Something came to mind for butt soldering the smaller pipe (yes pipe) to the massive pipe. It didn't work as well as I hoped, but this is 1st try. a good 'nuff for now. I used a drywall joint compuond (mud) to create a damm for the solder. The hope was that it would also hold some heat from the small plumbers torch I was using. mHi, yall. I've been trying to plumb some parts and have used every trick I know. I've brazed SS to copper, tig'd the massive copper, soldered the smaller copper, bent tight coils with sand, and engineered a needle valve all for low pressure application.
Something came to mind for butt soldering the smaller pipe (yes pipe) to the massive pipe. It didn't work as well as I hoped, but this is 1st try. a good 'nuff for now. I used drywall joint compound (mud) as a dam to contain my sloppy soldering and hopefully insulate the massive pieces to hold the heat. My propane rosebud is out of propane. This is what it looked like after ALOT of time. I used 12ga copper and vice grips as a soldering iron to try to direct the flow. I can't do it any other way. It scrqtches the coper to allow adhesion that flux just won't do. After about 20min with a dremel, file, and various polising techniqes...this is what I got. The best secret for polishing copper/aluminum is a good 'ol SOS pad. Now on to my next hobby!
