Home Anodizing Set-up

The task for the evening was to finish up bubblers for the ten tanks. I used 1/2" CPVC pipe and fittings to withstand the elevated temperatures. The bubblers are simply a manifold that lays in the bottom of the tank with holes to create bubbles that rise of the sides of the tank, agitating the solution. The challenge was to keep it compact and close to the bottom so it doesn't get in the way of parts hanging in the tank. Another challenge was getting the pipe through the side of the tank without it leaking. I thought about just going over the top, but I want to be able to use the water tight lids that came with the tanks. I ended up making bulkhead fittings out of some 1/2"NTP threaded adapters. I added a flange and seat for an O-Ring and changed the thread to 3/4-14 so I could use a locking collar on it. I forgot how much fun it is to turn PVC. The only thing left to do is drill the holes and hook the air pump up with Tygon tubing.
