Electroplating copper on stainless

I would expect this topic to have multiple posts by the same person showing us how to do something. If there are pictures, let pint_o_shine know and he can host them for you.

Oh hell yeah, I'd go for it then. Might do it on mine as well. Was thinking of using copper mesh for such a large job as a full keg. Wrap it around the inside of the drum that I plan on using and hold it in place around the rim with copper wire bent into a hook shape. Then drop the keg down the center. Would this be beneficial or just more head ache?

It doesn't matter what the material is there, it's all about how much of the copper is in the solution, doesn't matter a lick really about what form it is in as long as the sacrificial anode can replace what's being lost... that's why it's important to get the voltage correct for different sized jobs and bath make ups...

Mesh might fall apart too fast, I'd be inclined to stick with scrap copper pipe. An Anode for a full keg might need to be circular.... I'll have to experiment, it's not going to be simple I think.

How many kegs will it take to plate one with copper???

I once got a boat load of copper sulfate when playing around with some computer pins in ammonium nitrate and sulphuric acid...

Who's video is that? Thanks for posting it... if he had some neutral gas blowing on that I might believe it would stick a long time

There's a lot of empty lines in your sig AE can you shorten it up? I really notice scrolling on the netbook, would appreciate it. Thanks...

Edit NM... it's no the sig... duh, sorry

Thanks AE... made a huge difference..

LOL @ Snuffy's vid I thought it looked familiar.. and it was... he is getting a nice plate there for sure... . A plastic cup with a neutral gas around the brush can help with oddball oxide build up... like a tig or gas mig welder... You don't necessarily notice at the time but it can prevent peeling later since the process doesn't have the oxygen protection provided by immersion.

The goal was to get enough copper on the surface that the solder would flow instead of bead up. It worked. We'll see how it holds up to use, but it feels strong enough. If you go back and look at the pictures, you'll see that it had oxidized where the solder didn't cover the plating.

Those ratty old flannel shirts give me away every time.

CRAP: Is this right? I really wanted to plate over the bowl rim that I have soldered to a stock pot. Partially to cover where I overheated it and partially to line the holes that need to be filled where I burnt the flux.
Don't even ask :oops:
Can you plate over solder?

Yeah it's right, it takes an annoying process to plate to tin anyhow and you couldn't jump to copper. It would be a nickel then copper plating process normally if not zinc-nickel-copper.

Even if this won't work for you this time, there's always another build.

So I gave it a go plating some 3" tri-clamp ferrules per Ugly's method. I used all the optional materials as I already had them on hand. First try was a spoon and it worked great. Feeling confident, the ferrules were next. I had 3 to do, and the first went well with the entire piece adhering tightly. #2 was spotty and #3 was only about 1/2 covered. There was a large amount of brownish-black buildup and furious bubbling where the copper wasn't sticking .

After some quick tech support some Ugly we thought the ferrules were too close to the copper anode. The bread dish was large enough to accommodate the spoon, but the ferrules were much closer because of their shape. So I swapped the bread dish for a larger plastic tub and tried again. This time there was about 8" between anode and ferrule. Here's the result:

They're not quite as shiny as Ugly's, and there are a few bald patches, but I think they'll work. If not somebody please tell me before I try to solder them. I can plate them some more. BTW, I set one on a vinegar soaked towel for a few seconds and didn't rinse it. It ate the copper away. Is that right, or do they need more layers of plating?
