Electroplating At Home

Just noticed that my Accutron which is humming nicely still no longer looks as "golden as it used to".  The sides are really worn now and look more like nickel or SS whilst the back which is separate is still in really good condition, this after only about 8 months, though I did wear it continuously for about a month in LA and was hot and sweaty most of the time. 

 

I have a couple of 10k Accurton cases and may swap it over. But I would not sell this case on to anyone.  I think that the person I bought it from must have used an immersion kit to give it a good but quite temporary shine.

I was wondering if anyone has dabbled in home plating.  I have a bit of old gold in my drawer so the raw material is there.  I believe the solution can be made up by dissolving gold in a Hydrochloric / Nitric acid mix and then you are looking at the transference via a current through the liquid.

 

Has anyone tried this ?

 

Cheers,

I think I will look into it.  It seems like an interesting and potentially usefull thing to be able to do, especially with old watch cases or even crowns. 

 

I like Bobs info particularly the electroplating in miniature part. 

 

I think that one of the highest costs is the soulution itself and if we can get that bit sorted out it might be quite feasible.  Worth a shot anyway.

 

Cheers,  Vic

Glad you can do something with this one. If you launch yourself into it first, please let me know. I'm in the process of getting a watch waterresistant tester so this one might have to wait lest the wife squeals! :)

Thanks Nigel, I will PM you about it.

 

Still tied up with the amp but always on the look out for something new and interesting.

 

Bob's suggestion is looking good as those small kits are available in the UK as well.  i think the most costly thing is the electrolytic fluid, if you can make that yourself I think the problem is largely cracked.  Lots of nasty chemicals involved but nothing I have not used before.  Muriatic Acid is, I believe just Hydrochloric acid which is available from most DIY places as it is used to wash down brickwork - further research needed :D

 

Cheers,

I used to have a big plating machine. There are two main kinds of plating, flash plating and hard plating and I used to do both with it.

 

Flash plating OK for anything that will not come into contact with your skin as it will wear off very fast. This is more useful for plating watch hands or movement plates etc. not so much for plating cases due to the lack of durability. The pen plating kit falls into this category.

 

Then there is hard plating. This is suited for watch cases as the plating is more thicker, typically 5 or 10 microns or more. The hard plating solutions are very prohibitively expensive for one-off jobs and you need an agitator as the piece needs to be in the solution for a long time and always on the move.

 

Some materials (like brass) will need a base coat (nickel (poisonous), Rhodium (expensive)) to start with as you cannot gold plate directly onto it.

 

I never managed to plate onto SS as I never had the knowledge or equipment to do so.

 

I am by no means an expert on plating, just a complete novice really. I keep a pen plating kit as it is useful for touching up bit and pieces on occasion. But I would say that plating onto a SS case could be very difficult and I would rather send the case in to a pro.

 

Be warned though - if you do get into plating (it's fun) then you will be looking all over the house for stuff to plate :D

 

I hope this helps.

Thanks for the info Mark. 

 

I take it that you purchased your electrolyte rather than made it up yourself.  It seems like that is the main cost. 

 

I just thought it may be interesting and a bit of fun and you have confirmed that.  I am still on the research phase but it seems like it is not too difficult but some of the chemicals are a tad nasty.  Loads of stuff on you tube about it - one is a guy from the uk using household cleaners to make up the electrolyte !? I have not seen all of his Vids yet but had to laugh as he explained that there was a US patent which he could not infringe then proceeded to tell what the constituent components were.

 

Cheers,

Never made my own salts - used to purchase from CooksonGold.com or HSWalsh

 

Now I just use a pen plater and I only use that a handful of times a year. There are sellers on eBay with kits at a reasonable price so that may be the best route because the kits from Cookson or walsh are quite pricy.

Mark this is amazing information only gotten by experience. Thank you for the heads up. I'm also -- eventually -- planning to get into plating! Therefore my previous posting.

      A lathe with indexing that won't break the bank?

      I believe @nickelsilver has a setup like that.

      I posted pictures earlier in this thread. My lathe and mill are two separate instruments. I think I have seen examples of putting a milling head on a lathe bed...but not certain.

      Watch of Today

      By Rocco · Posted

      Timex Camper, September 1994, new to me. Strap is an old perlon with "Germany" in script etched into the resin on the tail end. Not Horlon or Eulit I believe. History unknown, running strong, losing less than a minute a day. Goals for this: Wear it a ton! Buy crystal lift, clean out the gunk around the ring and under the crystal Eventually swap into a stainless steel case. I've seen a member who has swapped a Timex mechanical movement into the Timex J.Crew quartz field watch case.

      One of the problems we would have with a watchmaker's lathe is they were made over considerable span of time and manufacturing in the early days probably wasn't as good as it was today. Then if you look at the older catalogs typically it was just the head a few collets and something to rest graver on. So basically a basic lathe with over time things acquired but acquired things may or may not fit. Order today you purchase a used lathe that all kinds of nifty bits and pieces from a seller that acquired from? This would come back to that the basic watchmaker's lathe was used for basic watchmaking like turning things with a hand graver. Then limited indexing is fine because you can make things like stems Which don't need a whole bunch indexing   In the link above the word vector is mentioned and at the link below you can purchase one. Then of course you're going to need the motor that's a little bit extra for the price. https://www.hswalsh.com/product/lathe-vector-watchmakers-48-collets-hl11. That you're going to need some bonus parts like these found this picture online show the classic way of classic gear cutting.   The lathe could have a much bigger indexing disk but it has to be mounted close to the edge. Otherwise you're going to have a whole bunch of smaller disks like this which I think has notches rather than holes. Then as wonderful as these pictures look actually cutting a gear with this is not entirely fun. Look at all is belts all pulling on things and this is a watchmaker's lathe lightweight with lots of bits and pieces attached. It would make more sense if you actually cut a gear with something like this and it tends to be it's not really the best way to do it looks nice on paper but it is not the best way to go. Reality for cutting watch parts would be a bigger machine is much better. Than getting rid of all those belts and pulleys also good. Here is an interesting channel I would've liked of found a different video but this was nice and short if you look at his video as he uses a stepping motor and worm gear assembly for the indexing plate. In this particular video it gets attached to the lathe at about one minute and seven seconds and it looks like it's hiding looks like he has a Sherline. I do know he's had other stuff you'll just have to go through his videos to find it. Then at about one minute and 22 seconds you find out if you set up things appropriately. It's always bad we end up with half a tooth at the very end. Then you will note big lathe yes he's getting a big gear but you could easily cut a watch gear with the setup. And it definitely way more stable than a watchmaker's lathe.         Oh here's a company they been in business since 1911 http://www.fwderbyshireinc.com/
