[quote=caswellsage]Your right on that count. I use the voltage for that kind of thing too. But I don't watch it as an indication of when the anodizing is done, which was, as I understood it supposed to be the reason for the calculator generating the voltage reading.

There is a misunderstanding if that is the way you took the purpose of the voltage calculation. It is given as a reference only. Using the voltage to determine anodizing time is only done when anodizing by PAR and maybe CV anodizing. There have been a number of posts discussing anodizing by PAR and CV but they are not recommended methods. Anodizing by the 720 rule uses the CD used and desired thickness of coating in mils to determine the anodizing time, not the projected peak voltage.


Sorry I've repeated these notes in a couple of threads. I also should have added "within the normal range of anodizing" which for me is betwen 4.5-12 A/sqft). I wasn't suggesting you supply current based only on the wire size to speed up the process.

To a novice, several of the things you have said are misleading if they do not understand the process to begin with. The standard LCD anodizing is done with 3-6 ASF and a 1:3 acid ratio. Many of us with experience use CD's outside of this standard but we also keep in mind that we're dealing with people just learning. The multiply by 5 amp-minutes and divide by whatever amps your PS and connection will handle to get the time of the run you want is careless when dealing with novices. I know these are not your exact words or how you meant it but you understand what you are doing and they don't. I understand that you've taken the 720 amp-minutes per square foot and broken it down to 5 amp-minutes per square inch. It's when you get to choosing the amp setting that I see a problem. Cameraman has experience and you see the confusion he had. I had to reread the post several times myself to see what you were doing. Imagine someone not familiar with the process.
