[Elecraft] Random K2 building hints for those starting out

[Harry Yingst]

I only do one part at a time (a lot harder for me to screw up that way)

If your fingers are getting that hot then your cooking the component,

so it also serves as a heatsink/indicator that your dwelling too long
or need to turn up the heat on your iron.
