Re: question regarding prepped parts
The parts can sit a week or two without oxidizing much. The way I do parts like that is to clean, strip and buff out, then degrease and clean just before the run. If you buff out a part to a high shine, degrease and clean to pass a water break test, you can skip the deox step. The deox/desmut is for taking off natural oxidation and smut problematic materials. If the part is fresh machined or polished, it is usually unnecessary.
The higher CD's or a sudden surge in current will definitely test your connections. If ramping the current causes you to loose connection, then you don't have enough spring tension on the connections. I would try going to a 12g or 14g wire if it will work on your parts. It will carry current better, give you more contact surface to the part and hopefully much more spring tension to hold the part and connection. If you have a good connection to the part, the agitation should not effect it. When I do smaller parts, they dance in the flow of electrolyte.
Did you find out the main cause or causes to your problems or did you change too many things at once to know which had what effect?
