[Elecraft] Need construction hints/advice

[Stuart Rohre]

Actually, in some 45 years of use, I have found Multicore Solders to be the
easiest and most consistent to use.  I have used SavBit alloy by Multicore
at work in a variety of gauges.   For K2 soldering, you do not want too
large a solder for best clean looking joints.   The gauge I used was  20
SWG, 0.036 in.

I use it on all my kits, and the K2 was done with it.   Never a problem with
flux needing cleaning, as there is little to no residue on any joint.  With
a soldering station with two heat ranges, I can tin crystal cans quickly, or
solder the smallest component.  Although I prefer the heat controlled Weller
station at work, at home, I could only afford the dual heat Ungar station,
but it has been adequate.  Even does PL 259 coax plugs!

The choice of a solder is the key along with clean right sized tip, and
adequate heat, with tip wiping in between joints, are all the keys to shiny
bright joints each time you solder.  Use a clean sponge and clean water on
your soldering station or iron, to wipe the tip against the wet sponge in
between several joints.  The 63/37 Multicore solder is one I like, but the
SavBit 60/40 is OK as well.
