[GreenKeys] Lorenz Model 15 progress

[Ed Sharpe Archivist for SMECC via GreenKeys]

Yes!  this is  the  one  blessing we have  with  the heat here in Arizona. 
Things  dry  fast!
Oiling as  soon as  dry is a good thing  to prevent   rust.  Ed#

I have cleaned a few gunky units, though some folks may disagree with my  
method:
  - sprayed on some degreaser and let it soak a bit


- went down to the car wash and used the high-pressure wash hose  to clean 
everything off
  - back to the garage for a liberal use of the air compressor to  dry it 
off
  - let it sit in the hot arizona sun for final drying


However, be careful -- don't bend fragile parts with compressed air, be  
sure to dry and re-oil wicks right away...  Then you can take your time  
disassembling as much as is needed for the rebuild.

I've had the best luck with mineral  spirits.  I've tried citrus-based 
degreasers, Simple Green, denatured  alcohol, and none of those worked as well 
as mineral spirits.  Of  course, if Perc (TCE) was still available, that 
would be my first choice,  but it's not good for you or the environment...  


I'd love to hear from other list members  what's worked for them.

Greetings Listees,
Progress has started with the two Lorenz '15's I have. Thanks to  several 
great list members, I have several books and  tutorials on the  theory. The 
first unit tackled was the parts machine  keyboard, which I  have cleaned and 
believe I have working,  or at least close enough to  just need adjustment. 
 The typing unit is going to be much more of a challenge. It has a  petty 
good layer of gunk over it. Is there some bath you can put these in  that 
will cut the grease but not do damage? That would save a lot of time.  It's not 
imperative I get this unit running, it was destined as spare  parts for the 
good machine but its a great way to gain  some  practical experience with 
them.
 
Regards All,
Keith ve3ts
