New heavy duty, flint glass, round, 6" OD X 7-3/4" high battery jars from Flinn Scientific at a cost of $50.00 each, including shipping will be used for the new chrome tanks. New holding, masking fixtures will be used to chrome steel, brass & aluminum cylinder ID's. New battery jar covers were machined to fit both the old & new type battery jars. More details to follow on how to reverse the current when etching steel cylinders before chroming.

Jim,

What material do you use to machine the covers from?

Brian,

 

PVC can be used for any plastic part in the chrome tank. Brass parts should be made from #360 free machining brass. Alligator clips are Mueller 25C 75-amp types with 25C rubber insulators.
