Sill replacement with Oxy-Acet, techniques?

[Trevor Boicey <tboicey@brit.ca>]

I have to do a sill replacement, probably outer only. Due
to the what-I-know-and-own excuse, I expect to be doing
it with oxy-acetylene. Lyndsey Porter's book shows it done
this way, so I am confident.

  What sort of wire and techniques should I use for
the job? I am a careful welder but not well versed on
as many situations as I'd like to be.
