I am about to buy a recitier, and I am having some problems deciding on what to buy. My parts are small, but there are bigger ones to. I am going to use the copy chrome (its on the way) and I have parts between 15 and 30 square amps. And they are not all the same. My first question is, do I need it to be exact. Can I use 2 amps if the square inches is around 42 square inches, which would require 1.5. Not sure on how exact you need to be. Also, when I calculate the surface area, do I calculate the entire surface area, or just the area that is not masked off. Or, do I calculate the entire surface area if I am only doing the front. Please help me so I don't buy the wrong rectifier. I am going to need between 1 amp and 4 amps, and I want one rectifier to do the job, looks like I need two, which I don't want to do. I have spent enough money already.
thanks, Kenny |

hello krsimulis. You should be pretty close on the amps to area ratio. I have the copychrome and I am using a 12v battery with a charger and light bulbs which works really well for me. I have plated up to 80 sq.in. You only need to figure the unmasked area. Hope this helps. lloyd

Glad to hear you are getting good results. I just posted another question about my first plate, it went all wrong. Are you plating aluminum, or other metals. Also, how big of a copy chrome kit are you using, and how many amps are you using. I might change over to a 12V system instead of a 6V system. Ill try anything right now. You know I didn't read your reply before I plated, wish I had because I calculated area wrong the first time. Let me know how you have your agitator submersed. I would really like to hear about your setup, it might help me figure out what I am doing wrong.
thanks, Kenny |

I just thought of a question I had right when I walked away. Lets say you have a flat piece, and you only want to plate one side. If I don't mask the other side with a laquer or anything, do I still need to count that in my area that I am calculating, or do I only count the area that will get plated. Or should I mask it. I also forgot to ask you where you got your bulbs from
thanks, Kenny |

kenny,
only calculate for the side you want to plate onto, also from the other post about the copper pipe only calculate the ouside area. if you calculate area into a piece that wont wind up getting plated anyway you will more than likely burn the plating. bill |
