Catch can fabricated out of aluminum for a supermoto bike. 1/8 inch aluminum tube, 1/8 inch plate for the ends. Tapped tube fitting for clear drain hose. I drew a yellow box around the welds as they are hard to see, (this is a welding forum!) 3/32 red tungsten - 135 amps, pulse, no filler. - Lincoln PT 185. - Only downer of the whole thing was not having a rotary table. Starting, stopping, then turning the piece sucks.
