Hello all,

Here's a link to a short-ish video of my first serious efforts and what I'm learning along the way. Comments and constructive criticisms are welcome! Thanks, Athopi

Thanks, Aka, my new bubbler will have the inlet at the bottom.

I redid some things.

I replaced my copper wires inside the tank with SS welding rod- hard to bend!- and replaced the wood and wire plate wrappers with small zipties. I also replaced the smaller wires from the power supply right to the top lead post, bypassing the PWM, of the tank with 10 awg wire to new 1/4"  SS bolt lead posts.

I started with 2 plates and got nearly as much gas as with the 7 plates! They were spaced 1/16th" and drew 12 amps. Again, I'm getting orange scum. I used a full teaspoon of baking soda for the electrolyte and 1 gal. of tap water.

Next I added 4 more plates at the same spacing and the thing drew 24+/- amps and gas production was a little more than with the 7 plates. The current draw heated my lead posts so hot that they started to melt through the plastic lid of my container! I dowsed the leadpost with water from the bubbler and the - one was so hot it boiled the water for about 10 or so seconds.

Also, I acquired a roll of ss about 3 1/2" wide by .01" and cut off 7 pieces 4" long with the intention of making new plates. The processes of cutting, drilling and sanding have basically made them so warped, each in different areas, that they will be unusable due to shorting out.

My next steps will be to increase the spacing back to 1/8th" and reduce baking soda by 75% to get the amp draw back down. I'll try to find some distilled water to replace my mineral-high tap water to get rid of the scum.

I don't know what I can do to keep from bending and warping the new ss from the roll so that I end up with flat plates with nice, clean spacing... my shop is set up for woodworking. I replaced the wood blade to a metal cutting blade on my sliding cut-off saw to cut the plates, but it leaves flash on the cut edge the width of the blade. That was no problem with the thicker wall switch plates, but cutting them and then removing the flash from the thinner plates creates a lot of heat and warps them. Drilling the 1/4" holes also warps them.

Any ideas, anyone?
