What this video covers

Fabricating custom stainless steel water tank vents for the fishing trawler *BrewPeg* requires welding a threaded rod and nut assembly into a heavy-wall stainless pipe to create a sealable, adjustable lid.0:39 The design uses a smaller-diameter pipe as the upright and a larger-diameter pipe section as the cap, with a 3mm nitrile rubber gasket providing a watertight seal.3:01 To center the threaded rod within the pipe without a lathe, the builder uses a makeshift "desk lathe" by spinning the rod in a battery drill while hand-filing or positioning the components.30:27 The assembly is TIG-welded using high-amperage, high-speed passes to prevent heat-induced warping of the 3mm stainless steel.24:07 Once completed, the vent is integrated into the foredeck by cutting a circular hole, welding the vent to a stainless plate, and then welding that plate flush to the deck surface.35:15 The resulting vent allows air exchange for the water tank while protecting against water ingress in heavy seas.2:39
