Power supply for aluminum etching/anodizing?

[atalon]

Anyone have suggestions for an inexpensive power supply for etching/anodizing? Will be used for aluminum.

What kind of juice do you need?

You can do it with a 12vdc car battery charger (manual type) or you can PM and I have a bunch of power supplies 5vd,12vdc,24vdc and up from my father's estate that I am liquidating. I can hook you up! I am just 3 miles outside terre haute (north).

Got an unused computer ATX power supply? Read the label to see if it puts out the right combination of voltage and current and if so, sic this little gem on it.

I vaguely remember hearing about a place where you prepay for a power supply, wait months and months, and it just never shows up.

That depends what your requirements are. IIRC good AL etching machines use AC current. You can make your own variable power AC power supply by using an AC transformer connected to a wall outlet and adding a light dimmer in-line on the high-side. Turning the light dimmer up/down turns down the output side by roughly the same proportion.

DC power supplies are much more readily available and you likely can make the same variable power modification with a light dimmer on the input side.

Humor? It was a simple one word question...hence the question mark at the end.

Relax.

I was referring to my own post which you quoted.

Just sold off a lot of 8 or 9 power supplies at auction last week. If anyone is still looking PM me before I run out. I think I am down to 15-20 or so now.
