Thermocouples

Still no testing to report but in the interest of keeping the blog alive, I thought I'd share a minor little tidbit.

If you want to measure the temperature of a metal part, say a combustion chamber, it can be hard to get a TC bead in good contact with the metal.   A better approach is to actually weld the TC wires to the part.   Through the magic of TCs, you can actually weld the two wires independantly.   Tonight I thought I'd try it out on a piece of scrap stainless tube with the TIG welder my wife bought me last year.

It turned out to be much easier than I thought it would be. (Please ignore the practice spots :)
