Zinc for electrodes:
Zinc sheet 5.5in x 5.5in x .0078in = .21 sq ft. (140mm x 140mm x .2mm) amzn.to/2FWoNOE
Zinc Strip 2.625in x 50ft x .0078in = 131sq ft. amzn.to/2JdUPvV More expensive but a roll lasts a really long time.
Epsom salt: amzn.to/2DUmZ7E
10 amp 30 volt power supply: amzn.to/2INtwVf
Go here to see how I clear chromate: • Zinc Plating a Steel H...
This is how I zinc plate steel parts with cheap, readily available ingredients. Yellow chromate, and clear chromate, which aren't expensive either, can be purchased from a hobby plating site, like Caswell Plating. www.caswellplating.com/ Zinc plating is a very durable layer of protection for your steel bolts, screws, nuts, and other parts. This plating technique is particularly useful because it doesn't require any exotic chemicals or expensive power sources. All you really need is zinc metal easy to source from hardware store, amazon, or ebay, along with white vinegar, epsom salts, and two D cell batteries. Zinc can also be derived from modern US pennies, which I will show in another video. The only thing you will have to buy special is either clear/blue chromate solution, or yellow chromate solution.
Your ratio is correct, but here is recipe.
1 Liter 5% white vinegar
100 grams epsom salt
120 grams sugar (makes it taste better) optional
8-10 sq in. pieces of zinc; Qty 2
1 amp per 10-15 sq in @ approx 1.5-4 volts
zinc plate positive & part negative
2 10 minute sessions with brushing or very light bead blasting in between.
Scale these ratios as needed. The sugar is suppose to reduce zinc grain growth to act as a brightener but I haven't noticed that it has any effect, so I just omit it now. Maybe it will work for you.
Another recipe:
128 grams epsom salts
43 grams zinc sulfate
85 ml 5% acidity white vinegar
27 grams sugar
1915 ml distilled or Reverse osmosis deionized water
8-10 sq in zinc plates: Qty 2
6 volts & 1.6 amps per 10-15 sq in
2 15 minute sessions with brushing between plates

Do you measure by taste or should I use 1g of epsom salt per 10ml vinegar?
Your ratio is correct, but here is recipe.

100 grams epsom salt
120 grams sugar (makes it taste better) optional

Thank you for the useful information!! Your videos are great.
Thanks:)

by taste. that's funny
Best, most effective tutorial I've seen. I was struggling with other peoples methods and this saved me, literally, lol. Cheers from 5 years in the future.👍
This is one of the most effective presentation I have ever seen. Well done and a million thanks.pls never loose your qualities of an Instructor and a person of good will.Asress
Thank you!
Agreed. Very informative and well done. Always wanted to learn how to do this. And it was entertaining as well. Going to give this a try next weekend. Thank you so much!
That was an excellent video, everything was well explained and obviously you understood the process as thoroughly as need be for the do it yourselfer Thanks a lot for posting it and to be honest I didn't think there was any way you were going to drink that spoon full of vinegar. I remember giving my daughter some for medicinal purposes and she had the same reaction, then I tried it and I realized it was Apple cider vinegar I was supposed to be using. She reminds me of that still 30 years later. Keep up the good work
Thanks so much :)
Thank you,! Thorough, clear. Have experimented with silver plating and will enjoy this zinc process .
Thanks for your comments :)
A master chef always samples the sauce!
Nice video. Very instructive. Thanks for taking the time and present it to everyone interested.
Thank you. I'm glad you liked it.
Nice video Arnold! Congratulations!
Thanks!)
Excellent demonstration of plating with zinc and chromating the surface.
Thanks
@@ArnoldsDesigncan you yellow chromate over valve covers that are already chromed or need to strip chrome off first?
Dude, you're getting a subscribe for that spoonful.
Thanks! I just saw your comment.
❌🚨❌ URGENT PROBLEM!!!
Dude... That Spoonfull Deserved 2x , So I Gave You *TWO* “THUMBS UP CLICKS”.
BUT.... I have a sneaking suspicion that DOMINION and/or THE DEMONCRATS are running the VOTE COUNTING.
BECAUSE -->> The FIRST click gave you an increase of ONE “+”, then the second click LOWERED IT BY ONE !!

Totally worth it!🤘🏼
You earned it!
Thanks
Gee Arnold, I don't recall you putting a gun to any critic's head to make them watch your enjoyable videos. I am now a subscriber because of your quick witted responses to the jerkwads and your ease of delivery of information. Thank you kindly
Thank you for your comments. I think some people just don't like anything, themselves included.
Totally earned that thumbs up.
Thanks :)
Thank you so much for this video!
The taste test was awesome
I thumbs upped your video because you actually did it.
Thanks
That was epic you tasting the solution. It was also old school afford for getting likes. Well you well earned every like
Good info, thanks. Video is more tolerable to watch at 1.25X or 1.50X speed though. BTW, if you connect the power supply to the zinc plates in the beginning, you'll prime the solution a lot faster.
3 minutes of information compressed into a 30 minute video.
How kind of you to show the gratitude and appreciation so much needed in today's world. I hope we did not keep you from your study of curmudgeonry
agreed

TH-cam limits me to 2x playback speed 😂
@@MafiZed the sarcasm went right over your head
Omg…that was a good belly laugh when you sampled the solution. 😂
Heck yea!, You got a thumbs up and a subscribe!, Thats so me!, I was experimenting with rust removal last night and just had to try a sip of the ascorbic acid solution. Your my "Brother from another mother"!
Yep, ascorbic acid is nasty tasting too, but good for you. Thanks for the sub! :)
You guys, I poured out my citric bath today, after the 50kg of parts that went through, I’d assume it was swimming in cromates
Gave a like for that drinking of the solution lol👍🏼😂
Thanks!
Yeah made my day. Thanks op
Holy moly man get to it
Great video. Thanks!
Thanks :)
Magnificent information that could have been told in about five minutes.
I was feeling generous that day.
Hell of a way to get a thumbs up but you got it
thanks for sharing I'll have to try this out. Jay
you earned the thumbs up
Thanks :)
A simple improvement is just a make a round anode that goes all around tank, and hence around the part to be plated. If you have a strange shape - for example a bowl - then you can add another little anode in the middle of the bowl to ensure that it's plated too. (Source: That's what we used to do when silver plating big spoons and ladles).
Also, for best results suspend the part vertically between the anodes...
Finally, better NOT to use steel wool to clean; particles of iron will remain in the soft zinc and accelerate corrosion...
Lol. When you drank the liquid. 😂😂you were talking funny after that. 😂😂👍
Magnifique !!! Merci !!! Thank you
Thanks!
Good video buddy thanks you
Thanks man.
Great video! Thank you for sharing this! Could you make some more video showing the process on some other items to show how it turns out? Do you have any learned improvements you can share?
I'll give you a Thumbs up just for the laugh. Great clip
Thanks. It tasted really bad.
A thumb's up for that spoon full.
Reminded me of this th-cam.com/video/pwHr88gFhBQ/w-d-xo.html
I appreciate your helpful videos (and don't understand why my comments seem to disappear), but just in case... If I plate a complex part with some angles and areas that aren't easily accessible to steel wool, is there some other way to ensure I can do several plate steps to get a good thick consistent layer? It's for a fuel pump hanger, and I don't want any risk of rust. Thanks again for the really cool and educational videos.
Thanks. You could probably bead blast between layers, or maybe just one thick layer would work.
you mic the chromate with what?
with water or battery water?
Brother Arnold,
Great movie!
Thumbs up for the movie, wish there was a 2nd thumbs up for your choice in tablespoon beverage.
Loved the vid and I am exactly at this stage myself! My own results are spoilt by brackets and fixings that don't match the quality Of the rest of the vapourblasting and rust before the customer collects. Worse still the blasting takes off the yellow passivated finish so you never get that original look back even if the zinc plating is still good....
Thanks, Paul. In my next video about zinc plating, which is a continuation of this one, I will be zinc plating a handle using clear/blue chromate. I explain how I use vapor blasting to make the zinc finish more closely replicate the cadmium look. If you lightly and quickly vapor blast(or bead blast) the raw zinc, and then apply the yellow chromate, it will closely match what you are looking for.
You are a brave man. I stopped tasting solutions in grade 7 when I accidentally tasted a sodium hydroxide solution and was only able to eat jello for a month and a half. It was not fun. I wasn't being stupid there was also a supersaturated salt solution we were supposed to taste. I mistakenly thought that the teacher had warmed the salt solution to help dissolve the salt. I didn't yet know the reaction of sodium hydroxide and water. A case of thinking I knew everything followed by a hard dose of reality. :-(
Great info though. I will put it to good use.
Thanks for your comments. I don't taste all solutions.
I honestly didn't think you did, it was just that watching you do that just gave me a flashback to nearly 50 years ago. I hadn't thought of that incident for a long time. You have some really good vids glad I found your page.
No, I know. I'm glad you like my channel.
Great video as always! Is there anyway we could get a quick video of your vaporblasting setup?
Thanks! Yeah, I can do that. I have a video up already about my filtration system I built, but it doesn't cover the whole vapor blasting cabinet.
Was well worth a thumbs up! ... I'm not going to drink it though! lol ... Thanks for sharing ;-)
Thanks!
My home building boat expert told me Zinc Nickel Chromate plating is even more durable. Maybe just a different chemical or metal anode or extra step. Worth looking into...
Nickel over zinc sounds more durable, but I honestly don't know anything about plating nickel. I know copper and nickel is very durable. I have some nickel acetate laying around here for sealing anodizing dye. I could try that. What's the worst that could happen? If you hear a faint explosion due north, you'll know things didn't go well.
You ever give this a try
Thanks for shareing
In an effort to standardize on units and to make the method of measure based on common household kitchen measuring devices, at least here in the USA, I offer the following:
1 liter = 34oz and that is 4.2 cups
100 grams = 3.5oz = 2.5 tablespoons (@ 2.66 g/cc density for epsom salts)
120 grams = 4.2oz = 5 tablespoons (@1.59 g/cc density for table sugar)
Most folks may not have a gram scale handy.
Thank you for the conversions :)
Thanks for your reply mentioning vapor blasting, but I have no access to that. Seems like normal glass beading would be my option, worked well to clean it so maybe if I try and do it just enough to change the finish between plates.
That will work. Just make sure the beads are clean.
Once a chromated part has hardened, have you ever tried spray a clear on it? Automotive clears are two part and hard once cured, sticks to everything but certain results of can on clearcoat can has darkened the color. So under a vehicle is a harsh environment. Working on imports since the late 60’s, but at dealerships in the 70’s, boy, they sure love their chromate, yellow-zink, What every you want to call it, but ever but, bolts, latch, cap, cover, pulleys, etc. I still own a 1969 Datsun 1600 Roadster. It’s a two door convertible with a ful peremeter box frame. No flexing there. If use placed an MG “B” or Midget onto a normal hoist and left the ticket on the seat, you can’t open the doors. New! That is if they would start and run off the transport. The driver had jumper cables, two short chains and electric winch to get them on the semi & off in a controlled manor. We had so many none-running new vehicles, the service manager purchased an electric car pusher that a first glance, looked like a snow thrower. It made by the twin cities to this day in 2021. This was 1977. The next year I took 8 test, 60 questions each and passed all. I became an ASE Master Tech in 1978. Re-cert test were 40 questions but after five year or so.
So nice & clean, polished, zink plated and dipped until color was matched.
You know, you can take a 2” wide mild steel strip, place a scratch mark at 1”, dip to mark at 4 seconds, deeper to second mark another 4 seconds and stop at the top. Now, depending on how deep your bucket is, but divide into 4 or 5 segments, with the bottom the darkest and so forth. That way you can create a gauge to show the color choices if you’re buddy wanted to slip some pocket change your way for his parts. I have rebuilt hundreds of carburetors over the years, from Q-Jet 4bbl, Ford 7200/7400VV, to side draft soled, Muniki, and even carbs the said could not be fixed. The dealer parts had paper books & the top half w/choke was circled and indicated as part #1. Dodge Colt, D50 pickups, Omni’s all had Coolant to sealed housing with a wax inside. It expanded with great force against a piston that pushed a rod, that unloaded tension off a heavy gear, then a spring allow the choke to open. The screw below that wax, had a jam nut sealed with red epoxy. Chipped epoxy off and backed off jam nut, run the screw in. The wax over time would shrink. Choke never did open. But work on EFI injectors in 1977 on the 280Z. The other two would not touch them. It and the Cadillac Seville w/5.7L where they only two with an electric injector in each cylinder. Not to be confirm with Rochester mechanical or Bausch CIS air-plate system.
The 280Z was an in-line 6, but had 7 injectors. The injector #7 sprayed only with temperature. It acted as choke and ran off a single thermo-time switch. Stamped on the side was time/temp max. Still have a metal box with that stuff in it. Right next to metal chrome tach/dwell meter and 7 distributor wrenches. I must be old. Nope, just seasoned.
Lol at 12:55 🤣 good effort man
Do you have a video explanation up on the yellow chromium solution stuff. I wanna see how it's made or where you get it? To see if it's good to do all this on some gun parts as a hobby project in the future.
Caswell plating products
if you were to be seen in a British yorkshire village you would not look out of place!! edit 13 mins you earned that like
FYI go on eBay find a chunk of zinc I think I paid $7 for a big Ingot of it 99.8% pure zinc metal and fill up a beaker of water break off a chunk set it in there and drizzle a little bit of sulfuric acid in there until it starts bubbling. Apply little heat when it slows down bubbling or a little more sulfuric acid wait till the metal is gone filter through a coffee filter cook it down by half
I probably have three quarters of a pound of zinc crystals just from doing that overnight last night
I assume that makes zinc sulfate? I had some fun with that a while back. I partly filled a water bottle with battery acid, dropped some zinc inside, and put a balloon on top. It fills with hydrogen pretty quickly.
Arnold, how long do you typically need to keep small hardware in the solution? How long do D batteries typically last?
Great video thanks. I'm going to give your method a go, as it is so much cheaper to start out, with just a bit more finishing work to get good results. Cheers.
Thanks. I'm glad you found it helpful.
Bro, you are my Hero! You drank the electrolyte!!! That is a sign of a True Alchemist! Major Props from a Humble Metallurgist!
Would you ever need more than 5amps to do this? I’m looking at buying a 60v 5a unit or a 30v 10a model
I'm going to try this process with my fuel pump hanger, obviously larger so I will try a five gallon bucket. I'd like to do the chromate solution, but not sure if the amount I need for my one part will be cost effective. Can you brush the chromate solution on and rinse it off instead of dipping? Thanks again for the great videos.
Hey that's been my wish as well!... I really dislike the corrosion that attacks the top exterior and even interior of sending units. I actually created a bath on the top of a tank just to plate the exterior of a sending unit and a narrow margin around the sending unit (90 camry). Trimmed and taped cardboard around the tank contours and sealed and caulked the inner side of cardboard with Geocel caulk and brushable sealer. The bath set up worked great (didn't leak a drop even with the rust cleaning solution (muriatic acid) inside! However the zinc plating I was attempting didn't cover evenly. The un eveness ruined the gaines.. Some areas plated thick and others stayed bare. Bare spots would rust immediately.. I was bummed. I hope to learn what mistakes I made and try a similar better attempt on a tank some time in the near future.
You didn't go into the zinc chromate solution . How much is it per gallon and where do you get it ?
Have you done this process on magnesium parts ? You showed some refinished Mercedes valve covers . I know a lot of Mercedes models have use magnesium valve covers.
A bit late to the party, but thank you for the education! I also added the same amount of sugar as Epsom salt as I was told this would enhance the finish. QUESTION: Is it safe to keep the solution - I have removed the zinc for now - in a sealed plastic container for future use?
Thanks. Yes, I store the solution for months in a plastic bucket with lid. It doesn't seem to hurt it. I just wash off the zinc strips for later.
Thank you for the quick reply!
Enjoyed your video on plating. Where do you purchase the yellow, blue and black chromate?
caswellplating.com/
Does the salt solution not cause immediate corrosion of the metal?
Just wondering if we are burying brand new rust under the zinc.
Thanks for posting, very nice breakdown. I was wondering if you could help me with an issue I'm having. The threads, the edge around the flanged hex head as well as the edges between the flats of the hex head have good coverage but the flats of the hex head, the flat part under the flange and the shank have little to no coverage. I've tried playing with the amperage, periodically rotating the bolt in the solution and using an aerator but still having same issue. Any ideas would be greatly appreciated, Thanks!
Thanks for your comments. I haven't had this happen, but sometimes I've gotten shadowing. This is where a part doesn't have line of sight to the zinc electrode because of another surface obstructing it. You might want to try facing the underside of the bolt head toward the zinc and see what happens. You also might want to adjust your voltage a little.
Thanks
🤣That was to funny!
What happens to the magnesium in the epsom salt? Does it stay in solution because of its different electro negativity?
Epsom salts makes a great laxative!
Yes it does.
Hello for the battery you can use a cell phone wall charger I am using a play station wall adapter :-) :-) great video and for asshats haters are going to hate
Thanks for your comments!
Cool. So what you're saying is to get the chromate solution after zinc plating it?
You could. I would chromate it as soon as possible though.
Would stainless wool or even copper wool contaminate less than normal steel wool? I'm about to do the process and want to be sure the zinc adheres strongly. I also got the chromate chemical for when the plating is done. Can't wait to see how it comes out.
I've never had an issue with regular steel wool. The stainless wool I have is really crumbly, so I don't use it much.
thanks sir
👍
That was worth the thumbs up 😂😂
You mention dipping the part in the acid before plating, to get a better bite. Doesn't putting them into the vinegar solution for plating do the same thing?
HCI is what they call for. It's much faster.
what if you get the goblin icing and you applied some light strong light or lasers to the solution or maybe encased it in like a dark room or something it would be interesting to see what the product will look like kind of different instead of just regular I think.
Hi Arnold. I finally got the zinc plating to work. When I dipped the part in the yellow chromate it's dull looking. I used muratic acid. Could you help me
i did see the red probe connection?have you made it in contact to the zinc foil or not?or the negative (black probe )seen that it was connected to the one point of the rod.
Red positive is connected to the zinc foil. The part is connected to black negative.
One more question: your power controller looks pretty expensive. What is out there above the D cell batteries but not too expensive?
If you can, get a dc regulated power supply. They can be had reasonably on amazon. The one I link to is on sale for $59. It will make your life easier, especially starting out. Eliminates one variable of failure.
were do you buy the chromate solution you dip the part in at the end
Nothing like trying out yiur own product.. Quality control and all that!! 🤣
Will your power supply go down into milliamps and millivolts?
Is the 10amp power supply necessary? I'd purchase through your amazon affiliate link, but after clicking, I just found the 5amp version of the same power supply on Amazon. Based on your instructions: "1 amp per 10-15 sq in @ approx 1.5-4 volts" it sounds like a 5amp power supply would be sufficient.
For small parts you wouldn't need 10 amps. I linked to it because it's the one I have that I like. Now that you mentioned the discrepancy, I will change the affillite link. Thank you.
Thumbs up!!
Hi I made a copper plating solution with soda bicarbonate and distilled water and made my copper sulphate with the anode and Cathode hooked up to a dc to dc buck converter with an 18 volt Dewalt cordless battery. I kept my voltage at 3 to 5 volts while stirring every few minutes. When I was plating my cheap feeler gauge after I cleaned the feeler gauge of course using soapy water, rinse then electronics contact cleaner. I failed so I used prepwash to wipe on and off.it worked great on the feeler gauge. But I tried doing a kitchen spoon and no matter how much I cleaned the spoon it was blotchy after polishing to a shine. I c a nt buy Muriatic acid in Australia. Can I use hydrochloric acid? The air bubbled is a great idea. I will definitely do that. Any reply appreciated. Subbed and liked!🙂👍👍👍
Nice
Thanks
I really like the video -room for improvement is to use rubber gloves and eye glasses when dealing with these chemicals.
Hi Arnold, I have to ask is there a cheap place to get yellow chromate from? as the only place I can find it is caswell and they want $50cdn for a 4 oz bottle of it. I am trying to do this on the cheap as well. I want to protect my brake rotors from rusting up. I have most everything I need around like the power supply and zinc but as the costs go up I start the debate in my head why don't I just buy coated rotors
I get mine from Caswell. It's expensive, but lasts a long pretty much forever. Keep the clear/blue chromate in a glass jug though, and cover it with aluminum foil, or keep in dark storage.
So if I want to do something larger do I just double the amount of everything?
Yes, you can scale it up.
Hi, Great video. step by step, love it. where can I get the liquid is in the 3 gallon bucket Yellow Chromate Conversion solution. Thanks,
Thanks. The liquid is yellow chromate solution. You can get it online at www.caswellplating.com/ if in the U.S. They also have an online store in Europe, but I don't know the web address.
Hi , Thank you - Can i use Cooking /Nomal vinegar ?
I can't believe U drunk table spoon 🤣
Arnold's design ive just got a power supply similar to the one you have its a 1503DD model it puts out 15v 3A but the problem is that iam not getting good results by useing this i dont get it that i was just useing a 12v 3a bike battery & was getting brilliant results from that with the spring to reduce the power but the spring keeps burning out so that's why i bought this rectifier thing 1503DD 15v 3A but it just says error on the amp side & just keeps bleeping have i bought for wrong one or something it never says nothing about useing it for zinc plating in the description it just says for mobile phone repair have you got any ideas about this buddy
I have an automotive battery charger that can be set for 6 or 12 volts and 2 or 10 amps. Could I use the 6 volt 2 amp setting for the power supply? It's more power than the 2 D-cell batteries mentioned in the video, but it is about the same as the power supply mentioned in the second recipe shown in the above description.
You could try it. I would probably stick to 2 to 4 volts though. I think beyond that you're going to get poor adhesion. The slower the plate, the better the adhesion. Plus, the battery charger is going to regulate amperage based on load, so you won't have control over that. You could use light bulbs in series to control it, but it is a pain.
Must of nodded off ,did I miss much ?
One hell of a lot apparently !
Have you ever measured how much your putting on the part like 1 2 or 3 thousand of an inch also in a certain amount of time say 1 thou at thirty minutes really enjoy your video
Thanks. I measured a while back but don't recall now. I don't think it amounted to much at all. I will next time I plate.
lol thumbs up for drinking it.👍
Thanks!
one more question, is there supposed to be a good temp for this, im doing it in my garage in winter and its cold? is there a temp i have to shoot?
I don't know if temperature changes anything. I usually plate at room temp.
Can you use this with Magnesium engine parts instead of Steel?
even though this video is a bit old, I have some insight/questions that someone here may know an answer to.
If I'm trying to process a batch of 50 m6x10 fasteners, let's say, hanging each one on copper wire would be excruciatingly time consuming. Since we need the conductivity, can I use a wire-mesh basket, put negative lead on it (obviously), and poke the fasteners through(i.e., only hanging from the bottom of the hex head), and then do a second plating after each fastener has been turned upside down to ensure contact of the bottom of the head?
This way, you could do multiple fasteners at once and all it takes is putting them in the basket and flipping them once.
I must keep missing what is in the white bucket of chromate & how is it made.
You wear a flat cap and drink strange things, but it's a funny accent for a Yorkshire man. Thumbs up from me.
Lol
