Harbor Freight is having a sale. (I got a fuel-pressure test kit that has Bosch CIS fittings in it. $70. The diesel compression tester is again on sale at $17.) But what was particularly interesting was a 1# box of Alumiweld (http://www.alumiweld.com) rods. These are some kind of zinc alloy meant for brazing aluminum and pot metal. $12, usually it's more like $20 there, or $30 elsewhere. The printed instructions were fragmentary and the importance of a clean dedicated stainless steel (no substitutions!) cleaning brush was not clear. I think I may go back and get a brush, and maybe another 1# box of rods. This is the stuff that would probably have been very good for fixing that window regulator.
