[PSUBS-MAILIST] MBT vent tube

[Rick Patton via Personal_Submersibles]

Well I fabricated a jig on my fab table using 3/16” X 1 1/2” flat bar, packed the 1” SS tube with sand, welded ends on it, said a few prayers and went for it. I first tried cold bending it but needed a much stronger jig for that so I pulled out my rose bud and hot bent it and it worked great! Now I have a lot of buffing to do to make it look pretty again.
