hi randy

some of the lights are a little wonky on the magnets ... i usually tell people when the stuff they plate
starts getting "dark" ( instead of greyish, it is dark-greyish / blackish ) it is time to turn it off
because they are plating other "stuff" not just the silver ... as long as they stick it in a non-metalic container
when they run it they are good to go, a metal container will end up electro-plated silver ...

oh, your magnet will hold around 32troy oz of silver on it, it would have paid for itself 12-13 times over if you let it get real-full

have fun !
(and thanks ! )

So, let's round off and say 30 oz. of silver at $30 per.

$900 return on a $50 investment ain't too shabby. Is it?

Yes, I noticed the lights aren't perfect but you can still tell.
When you first connect a clean cell to the wall wart, the red light glows brightly. When you submerge it in the fixer, it is barely aglow.
As the silver gets pulled out of the fixer, the red light gets a bit brighter.

I also watch the color of the silver building up on the plate. It looks like sand. About the color of sand, too.
I pulled mine out when the sand started getting darker.

My darkroom is in the basement. I can look in every so often as I go down to do laundry and stuff. The intensity of the light will give me enough information to know when to go look at the condition of the "sand" inside the cell.

John:

You might consider copying Randy's posts and your responding posts to the thread you have going about the Silver Magnet.

And yes, I am still trying to figure out how I could make one work with my temporary darkroom setup..
