Re: Tinsmith's in frame gas tank for cantilever Schwinn.
Where did we leave off last?... ah yes, Dan was joining the first side to the long top piece. In the next to last photo of this post he is tacking the pieces together at intervals to hold it tight, else the spring of the metal wants it to have a gap. Once tacked together he then goes back to run a continual bead across that run. In the final picture he has wiped the tip of the soldering iron against the sponge and is now dragging it across the block of sal amoniac, recharging the iron with flux so that it will again accept the solder. On the longer runs you can see how Dan holds the solder so that it continually recharges the iron making it possible to run a continual bead on the tank. Pretty cool.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
