Doing great. Tip for a torch. Get one of those screw on heads for small disposable propane bottles not those ones that are 12 inches high but just a slight bit bigger than a butane can. I get mine at Ace hardware near me. They are small but have larger flame and more heat than the small hand held torches.
Check out powdered Garnet sand. You can mix it with a little water to make it form like you want. It also can be pounded back into a powder and reused.
The clay in that video looks intriging. To me it has to have some sort of silicon in it to keep it flexible but heat resistant.
Reason that clay works and would be marvelous is it eliminates the need to keep the inner wires being under tension. Nothing worse than havind a piece with 5 to 10 wires all under tension, spring apart in your face, especially if your on carpet. That clay keeps the wires half imbedded. This leaves only a bit exposed to have the solder flow on. That again would be good for the tension reason, and the ability to do it on a domed piece. BUT…
You’re dealing with me and being thrifty/cheap. I do my pieces flat, then dome them after. I also put the piece very carefully on some elevated mess over an old cake pan. I flux with watered down paste flux. Then I take a piece of copper I hammered into a specialized spoon to sprinkle the powdered solder on. After I transfer the piece to a charcoal block to solder. This way I can collect the excess solder and reuse it. Otherwise you lose a lot of solder, even using that clay from the video.
I’ve lots of little tricks that I do, that I only think of as it comes up. I’ve been doing filligree for over 12 years. Its fun and frustrating. Any help I can give, just ask. It might jog the old brain to remember what I just do without thinking. By the way I work very hot, and have great results its all in the torch and wrist as you probably know.
AGGIE. In Orlando having its last cold snap of the year. Others are bundled up with 69 degree weather.
