nickel plating question

Hi. There is instruction on this address https://www.instructables.com/id/High-Quality-and-safe-Nickel-Plating/ how to make high quality and safe nickel plating,and i have some question about that. When he showed to add salt to the vinegar in order to make the vinegar  more conductive,isnt the salt become Na and Cl ions? Will the Na positive ion stick to the negative nickel plate?(while making the nickel solution-step 3)? Will the Na positive ions stick to the item that we are plating besides the nickel( in the plating process-step 5)? will it spoil the object that we are plating with nickel? I see in the supermarket vinegar which said"synthetic vinegar" 5% acetic acid,water.(for food).Is it ok? when he said(step 4)"You can further clean your object by reverse electroplating (ie "electrocleaning") it for a few seconds.  Hook your object up to a negative voltage, a WIRE to the positive voltage, and drop them both in a vinegar salt solution for 10-30 seconds.  This will remove any left over oxidation" What wire did he mean? and the last one:how pure is the nickel should be?because i notice that most of the nickel sheet are about 99%-99.7% purity.is it ok? can i use pure nickel strip(97% pure nickel)that is used for battery welding? Thanks in advance.

electro cleaning before electroplating

Hi. I made the instructable of A_Steingrube"high quality and safe nickel plating" address:https://www.instructables.com/id/High-Quality-and-safe-Nickel-Plating/ and i want to be sure that i did the elctro-cleanning that is mention on step 4 correctly. I try to ask A_Steingrube through the comment place and the private message but i have not get any answer yet.so i try to ask here. I made the elctro cleaning while my object was connected to the positive voltage and the wire connected to the negative voltage.I did that ,because i understand that the object sould be dissolved abit and this should be happens on the anode(connected to the positive voltage) but in step 4 he mention to connect the object to the negative voltage in order to make the electrocleanning.SO,is there something that i miss here? Thanks in advance.

How to vary output of DC power supply?

I have a DC Power Supply, Model 20R, 120 input, 13.5 DC output, 20 amp.  Is there a way to change the output Amps?  I want to use this power supply for nickel plating. I need the amps to be variable or fixed at more than the onr setting of 20 amps.  (example 2, 4, 6, 8, 10 amps ) This is a nice heavy duty PS made in USA.  A new DC PS is over $400 and they are cheaply made imports. I used to repair electronics for NASA years ago.  I most likely would have known how to do this back then, but the older I get the more I can't recall. (Old age is not fun!!) My point is, I have the experience to do what you tell me to do. Thanks

NIckel Acetate Creation from Nickel II Oxide for Nickel Plating

Chemistry question here.  I wanted to play around with some nickel plating, and I started to follow a popular recipe that I saw on YouTube.  It started with Nickel II Oxide, placed in a malt vinegar for a week to create a solution of Nickel Acetate that you could then use as a bath to plate things with Nickel.  I purchased 100 grams of 99% grade Nickel II Oxide, and let it sit in 2L of vinegar for a long time.  After 2 weeks there's no hint of the emerald green Nickel Acetate.  So I purchased some glacial Acetic Acid, and added it to a liter of distilled water to make a 50% weight solution of Acetic Acid to make a stronger solution, and still a week later nothing green.  Solution is in a clean glass vessel.  A local chemist at work said it would be slow, but man, this is taking forever.  What am I doing wrong, or what could I do different? I know Ni Acetate can be achieved with pure nickel and electricity in vinegar, but I really want to try to convert the nickel oxide.

Copperplating with non-pure-copper?

Hi! I plan on some experiments with a modified method i saw here for PCB-plating with copper to make the holes conductive. Now the question: What if my metal is not 100% pure but has some impurities in it? Does it still only "transfer" the copper and leaves the impurities as slag behind? I think it should be this way, since a similar approach gets used in refining metals to a very high purity; but i am unsure... Lets say i do: Follow the basic recipe (with smaller ammounts!) @ http://www.thinktink.com/stack/volumes/voliii/consumbl/cplatmix.htm and use copper sulfide. I think the trick now is that only copper-ions get disolved in the copper sulfide and nothing else. Those ions become plated to the other pole and thus i get purest copper plated to it?

Plating Silver/gold (or any other hypoallergenic metals) on a Brass ring. (Without access to specialized chemicals)

Greetings fellow makers and crafters. First off I want to thank all who take the time reading this question. So, lets get started. A while ago I decided to test my crafting skills and made a beautiful brass ring out of some very old 20mm brass ammo casing. A nice repurpose in my opinion. The brass however oxidizes very quickly and stains my finger green. And it seems like the skin underneath is developing an allergic reaction. Either to the oxide stains, the zinc, or maybe some nickel contamination in the metal? It appears dry and reddish sometimes. Because I put a lot of effort into making the ring and don't want to discard it I finally decided to electroplate it. Plating it with copper would be quite easy as it seems that copper nitrate can be made with citric acid. It would however still oxidize and leave stains. My second thought was Nickel, but I discarded the idea because I seem to be allergic to other Nickel plated Jewelry. Now comes the hard part. I live in Bosnia and Herzegovina. A country where I can hardly come across any chemical supplies. Even simple things like activated charcoal or hydrogen peroxide are nowhere to find. I could silver plate the ring if I had access to nitric acid. But as you see that would require me to buy it from some online store which I really try to avoid. I could start making my own nitric acid with the use of the Birkeland Eyde process. But I'd rather have something more safe, health friendly and without the chance of getting roasted by a 10-20kV transformer. Anyway, back to the topic. I am currently out of ideas on how to approach this project. So I am asking you guys if you know of any of the shelf products which have the required chemical ingredients that I could utilize to make this project a success? Thanks again. ------ And Happy New Year! :)

How do I recover the silver from unexposed B/W photo paper?

I have several hundred unexposed sheets of B/W RC photo paper. I know I need to use a fixer and a cathode/anode set-up. What is a simple, easy-to-obtain or make fixer, and what voltage/amperage combination do I need? As I remove the silver from the fixer, can I reuse the fixer pretty much indefinitely? What do I use as electrodes? All help is appreciated.

Beginner Jewellery maker. Question about gold/silver plating

Hi there, I'm starting jewellery making as a complete beginner and want to use Metal Clays to do this as it seems one of the easier and cheaper ways to make jewellery at home. I looked into lost wax casting, but there are no studios or workshops near where I live to do this. I really love gold jewellery, and was wondering that if I used bronze, copper, or silver clay, am I able to plate it too? I've seen those electroplating kits online, but I was wondering if it would work after I've finished making my jewellery piece with the clay.  I've also seen videos about 'silver accenting' copper clay... Is this just basically like coloured base metal (costume jewellery), or is it real sterling silver (i.e high end costume jewellery). Any insight anyone can provide is very much appreciated! :) Erika

Is it possible to make your own electroplating solution?

Is it possible to make your own electroplating solution? Couldn't one simply toss some atomized copper dust from the sculpture supply store into a hydrochloric acid solution, and let it dissolve? If so, what other chemicals are necessary, and what approximate proportions should they be? I'm thinking quick and dirty here, specifically for electroforming medium sized objects. Thanks!

Suggestions for bonding PVC sheets to ABS sheets, for composite armor?

I have a crazy idea for making tough plates out of thermoplastics. Does anyone have any ideas for bonding PVC to ABS plastic? Two materials will add to the strength and durability of the plate. If possible I would also like to sandwich some kind of fibers in between the two plates, such as carbon fiber. Does anyone have any ideas on this? I was planning on heat forming the sheets, then maybe pressing them together at high heat, but an easier method would be appreciated.

How can i use silver from x ray films to eletroplate a soldering iron tip?

That's it: i have a ton of old/useless x-ray films and a bare copper iron tip. I usually clean the x ray films with sodium chloride (at 2%, from bleach) to use the pvc sheets to make stencils. Once i left the resulting solution to air dry. It took something like a week for the 25cc of liquid to evaporate and left some crusty, green matter - which, i'm pretty sure,had silver in it. The questions are: what is that solution? Can it be used in eletroplating as-is or need to be refined? If yes, how? Put your brains to work, my friends! A silver-coated soldering iron tip is something of our common interest, i believe.

Why have neutral plates in an hydroxy generator? Answered

Hi all, I've been wanting to build a simple hydroxy generator for using it as a torch.  I've seen about 500 gazillion tutorials and alot of them talk abour having 3-5 neutral plates between each positive and negative plate. What is the point of this?  Isn't it better to have all plates connected as electrodes? Also, what's the difference between having 5 neutral plates between positive and negative plate, and just having the positive and negative plates installed farther apart (same distance as if you had the neutrals between them)? Thanks!
