Belt Buckle Handcuff Keys: NEW UPDATE!

Your strongest low temp metal would be ZINC --- you can find it in used carboraters , car door handels and such.

"Aar> Hey Guys,

Depending on your design, I would use a propane torch and silver brazing.

Solder doesn't really join metal; it's an illusion.

Really? Damn, I guess that means none of our electronics work.

OK, Dave. Maybe I should have said that it works like magic....

Kind of like that magic black smoke inside the chips, then? OK, now I understand.

What kind of metal are your parts made from? If brass or steel, a high-temp silver solder would be good. For small parts, a propane torch should work, you need to get the joint red-hot. You can also use 1/16" brass brazing rod. Either way, you need brazing flux (borax) and a close-fitting joint, well cleaned and degreased before joining. If you need more heat, an air/acetylene torch would be good. Presto is the well-known brand, and you need a single hose and regulator. You can get a small MC tank (10 cu. in.) for a few dollars, it cost me $13 to exchange my empty for a full one just the other day. There are all sorts of low-temp solders, but they may not be reliable enough. I'd stay away from electrical and plumbing solders, they are best used as intended.
