Default Re: help getting coverage with irregular part

update!

For the throttle shafts, I did as you suggested, and dailed the amps way back, then left it in there for abour 50 minutes, while moving the anodes 3 times. That left me with a very nicely plated part. I chromated it and it turned out super. THANK YOU!

I have to ask you something that I have seen you mention before. With my copy cad set-up... It seems like when I don't have brightener in there, everything turns out really dark, and does not chromate well at all. I noticed you mentioned that you should never use brightener if chromating the part... well it must be something with the yellow chromate that I am using, but it does not rub off after. in fact, it really stays put. it must be something in the particular chomate I am using, because you are THE MAN when it comes to the caswell stuff. Anyways, I thought I should mention that because using brightener is the ONLY way my parts turn out worth a darn.

Oh, and the acid salts and yellow chromate are the ones I emailed you the PDF file of, back in October or so.

When I take the part out of the copy cad, then dip it for about 2 - 8 seconds in the acid salts, the part really shines up, then into the chromate. If I just chromate out of the copy cad, it does not brighten up the same.

Man, I never wanted to be a plater, just wanted to shine up the stuff I sell, but it really depends on alot of trial and error, that is FOR SURE!!
