Dunno for sure, but overleaf from the title page of "The Model Engineer's

Didn't T-Nut call himself Tubal Cain initially? Same guy? I know that
Tubal Cain is a secret Freemason name having to do with metalworking, so
there may be several who have used that handle, but who knows? I do miss
T-Nut.

Presumably Freemasonry picked the name up from the original, i.e.
Genesis 4:22: "Zillah bore Tubal-cain; he was the forger of all
instruments of bronze and iron." http://bible.cc/genesis/4-22.htm
also translates part of that as "the father of every maker of cutting
instruments of brass and iron" and "an instructer of every artificer
in brass and iron".

I just got and read "Soldering and Brazing" by Tubal Cain, which had
been recommended on RCM. It was very useful, and well worth the $13.00
(including shipping by Royal mail) it cost me.
....
Soldering and Brazing is #9 is a whole series of 33 practical books.
Wonder if they are all that good.
