Re: Rig for Anodizing Pen Barrels?
Sounds like a good choice of connection wire!
The aluminum to copper connection is not too bad as long as it is out of the acid.
You'll need to have a good solid connection... not just parts hanging on a hook. As the ano layers build (both the parts and the wires) you'll loose the connection (ano layer is an insulator). You'll see this as wires that take dye easily, but the parts do not.
The most common problem with beginners is loss of connection.
I would think the smaller PS would be adequate, but you really should be measuring the total surface area, and multiplying by your target CD to get the required amps. 6 amps per sq. ft. is a good CD (current density). At that CD, the time in the tank calcs out to 1-1/2 hrs for .75mil ano build.
Post some pics when you're done. I think you're well on your way now.
