[GreenKeys] The most annoying part of Teletype restoration.

[John, W9DDD]

Lacing:

I also considered that.  I probably have a ball of it somewhere here. 
For now this was just a case of removing some modifications on an FAA 
cabinet.  They added two lamps to indicate various kinds of status. I 
just want to remove the wires from the lower part of the cabinet and 
leave the lamp wiring as is.  I had a couple of cables hanging from the 
dome that I just wanted to coil up and tie wrap out of the way.  The 
stiff tubing didn't allow coiling, even cracking in places.  I ended up 
cutting the tubing off so I could coil up the wires (4 or 5).

So far I haven't had the printer and keyboard cables so stiff they won't 
get where they belong, I think lacing might the the proper way to go. 
I've never seen lacing crack.
