Yep, that duct tape is pretty good stuff. I always carry some with me to keep things together and it has come in handy on several occasions.
It certainly is possible that the black tape keeps direct contact from occurring between the copper manifold and the TC. Do you think that Rossi was using the insulation to hold the TC to the nut? That would seem to be a little unreliable.

Ah. You mean the purpose is to keep the TC in contact with the nut only, and not to conduct too much heat from the manifold. I expect you are right. Black electrical tape is pretty good thermal insulation. So is duct tape, which is similar. Generally speaking, a good electrical insulator is also good at thermal insulation. By the way, Heckert referred to "duct tape" yesterday. I think he referred to what Americans would call "adhesive tape" or "Scotch tape." Duct tape in the U.S. is heavy gray ultra sticky stuff: http://en.wikipedia.org/wiki/Duct_tape It is used for all-purpose everything repairs. It was used in Apollo 13 to avoid catastrophe and make an air filter. I have a 20-year-old car in Japan which is held together with the stuff. - Jed
