Smile Re: Low Voltage

Hi All,

Thanks for all your replies. Will try some small changes on the next piece I anodize.

Surface area was a guess as the part has complex shape. I used 60sq” as part size. Trying to figure out how to post picture, then surface area would be visible to all. I was trying for 6ASF and 1 mil thickness. Tank temp was 70° at start and 68° at finish (working outside and timed it for sunset in effort to control temp).

Agitation used filtered shop air to alum tubing coil with 1/16” holes, maybe too much, as part was swaying in tank.

The peak voltage 10.1 at two hours run time. Just set tank up, one part battery acid to one part distilled water; checked with battery hydrometer was 1100. Using 1/8” alum tig welding wire to hang piece.

I’m please with the color of first real piece, now will try 4.5ASF and shorter run time. My results have been rewarding for the little experience I have, maybe I’m worrying too much about voltage.

Thanks again, Jim
