Dennis - I've found that If I left the tube ends lightly rolled (just like the tube cutter leaves them) the lead stays in fine. I'd recommend against doing anything while the lead is still hot - molten lead is scary stuff. If the lead falls out just use a larger tube, pull the lead out, and keep the tube for the next set of weights. For that really "high performance" ballast try a piece of CMW2000 from CMW Inc., of Indiannapolis, IN. 95W,3.5Ni,1.5Fe;.650lb/cubic in. It's much more compact than lead, and it won't get dented by much in the event of a hard landing (including armored vehicles);-) have fun - Rob Glover << Greetings, I'm making ballast in brass tubes that are 1" dia and 1" long. I poured last night and the lead shrank in diameter enough that it easily fell out of the tubes. This might not be too much of a problem for a smaller diameter tube. Should I: Heat the brass tubes as I pour, Press the lead down before it cools and just after I pour, Epoxy the lead in after it cools, Press the cooled lead causing it to expand and match the tube[I can make a fixture to hold the tube to diameter], Roll the ends of the tubes to prevent the cooled lead from escaping[easy for me to do also]? I think any of those would work, what have you found that works for you? ===== Dennis Phelan>> RCSE-List facilities provided by Model Airplane News.
