How to Set up a Simple Home Electroplating System


A discussion started in 1999 but continuing through 2018

1999

Q. HI, MY NAME IS RAY.

AS A HOBBY I RECONDITION OLDER MOTORCYCLES. I FREQUENTLY HAVE THE NEED TO CHROME PLATE OR NICKEL PLATE SOME COMPONENTS. I AM WONDERING IF IT IS FEASIBLE TO SET UP A PLATING SYSTEM IN MY GARAGE? I NEED TO KNOW WHAT A SIMPLE START-UP SYSTEM WOULD TAKE. I UNDERSTAND ONLY THE BASIC CONCEPT OF HOW ELECTROPLATING WORKS SO PLEASE BE SIMPLISTIC ON ME. HOPEFULLY WAITING!

1999

A. Our FAQs "How Electroplating Works" and "Introduction to Chrome Plating" may help you, Raymond -- please give them a look! But unfortunately it may prove impractical for you to make a business out of chrome plating in your garage due to OSHA safety regulations and EPA waste disposal regulations.

The plating industry was the country's very first EPA regulated industry, and the burden of compliance is heavy. Further, chrome plating solution is carcinogenic (think "Erin Brockovich" [link is to movie info at Amazon] and hexavalent chrome). If you charge a friend a few dollars to plate something, you are in the business and possibly subject to reporting and disposal requirements. So please start by investigating the regs before buying anything and becoming forever responsible for it.

Why do we say "forever responsible"? Picture a company that has generated toxic waste. They hire a contractor for disposal which turns out to be an evil one which dumps the waste in a swamp, pockets the disposal fees, dissolves the corporation and disappears -- leaving the public to pay the cleanup cost as in days of old? To address that problem the EPA came up with a simple rule: it doesn't matter who you ship hazardous waste to, or how much you paid to get rid of it, or how long ago it was: the "generator" of the waste remains responsible for it forever no matter what! Then add their 'joint & several liability' clause and you realize that if they can't separate your waste from others' wastes it's not a good thing for you, it's a very bad thing :-(

Best of luck!

$29 to $80 kits chrome plating kits

2000

Q. Funny, I have seen chrome plating kits in motorcycle mags. One long ago for 25 bucks. Recently for more but I can't remember where or how much. I want to plate the slides in Amal carbs. I am sure that this would improve their reliability. If you have any info on who would do this, please let me know.

A. Hi PRK,

Yes, you saw plating kits for about $29 some years ago from J.C. Whitney -- today Eastwood offers them at around $80, but these were/are zinc plating kits not chrome plating kits. Again, chrome is a heavily regulated carcinogenic toxin.

If you wish to investigate entry level electroplating, you could also contact a supplier of brush plating equipment and small systems. Just googling "hobby plating supplier" will find them.

But if you spend some more time at this site, reviewing letters from earlier posters with similar interests to yours, you'll see why we urge caution and investigating the regulations before you buy any chemicals (especially chrome) and become responsible for them. In America, once you use the plating chemicals (probably even once you open the bag), you are the "waste generator" and they become your waste forever! No matter how much you pay anyone to take, treat, or dispose of them, they are still your responsibility even 50 years from now and more. So look before you leap :-)

Good luck!

Q. I am curious how well these home brush-based chroming kits. In particular, I have an old 1970's bicycle with chrome forks and rear stays, and chrome lugs. The chrome is almost intact, but there are lots of sand-sized rust specs in places.

If I can clean off the sand-sized rust specs, what will be the result of chroming using one of these home kits ($30 from JC Whitney, etc.) I am not looking for a perfect job, I'm looking for something that looks good at 5 feet and protects the finish so it doesn't rust anytime soon.

A. James, brush plating and minimal tank plating is clearly possible; we mentioned and linked some suppliers already. But you seem to be speaking of an automobile bumper or some other very big copper-nickel-chrome plated item, and this would be a large undertaking both in how much you'd need to learn to apply all the layers, and the effort of successfully plating such a large item with a tiny stylus. I think you may want to start smaller and with a chrome-free plating solution.

Donald, I don't think JC Whitney offers one anymore but, as noted, there is a $80 tin-zinc plating system available from The Eastwood Company.

Our site's focus is primarily industrial, where people typically spend thousands of times that much for a plating installation. We're certainly not trying to talk you out of a $75 investment in learning and experimentation. But quality plating with a real plating outfit is hard. Quality plating with a toy can be a joke. To chrome plate James' bumper with a plating cell like the kits you refer to, would require thousands upon thousands of AA batteries. Your job is smaller, but look up Faraday's Law of Electrolysis and figure out how many hundred batteries you would need. And then you still have the issue of preparing the substrate so that your plating won't peel off, the fact that it's a chrome substitute not really chrome and it won't quite match, etc. It's a big job.

Our concern isn't whether you spend $75 -- please do! And please try the plating experiments in our FAQ "How Plating Works", which will cost you nothing at all. Good luck; we just don't want to tempt you out onto a slippery slope that can pollute, be very costly, or possibly beset you with fines. Good luck!

A. I use a home kit frequently to chrome aluminum pieces. Just have to treat it first - remove the oxide layer and apply a layer of zinc -- I use a zincate solution.

Dangers are overstated!

2005

thumbsdownThis is just a comment, you can ignore it, but I don't think you will be able to based on the NUMEROUS posts in the past.

This site DEFINITELY overstates dangers of home plating, I personally believe the reason is that if everyone found out how EASY it is to plate at home, the commercial shops would lose, LARGE...including yourselves.

I have been plating at home for years now, no problems. I find that there are dangers to EVERYTHING that a do-it-yourselfer must be careful of. Your attitude on this subject is "Don't get into woodworking at home, you could cut your hands of what with all those power tools." or "Don't get into painting at home what with all those fumes".

Honestly, RUBBISH!

How about doing us and yourself a favor and start posting educational responses to peoples questions and drop the 'tude.

Go ahead, blast me too. Oh yeah, I do take my waste to proper waste management facilities. Any "SHOP" can make mistakes as easily as a home do-it-yourselfer.

Jim: we are happy to print your opinion and everybody's opinion, that's what a public forum is for. Here on this site is all the space you want, free of charge, to tell people anything you want about what you've learned in your years of plating at home.

You are right that I won't ignore your posting; I'm the site host and my job is to respond to postings not to ignore them. But I don't own or manage a plating shop, never did, never will; and your claims of ulterior motive just paint you as a petulant adolescent. Grow up.

This free site includes thousands of pages of information for students, plating book reviews, links to plating educational societies and training sessions, a calendar of events of where you can attend free plating lectures, ASTM plating standards and free MIL standards, addresses of free plating libraries, and tens of thousands of highly detailed responses to plating questions and problems. We never censor postings (except ads and ad-hominem remarks), so please share your plating experience instead of whining that others aren't sharing theirs.

Hi Tyrone: This isn't the Hotel California; if you've "had it" you can leave any time you like. But you, too, are welcome to tell people how to do electroplating at home. Here is all the space you want, a very large audience, and it won't cost you a dime. So get to it -- or is your posting just vacuous bitching?

Your analogy that our warnings are similar to telling people not to drive because they might get in an accident is perfect, thank you! The government requires that every driver be trained, tested, and licensed; the government requires that every vehicle be registered, inspected, and insured. If you don't comply, you'll be fined and in egregious cases jailed.

Similarly, the government demands training, testing, and licensing of all plating shops and their employees. Operate without the registrations, the blood tests showing that the employees are safe, the discharge permits, the testing of bath surface tensions, the ampere-hour logs, the waste accumulation records, the manifesting, the annual hazwoper certification, or without advising your neighbors of the materials that you have on hand (Community Right-To-Know law), and you are subject to fines or even jail time. I know two plating shop managers who did hard time.

Yes, you can probably illegally operate a small plating business and stay below the radar, just as you can probably get away with driving without a license, registration, or insurance. And some of the regulations don't apply if it's a hobby and you never take a dollar for plated product or your plating service.

But we had a 'cancer cluster' in my town so everything in the neighborhood was deeply investigated; if a neighborhood child contracts cancer for any of a thousand reasons and her parents find out that you were chrome plating in your garage, discharging carcinogenic fumes into the air, God help you. It's not likely to happen, but if it does, your life as you knew it is over.

thumbs up signChrome plating in your garage! Cover ups and conspiracies!
I was born into a custom chrome plating business. I worked there as a young teenager. I'm in my mid fifties now. Custom chrome plating is all I have ever done. I run the business. I know every aspect. I have done everything. Metal stripping, polishing, bead blasting, cleaning and activating for plating, cyanide copper plating, acid copper plating, nickel plating, chrome plating, customer relations, reporting to various agencies (EPA, DNR, local sewer districts, Etc.) All accounting and payroll. I know I am missing a few things, but I think Ted will understand.

And now Tyrone says its a big cover up to deny people a chance to make millions in their garage. Oh Lord! Maybe we need a Canadian disposal place that doesn't require permits and testing as inferred in an earlier comment. To think all the years wasted when I could have done it in my garage and made millions!

Is it possible to do touch-up?

2006

Q. To MW Jansen: how about some details. I want to touch up a couple spots of chrome sheet metal.

Volts, amps, source of solution, what are anode and cathode materials, temperature, etc?

Q. Hi to those of you who will answer questions and not whine. I was wanting to replate the pot metal parts from my 68 El Camino. What's the best way to prep the parts with moderate pitting, and should they be treated as an aluminum part in the plating process? Last but not least if you're not willing to eat it or drink it, then treat it as a nasty substance be responsible. Dumping it down the drain goes right back into your drinking water. Thanks.

Michael Walters
novice - Water Gap, Pennsylvania


July , 2007

A. Hi, Michael. "Potmetal" may be zinc diecastings or aluminum diecastings (they look just about identical although aluminum is much lighter). But a 1968 car probably used zinc diecastings rather than aluminum, so zincating probably isn't necessary.

It isn't easy to fix those pits because the porosity absorbs water and plating solutions, thus causing contamination; plus the absorbed water or gases can come back as steam when the parts are heated and that causes holes and blisters. But the usual way to deal with mildly pitted diecastings for restoration is to copper plate them in cyanide copper plating solution and "mush buff"; this means basically to "mush" the soft copper plating into the pits by/while buffing. After the pits are pretty much filled with copper you can go on to more copper plating, then nickel plating, then chrome plating. Severely pitted castings require a plating artist to hand-drill & hand-fill every one, and will cost hundreds of dollars each. Moderately pitted in your eyes may be mildly or severely pitted in someone else's:-)

Good luck!

Q. Could I electroplate with a AAA (1.5 volts)?

Joe Wilson
hobbyist - Virginia Beach, Virginia


2007

A. For the purposes of a grammar school or early high school science project, yes you certainly can, Joe! Please see our FAQ: "How Electroplating Works".

For practical electroplating we'd need details of what you hope to do, though. Look into Faraday's Law because plating is energy intensive and that AAA battery is only going to be able to electroplate a very thin layer of metal on an item the size of a quarter before it's exhausted.

To understand this, simply recognize that a battery and a plating cell are actually the same thing -- but in electroplating we use a bigger battery or power supply to overpower the battery formed by the plating cell and force it to run in reverse. Your AAA battery doesn't move a lot of metal within it, so it can't move much metal outside of it.

Q. I have no experience with plating, but I have a great deal of experience with OSHA and EPA. The thing that would scare me the most about plating in my garage and disposing of the hazardous waste is this. Even if I did all the paperwork it requires to order, store and use the materials, then to dispose of the materials as hazardous waste, the thing that would not let me sleep another night I lived is the "Cradle to Grave" rule by EPA. Once you dispose of the material, the paperwork has to be maintained forever! And should the container you dispose of this material in should leak, then you the disposer are responsible and legally liable. The cost of a cleanup could be millions, and the fine is $25K per day until it is cleaned up. And you have to pay to reseal the junk, restore the junk and that means everyone else's junk stored with it. I just want to know, since I am just starting, what a fair price to pay for plating. I am restoring an old car and I want to plate the bumpers, etc. What would be a fair price?

Gus Weaver
hobbyist - Harrodsburg, Kentucky


2007

A. Hi, Gus. The biggest cost of plating, especially replating old stuff, is labor. It would be fair for a plating shop to charge you about the same amount for their time as a plumber or mechanic would -- maybe just a little more because of the cost of material and because a plating shop's equipment costs more than a plumber's equipment.

So the real issue is how long will it take, and this will depend on the condition (how much buffing and polishing is required) and on how high quality the job is. Reworking a single old bumper involves far more labor than manufacturing from scratch a new mass-produced one. So, unfortunately, it will cost at least the same as a new bumper; and replating an old diecast hood ornament can easily cost a hundred times the cost of a new one.

A. Ted is on the money with everything he has said. I began looking around for a home based chrome plating kit...thinking it was that easy. It costs about $500 here to strip, repair and rechrome a vehicle bumper. In my wisdom, I thought I could do it for next to nothing. I came up against ALL the hurdles Ted has mentioned. I paid the $500 and have a fantastic bumper and no headaches. I am impressed with your site and knowledge Ted...keep up the good work mate....Peter

thumbs up signThank you the kind words, Peter!

A quick aside -- some people just love working on their boats; they are happy as clams, beer can in one hand, scraper in the other, day after day. I'll ask on boating forums where I can get something done, and these folks will not tell me where to get it done, instead they bend my ear that I should do it myself. They cannot comprehend that some of us scrape our boat only out of necessity, that we hate this maintenance, and that our only interest is in getting it over with.

I think that part of the "friction" here is that someone will say they're trying to electroplate something and I may read into it that they just want the darn thing plated, and aren't familiar with the fact that plating jobshops are readily available to do it for them. Meanwhile the enthusiasts who enjoy hobby plating are convinced that the person would love to electroplate it themselves and we are stomping on their joy :-)

I especially appreciate your posting because it implies that you didn't particularly like the idea of electroplating yourself, and you tried it only to save money or because you didn't know that plating jobshops could do it for you.

April 8, 2008 -- this entry appended to this thread by editor in lieu of spawning a duplicative thread

Q. I would like information on how one would go about starting a chrome plating business on a small scale.
Any information would be helpful.

Maynard D.Tuttle
- Cherryvale, Kansas


April 9, 2008

A. Hi, Maynard. I think you'll find our previously mentioned Introduction to Chrome Plating will give you a quick but good feel for what the chrome plating business is about.

To open a restaurant without ever having worked a day in one would be a risky proposition, but at least you've spent thousands of hours in hundreds or thousands of restaurants in your life, so you have acquired some good info about how they run and what's important. You don't have that advantage when it comes to plating shops though. So I would strongly urge people to try to work a summer in a plating shop before volunteering to be eternally responsible for the toxic chemicals you will need to buy.

If that isn't possible, then at least join the National Association for Surface Finishing (nasf.org) and attend the local monthly meetings and the annual Sur/Fin convention, take a 2 to 4-day introduction to plating through NASF or Kushner Electroplating School, read a few of the most important books, and subscribe to the monthly journals to understand what's going on. Good luck!

Chrome-look paint

sidebar August 10, 2008

thumbs up signHi I can give you a good answer to this. I purchased some paint called Mirrorchrome from ALSA Paints. I have never in my life seen a chrome paint that actually shines like chrome until now. It took me several tries but finally after the fifth one I figured it out.

You prep your item just as you would for any paint job then spray on a Black gloss, I used an over-the-counter Base clear black. Clear coat it, then comes the tough part, wet sand it all the way to 4000 grit then polish it to a mirror shine then just spray on the chrome it takes about 15-20 min to flash over then polish it with a lint free cloth then let it cure for an hour then spray a coat of the clear over it. I did find you have to use a base clear clearcoat all others put a haze over the chrome. Anyway check out Alsa and see their videos; it does work.

Hi, Scott. There are many suppliers of "chrome-look paint" and we generally try to discuss things in generic terms here rather than bringing specific company names into it (why?)

But chrome-look paint is, for the amateur, a great alternative to real chrome plating. We thank you for providing so much detail on what worked for you!
