Been reading a bunch over the last few weeks waiting for some parts to trickle in for the completion of my bench. I purchased the 20gal Kit from Caswell and just have a couple of questions that I wonder if the answer even matters.
1) For the ano tank itself, is it beneficial to be able to move the cathodes closer to the anode when the parts are not utilizing the whole tank or should I just stick two sheets of lead material at either end and call it good? Secondly to this question, if it doesn't much matter, will having "less" distance for the current to travel allow for lower voltage use?
2) Is there a solution mixture that would allow for faster anodizing times using the caswell 30 amp power supply? Reason I ask is because I have a spare 30gal (20gal effective volume) tank that would be handy to set up as a secondary bath for our production runs. For the most part we will be anodizing custom colors to order but there are a couple times a year where we run 2500 smaller pieces at a time. I could have two normal speed baths but was curious if a stronger concentration with higher amperage would yield faster cycle times through the bath.
3) On the bigger production run stuff, a chiller would most likely be necessary as the surface area of a full rack would be 443"^2 and if I wanted any sort of "normal" time I assume the amps/volt level would require a cooler. I read some stuff about titanium cores rotting out and one person mentioned to remove the ground from the chiller. Are we talking the ground that would be connected to a core and attached to the chassis of the unit OR are we talking the ground on the 3 prong wall plug? If it matters, I have a little giant 14.2gpm MD-HC4 pump in transit to me. That alone is probably not enough flow to stay cool on large batch sizes, correct?
4)short of bringing the power supply into a store with me, does anyone know what size banana plugs the back of the 30amp unit uses? I want to make a nice harness but I can't find the specs of what size the plug is for the main + and -
I will post some pictures of the bench thus far once my phone finished charging.
