I have decided to make a different kind of vent - a tube with a top-mounted
vent. I know how to hold a tube vertical and scribe it to a curved surface..
Then I'm going to cut out the tube and grind it until it fits the tank end
closely, then hold it in place and scribe around the tube and cut a bit inside
the scribe line, then smooth the cut a bit and then weld the tube in place..
