I think you have found the problem Don. It's the LEAD!
I just went out to shop & am looking at a roll of copper pipe solder from
Lowes. It is Oatey brand solder & says 95/tin, 5/ant. I assume that ant.
is antimony. This stuff takes more heating with a propane torch for flow
than regular solder. It also needs flux. So I think it would work fine for
radial joints, since the lead is missing.
I have not tried this since I made sure all my 14 short radials are
continuous copper wire, but it should be a solution.
DF2PY was pumping into central Fla last night, so we gotta get these
projects wrapped up soon & be ready for Top Band action !
