Electroplated Coils? Hmmm interesting...

Making Coils with electroplaed segments of copper. NEAT-O!

Hello there,

Had a thought the other day.
"Lets electroplate some quarters!"
So I now have some copper coated quarters. I thought it looked real cool.lol. Now that I can electroplate copper onto stuff I thought "Could you make a perfect coil by electroplating copper up in a spiral fashion?"

So what came in mind was if you started out with a base copper that was a coil shaped oval with a notch cut out. Sort of like a "U" and then spray painted all over it, except a small spot on the one end of the "U". So what I was thinking next to do was electroplate on some more copper but electroplate it so far but not have it touch to form a circle(you want it not to make a circle). Now I know you can't electroplate copper on spray paint... it just doesn't work. So I was thinking of using copper "dust." Like very fine grain copper and "sprinkle" it on so then it can electroplate the "dust" togather and build it up. Forming a new ring. Now spray paint again. And Repeat!

The benefits to this would be that you could use ANY fairly pure copper source. You can get copper at its scrap value and use it.

The ONLY problem I see. Is I haven't tried it yet! So I don't know how well this would work. I don't know what problems would arise from it either. With that said, I am asking anyone who's done stuff like this before to please speak up. Anyone who's had experience electroplating, too. I've done electroplating before. Though it was only 1 time.lol.

And electroplating isn't that hard. I made my own electolyte from battery acid so its not too complicated. Though I don't know it could be illegal or harmful to the environment. I would also like those two concerns to be address if you know the answers.

Ok I know I said a lot here. Its very "if-y" so thats why I put it in the newbie's section. And my explaination's are never too great so if your confused, just say. I'll try to make some pictures if your really lost.

This is what I was thinking... Hopefully makes more sense now...

Look at it in my files... I think it was shrunk when put in, by 80%!

Randy,

I have in possession some PCB board that is '3oz'. At some time, I plan on cutting some stators with a CNC machine. The idea is to cut matching spirals on each side of the board and build an extremely low gap axial generator stator. This would need to be tested to see if it made economic sense.

If it did,one could 'etch' a PCB board and plate copper to it. Actually, one would 'un-plate' where they didn't want copper (etch) then plate until the desired current capacity was met.

Good luck,

Ron

Printed circuit motors are common in the servo and special purpose world, but they offer little advantage unless you are looking for very low inertia.

Have a try by all means but you will soon find that electroplating is not as simple as you first suppose.

Ed Lenz at Windstuffnow had something like this I beleive.  I looked for them just now so that I could put in a link, but I can't see them.  I presume he's stopped selling them.

I think he had 9 coils per board and the idea was that you stack several boards to give the correct equivalent wire thickness.

Well I'm not so much try to make it like the PCB's that Ed and I think others have made. I'm thinking more of building upon each turn so its still a thin coil(not as thin as PCB) but every turn is exactly the same size and gets the same flux.

Would it hurt if the copper "track"'s "leg" was as wide as most coils'legs are now(like 3/4")?

I'm probably going to test it out next weekend. :-)

An interesting idea if you can make it work.  I've got a couple hundred pounds of native copper of various sizes that I found over the years.  In fact I found one of three or four ounces weight yesterday on the road.  Why the road?  The county crushes rock from the old mine waste piles and spreads it on the roads.  Voila, copper bearing gravel roads.  Of course, it also helps that I work occasionally for a mining engineer, who has one of his activities being capping of old copper mine shafts.  Now, if I could just get the silver to deposit on a different surface than the copper.

Ok.. well I am trying it.

Tonight I'm making my Copper Sulfate. I spray painted a peice of copper. All that I am trying to night is to see if my paint will work or if any sulfuric acid will seem to "eat" it away. So what I am just doing is trying to electroplate a ring onto a flat piece of painted copper. I'm gonna probably use pencil graphite(not the best but I dont feel like sanding or grinding for several hours to get enough copper dust.

Got to go - check the Blue liquid ;-)

Ok, It didn't work the greattest. :-(

What my plan was to do was to first spraypaint a piece of steel with paint. Then put it in the solution to see if it reacts or if any copper is placed on the paint(no electricity is applied). Also I'll know if there are any gaps in the paint. Just knowing my chemistry Iron is more reactive than copper. So... Fe + CuSO4 --> FeSO4 + Cu. So basicily the iron will replace the copper and the copper will be left where the iron was. Also, If I see bubbles then I'll know if it was reacting with the Sulfuric acid.

So I painted a rod of gal. steel. I made it so half of it was sticking in the solution and the very top was out in the air not coated by paint. So this made it possible to add electrcity too.

Then I put it in and after about 20 seconds. VERY SMALL bubbles started to forum. This was the first indication that it wasn't going to work. Then I applied some electrcity and the entire plate(all of it, meaning the paint) was coated with little tiny bubbles, more than before. So I know that something was reacting or atleast the paint was conducting electricity. Maybe it wasn't dry enough :-|

So as of now I'm a bit stumped. I figure its possible but we'll see. I'm thinking of using the epoxy spray paint now. I don't know if that will make a difference or not. A big problem with all this is TIME. If it takes 12 hours to get a good dry spray paint then, you can only do 2 "turns" a day! If you have 40 to do. Thats 20 days! Or if your making 120 turns- Thats about 60 days! Or almost 2 months. So Pretty much I'd have to set up a system that did all the coils at once. Hmmm the possiblities.

You might consider shellac or varnish that can be baked out.

OK. I'll look into it. I don't have anymore copper sulfate so for now I can't do it. I can only find 50 pound bags of it. Which I don't even need 1 pound. So we'll see when ever I get around it to.

Ok, This is my status...

1)All materials collected(Sulfuric acid, Epoxy paint, copper, battery charger, containers, goggles, Distilled water)

2)Testing will start tomorrow night
    a)Test: Epoxy paint reacts with Sulfuric acid?
    b)Test: Epoxy paint reacts with sulfuric acid under electrical charge?
    c)Test: Copper Dust be electroplated together?

3) Then I will try to make a coil
    a) See if it is possible to make similar "turns" and make duplications of coil

I will let you know of any updates.
