Oh well now, this is fun. You're eager to start a dicksize war and
I'm paralyzed by not caring very much.

The guy wasn't invited to address my welding class because he drove a
forklift, but because he was a very successful welder and diver. You
may want to know about the inspection procedures on nulear subs, but
I don't. I don't care what kind of rod they use welding submarine
oil pipelines, or bridges, or tanks, or tunnels, or the fillings in
whales' teeth. Not interested.

If you want to learn how such stuff is done, sorry, dude, you'll have
to ask someone else. Maybe read a nice book.

But you might want to make less noise about it. You sound like a
framer who doesn't believe cabinetmakers exist.
