I used to be a Chrome Plater for TRW's Engine components division. I put the round peg in the round hole as fast as I could, a monkey could do the job but it paid well. Chrome plating intake and exhaust valves for GM, ford, Catipillar valves sucked, they were over a foot long and the shaft was 1/2" in diameter.
the process we used was an electric rack plater: dip the part in 2-3 different strength acid tanks to clean and prep the metal and than apply the electric charge to the valve when it dipped into the plating tank, large lead ingots with copper running through them would donate the chrome molecules and they would migrate to the valves...thickness of the chrome was related to how long the electric charge was on...
all i know is I like working for Intel a lot better:D
hmmm...have you priced having the parts you want chromed locally? it would be pretty cool to say that chromed your own parts but I know I spent a lot of time polishing valve stems that the chrome got screwed up on. those were nice round parts that we could get the defective chrome off easily. the thing I would be leary of would be having the chrome get screwed up on some difficult to find parts...
watching the video it looks like pretty much the same process we used (only miniture) maybe make sure you use a brand new battery..., but we could vary the current flow depending on the time/thickness of the finish we needed.
yeah ... I'm thinking time here as well ... so I dont really think I have the time to do this .. I want to chrome some of the small things like wiper arms , and blades .. but maybe I'm just better off "farming " it out ?
they offer a powder coating kit as well ... and all you need is an oven .. I might do that , as i'm sure this is what most of "small business" community is doing .
I still have a 2WD to build as well ... so this is my thought process .
