Other hobby teminology-a riddle of sorts

[doctorwayne]

Oakum is the stuff we use to stuff in the bell joints of cast iron drain pipe - pack it in place by hand, then set it using a hammer and cold chisel. I'd guess in Pete's language, it'd be used to make tight the joints in the planking of wooden ships. As for "make fast", I'd guess it's derived from "fasten", and simply means "make secure" as in tying-up a boat or even "battening down the hatches".
I've got an obscure one for any woodworkers out there: jigoku-kusabi. Anybody wanna take a guess?

I spent my working life in a steel plant, and like most industries, it had its own teminology: bustle pipe, downcomer, stripper, mud gun, bottom digger, scarfer, bloom, tap hole, runner, piping, hooker, recuperator, and manipulator, to name a few.
