Submerged Cell Project Project Page 14

I got the two fittings welded in. NOT the easiest thing to do, that's for sure, but they look decent.

Even got the inside welded in on the seam, that wasn't easy either, but that was because it was hard to get the TIG torch to point the right way. This side of it would have been far easier to do while it was apart, instead of welded altogether.

This area here was the hardest to do. I actually had to pull the tungsten further out than I wanted to so that I could get the area in-between the pipe fitting and the angle iron.

Here is everything that I have to do the inside wiring for the cell. As you can see it is two battery cables that you can get from walmart for about $6 I think. The lugs in the forground are what I'll be using when I cut the cables in half to better fit the tank. I'll have one that is short since the pass-through connections are right above one end. The other cable will eventually reach to the other end so that I can do the tank in a series of parallel sets. I want to eventually get the tank to about 7 sets so that I drop the voltage to about 2 volts. It'll be less than 3, so it will be likely to not creat heat from automobile voltage. If nothing else I'll just make 7 sets of however many plates, and then when I get more plates I'll increase the plates involved in each set.

Here you can see the back area of the tank where I put the pass-through connections. They are simply two stainless bolts welded together, head to head. I really wanted to find a good thick washer to weld onto the bottom to reduce leakage from around the bolts. I don't have close-ups of the electrical connections because at this moment I really don't like how they are done. Right now they are only simple anti-chaffe grommets, not grommets meant for pressure. I know that Chris had found some through one of his collegues, but I have yet to hear back from him. So for the time being I went out and bought some rubber washers, some clear tubing, and I'll try to use some silicone to seal it up. I don't like it, but unless some has any suggestions, I'm kinda stuck with this until I find something better.
