 
buildings...   might  also  check old hardware  stores that have been around a long 
time.... I have not seen  any new ones  in  home depot but have not 
looked....

OK  look at this....

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  :).
