[R-390] Now *this* is a really nifty idea...

Yes, you need the right solder! And the right heat, and flux, and a
clean mechanical joint that will not move while it cools.
 
Look up "eutectic solder" to find out why the right alloy makes a
difference.
 
A eutectic alloy of tin and lead is 63/37%, but most radio solder is/was
60/40.
 
Soldering copper pipe (before the plastic pipe industry helped to
declare insignificant amounts of lead as poisonous) helps to broaden
soldering skills.

Even with the best of instruction and many decades of daily practice,
without good solder ANYONE will have a tough time doing a good joint.

To wit; be sure to get solder designed for hand soldering work. Eustatic
stuff comes to mind, and these formulas ARE avialable in stuff that does
not use rosin in the core. BUT **you** have to be the one that uses the
right stuff.
