[TR] soldering

[Bud Rolofson]

I haven't seen sanding/buffing the surface mentioned either.

Putting a "shine" on the metal you want to solder has always worked  
better for me than not.  Solder likes shiny metal and flux.  Works  
similar to welding...if you don't grind it you're not going to get a  
good weld.  Try a tiny round file in the bullet connectors to rough  
the surface or anything to get the surface layer broken.  Scratch it  
with a pin?
