Hi Chris, don'y kanow about no liquid solder, jest used plain old 40/60 I use fer me electronal projects. What's the liquid do? Never heard of it in Kobblers Knob.
Learnt two things about boilers doin' that. 1. it's the last one I'll ever do, unless something big changes and 2. respect t., and anyone else who does a scratch brass steamer. Actually, you make the cones and I'll solder 'em all day long. That cone was a Royal PITB! It's started life as flat sheet. Up til whenever I posted that durned thing last night. Sheesh.
