[Blindtlk] Soldering revisited

[David Andrews]

You might want to talk to Lloyd Rasmussen, 
lras at loc.gov  He is an electrical engineer, and 
has experience in this area, as do others.

There used to be a publication called the 
"braille technical file" from the 
Smith-Kettlewell Institute in San Francisco.  It 
all may be on-line now.  They had a series of 
articles on soldering -- back in the 70's I think.
