Deposit Thicker Copper on Glass with DIY Electrode Cooling

[dlgoff]

I wanted to deposit thicker layers of copper on glass with the deposition system I put together, meaning I would need to keep current flowing through the tungsten heating element longer. But with 70 or 80 amps @5 volts, the electrodes wouldn't be able to survive the heat generated. So my solution was, circulate cold water through them. Very simple and cheap. One small cut-down styrofoam cooler, small metal "pot" ~2 1/2 cups, some plastic tubing, a small fountain pump, and ice. Here's a couple of pictures; the electrodes being cooled and the circulating water chiller.

Looks like you're making moonshine to me...

I'll drink to that!

BTW: This thing works really well. I've been able to deposit really thick layers of copper on glass now.

Yes, flux capacitors do need a pretty thick layer of copper.
any chance of showing the pictures of the deLorean out back.
