Welding putty. Sold at any well-stocked welding supply store.


I tried "welding putty" among other terms in web searches and mostly
got references to epoxy-metal concoctions that seem rather ersatz.
I'll check with the local welding supply shops (Airgas and Trico in
Woodland) but I think dental soldering investment comes very close
to being what I need.

Thanks for writing!
