HOW TO SET-UP A SIMPLE HOME ELECTROPLATING SYSTEM.

-

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!

A. Our FAQs "How Electroplating Works" and "Introduction to Chrome Plating" may help you, Raymond -- please give them a look. But unfortunately it may not prove practical for you due to OSHA safety regulations and EPA waste disposal regulations, especially if you want to make a business out of it.

The plating industry was the country's very first EPA regulated industry, and the burden of compliance is heavy even for full time businesses. 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, suddenly 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 its disposal. Best of luck!

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. PRK,

Yes, you saw plating kits for $25 some time ago -- today it's around $75 =>


... but these were/are 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 like the site's supporting advertisers GoldTouch, LDC, or Sifco. 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 regs before you buy chemicals, especially chrome. Good luck!

Q. Raymond J of Holyoke asked about a home plating system. Did any one answer him ? If so what is the answer? I want to chrome plate my auto parts and will be 6' L x18" W

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 much much smaller and with a chrome-free plating solution.

Donald, I don't think JC Whitney offers one anymore but, as noted, there is an under $75 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 system. We're certainly not trying to talk you out of a $75 investment in learning. 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 and figure out how many 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 match, etc. It's a big job.

Our concern isn't whether you spend $75 -- please do! Or please try the plating experiments in our FAQ "How Plating Works". 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!

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.

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, Mil and ASTM plating standards, addresses of free plating libraries, and tens of thousands of highly detailed responses to plating questions and problems.

Tyrone: This isn't the Hotel California; you can leave any time you like. But you, too, are welcome to tell people how to do electroplating at home. We'll give you all the space you want 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 a great one, thanks! 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 or even 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 get away with driving without a license, registration, or insurance. And in my experience as well as your own, you can probably illegally operate a small plating business and stay below the radar. And many of the regulations do not apply if you never sell a plated product or your plating service. But if a neighbor child contracts cancer for any of a thousand natural reasons, and her parents find out that you were chrome plating in your garage, as a business or even a hobby, God help you; your life as you knew it is over.

thumbsup2Chrome 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!

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 significantly 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. Good luck!

+++++++

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". Beyond that 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 layer of barely visible thickness on an item the size of a quarter before it's exhausted.

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


+++++++

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.

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

Thank 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 almost cannot comprehend that some of us scrape our boat only out of necessity, that we despise this maintenance, and that our only interest is in getting it over with.

I think that part of the "friction" here is this: 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 absolutely love to electroplate it themselves and we are stomping on their potential 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.

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

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 Plating School, read a few of the most important books, and subscribe to the monthly journals to understand what's going on. Good luck!

thumbsup2Hi 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. We try to discuss things in generic terms here rather than bringing specific company names into it because, with the anonymity of the internet, there is often a race to the bottom when salespeople see other brands praised, so they pretend to be satisfied customers.

Q. Can I do some Chrome and Brass plating at home?

I am restoring a 43 ft. 1958 boat. Lots of bright work to cleaned up and some of the parts are hard or impossible to replace. I have sent some things out for professional plating, but the cost can be daunting. I am a chemical engineer, so I appreciate the environmental and other operating costs of the professional shops. I was just wondering if there are any replating kits and instructions that I might use safely at home to do some of the small plating work. Thanks for you help.

A. Hi, Bill. As you can see, we appended your letter to a similar thread, rather than starting over and risking no replies due to reader fatigue with this issue. We have an "Introduction to Chrome Plating" on line here that will help you understand what is involved. I could not suggest real chrome plating at home because it requires toxic and carcinogenic hexavalent chromium, but there are imitations available. The best brass plating is cyanide based, which is an extremely powerful poison, but you may be able to find a non-cyanide brass plating solution (from EPI or Zinex, for example, or a hobby plating site) that is good enough.

Hi my name is matt, I am very much into building cars and motorcycles and just about anything custom. I have never had anything plated and I understand the prices can be pretty high, I am just wondering if there is any type of metal plating I can do at home in my garage for my self, I actually have a set of wheels that are hard to find and would like to try to plate my self, (the chrome is peeling on them) I would also like to plate a lot of other parts under the hood of the Camaro I am building, it's a 1979 Z28 and I am trying to completely restore it, and there is a lot of things I would love to chrome plate and don't want it to cost me a arm and a leg. I don't mind to labor at all I found a kit for 899.00, this is close to the kit I found, the difference is the kit I found is 6 gallon instead of 4.5, I would like to know also how much plating will a 6 gallon kit make and do you have to have any kind of license or permit to buy the kit. I understand it is an art but I do like learning and would really love to learn the trade without spending over a 1000.00 dollars, I would also like to know if there is any kind of newer technology that would make it safer and easier for someone with no experience and the finish I am looking for with the automotive parts. I have always been a quick learner and believe I can do it. There are also a lot of books that say how easy it is to do it at home and I don't believe that and am kind of sketchy about them. Any help would be greatly appreciated, thanks matt. P.S.: this is the kit I found, like I said it's exactly the same except bigger 6 gallon not 4.5 Gallon Kit

Q. Greetings Ted.
Looks like a great forum with lots of information.
I apologize for not reading all 50,000 pages, but I just want to permanently solve a corrosion problem in a farm tractor. Two small parts, critical to the operation of the diesel fuel injection & control system in the C.A.V. fuel pump repeatedly corrode & seize, requiring the disassembly, cleaning & polishing, and then reassembly of the C.A.V. pump. Very tedious and time consuming, great opportunity to lose parts when done in the field, etc.
Both of the affected critical parts would fit in a coffee cup at the same time, and, since they rust, appear to be ferrous metal.
After reading the basic tutorial, it appears it would be simple to zinc plate these parts in the farm shop.
Would it be faster to use battery acid electrolyte as the liquid (instead of vinegar)? or dissolve a zinc anode in the electrolyte, then "dip & wait"? (as mentioned in "solution disposal")?
What would the effect be of raising the current source from a flashlight battery to a 12 volt vehicle battery?
I realize that that depositing material (zinc, copper, chrome, or other) will cause the parts to be a different size afterwards, and I will have to get it back to the correct size in the critical area, either by pre polishing (we've already polished it a lot!) or post polishing.
We don't care what it looks like; I would like not to have to ever see it again, but until we solve the corrosion issue, this machine has way too much unplanned maintenance.
Obviously, to remove the corrosive from the fuel would be step #1. Apparently that hasn't happened so I am looking for additional things to solve the problem without spending large sums of money, preferably things I can do with materials on hand.

#2, "new" parts installed in this equipment also corrode as fast as the old parts.
I understand this process is probably hazardous, I am aware of safety issues, and would like to avoid problems by being aware of them, and being prepared.
Thanks for any advice & assistance you can share.

A. Hi, Chris. Don't apologize for not doing the impossible -- there are threads here that I haven't read in 10 years.

Yes, battery acid is a stronger and better electrolyte than vinegar. And for small scale amateur attempts like this, zinc boat anodes should work as the source of zinc. You will find that 12 volts is way too much though. The zinc ions won't be able to transfer electrons fast enough, so water in the solution will be converted to hydrogen gas, and the parts will "burn" instead of getting good plating. Maybe try rechargeable batteries. A battery pack and charger from an old cordless phone would probably deliver 2.4v or 3.6v that you could perhaps try. Or you could try the under $75 Eastwood system mentioned above. Good luck. But consider having a machine shop make stainless steel replacement parts?

Q. Uh, I don't have a dog in this fight, but I AM curious about a similar process that I have used to remove rust, paint and old finish from motorcycle parts. I use a soap solution, and a AC/DC 12V source. The crap comes off over night and leaves a truly workable surface for painting.

I'm wondering if, should I simply reverse the poles of the DC source----assuming that I have prepped the selected item well enough--- and provided some source of material such as junk silver jewelry for a silver finish, could there be a reasonable plating outcome? Thoughts?

Best Wishes,

A. Hi, Bruce.

There will certainly be an outcome: we have an FAQ that teaches 2nd and 3rd graders how to zinc or copper plate with kitchen-safe materials in minutes. In principle electroplating is very very easy. The hard part is obtaining truly useful plating -- plating that will adhere rather than brush right off or peel off; plating that is free of pits and porosity which accelerate corrosion rather than retard it; plating that will have a good shine to it and reasonable thickness. I think your prospects for plating with home brew are better for nickel plating than silver plating though. Good luck.

Q. Hi Ted,

I'm looking to increase my knowledge of the principles and practice of metal finishing, with a view to turning my brush-plating hobby into a more serious business venture. I've successfully plated several small objects and have had many people offer to pay me to plate objects for them, but here in the UK there appears to be a dearth of books/guides aimed at amateurs with an interest in the chemistry. I've already researched the criteria for, and costs involved in, setting up a small garage-based electroplating shop and have been given advice on handling, storage and disposal of hazardous/chemical waste. I now want to do some reading to increase my knowledge of the processes involved and I'm therefore looking to obtain guides from overseas, especially the US, which seems to be the place to get information - I therefore wondered if you could point me towards some decent literature which I could order from US...I'll even forgive you guys for spelling sulphur and aluminium wrong :)

I am an inventor and experimentor who would like some input into perhaps another method to plating involving DC energy of high voltage.
If you or someone you know has read of this, can you expand upon the process? Also, what is the optimum voltage and amperage for the electrowinning of Gold? Thanks in advance.
Daniel.

A. Hi Daniel. I've heard of Nikola Tesla and understand that he may have been an under-appreciated genius. However, every book I've seen about him seems wrapped in so much silly mysticism that I'm not going to read them :-)

Sorry, I don't know anything about plating involving high DC energy, although other readers are welcome to chime in.

A plating cell is the same thing as a battery being overcome and driven in the opposite direction. For example, a student's "lemon battery" with zinc and copper electrodes generates 1.2 Volts as the copper plates out onto the zinc. So to plate zinc onto copper will require somewhat more than 1.2 Volts to pump the electrons in the opposite direction. You can look up the "galvanic series" to see the natural electropotentials of each metal, and you'll see that gold is very noble. So the ideal voltage for electrowinning gold will be very low so that you don't plate out anything else that is in the solution.
