Curtis,
The battery idea came from OCC thread or on line research can't remember which
Matt may be right about fooling the charger. I just hooked the leads from the charger to the battery and the leads from the battery to the tank. The charger would still cycle on and off once and a while.
I usually left each part in about 24 hours. Seemed to work for my system. Sometimes I would remove and hand wire brush at the 12 hour mark. Then put back in the tank.
I think the parts you did look pretty good. These are cast iron parts and may clean up different than mild steel parts. Yes surface rust can and will reform on the surface. I aggressively wire brushed the surfaces after coming out of the tank. Most of my parts were painted soon after cleaning too.
Looks to me your system is working well. Looking forward to seeing some cub parts.
Regards,
Chris
