I've only copper plated a few things in the pickling tank at a place I used to work that made heat exchangers. I didn't really know what was going to happen, but just popped the lid on the forklift, connected the jumper cables + to the part and minus to a scrap strip of copper, and dunked them in the salt and vinegar solution(which was well used and had a lot of copper in it already). It turned the steel part copper colored pretty quick and it lasted for a long time.
I'm not sure what kind of solution is used to gold plate something, but it's only a google search away.
Glenn, for some reason I'm seeing your wife a week from now wondering where he gold jewelry went :D

Harold, Nice! Is it feasible to try to gold plate something here in my shop?
It is, but it's not simple due to the difficulty of obtaining cyanide, which I used. I had some on hand (used for extracting gold from a high grade gold/silver ore I processed for a customer), which is the electrolyte I chose because it's simple (assuming you can acquire cyanide). Gold chloride is dissolved in cyanide, making the required electrolyte. A rather generous amount of gold is required. Current regulations make buying the stuff (cyanide) virtually impossible for the common man. However, a guy can buy a small container of electrolyte, already prepared, from a jewelry supply store. With it, you don't have to have a gold anode, but its life is rather limited, as the gold you plate on the object is already charged to the electrolyte and is depleted with use. By using a gold anode of the proper size, you can plate a lot more, unless you contaminate the electrolyte. You likely understand the electrolyte so purchased is not cheap. You may well pay more than twice the value of the gold contained within.

One of my customers offered to nickel plate the spike, so I didn't have to prepare the bath for that operation. It's critical to success, however, and should not be overlooked.
I’ve got a bit of gold lying around, and plenty of 3 1/2” spikes, but never attempted such a thing, other than electrolysis.
The gold you have lying around isn't likely to work unless you have some that is pure. That's assuming you hope to apply a pure layer of gold (which mine is). If not, alloy will likely work, so long as it's yellow gold. In a cyanide bath, copper and silver will deposit along with the gold (both of which make up yellow gold jewelry), so you'd be effectively plating with the karat gold you used as an anode. The only issue, then, is that you don't really get a true gold color, but the level of protection would likely be quite good. You should also know that a base layer of nickel is generally applied before the gold is plated, as I mentioned, above. Nickel provides a needed barrier, as gold (and silver) readily migrate, especially on copper. Given enough time, plated objects will appear to have lost all their plating.

I am aware that there are other electrolytes that are used for plating gold, but the chemistry of them evades me. I fully expect they would be just as difficult for the home type to pursue.

Wow that got done quick Glenn!
I too read up on the gold plating, I think the $20 spike you found sounds like a bargain after reading about the different nasty acids and highly poisonous cyanide used.

Glenn:
Just get a can of gold spray paint for the spike,
and spend the rest on a nice bottle of single-malt Scotch to celebrate!

Russ, I thought about a can of gold paint- actually I just now remembered one in my paint locker - from 20 years ago. Have to go see if it still works. I did order a plated spike from the guy in Calif. it’s 6” long, so I plan to lop off the bottom 3” and grind the end to a bevel, so,it drives into my “Commemorative Golden Spike Tie” my boy and I laid under the rail.

After some roadbed testing, we plan on throwing a Golden Spike Celebration and BBQ for the neighborhood and any Chaski fans who can make it.


Ryan, yep highly motivated to finished this beast and send the extra gang on to other things. Like pulling weeds and mowing the grass.

Pretty good weekend so far. Laid in 16’ of cribbing and fill, then finalized grade for the third car siding leading off the turntable. Today hoisted and blocked the poor old Yard Goat up off the ground and pushed her onto the turntable in preparation for a move onto the soon to be new third siding. I’ll be storing the Loco on the siding until I can get into a tear down and refurbishment.

Plus I needed to move the goat out of it’s place of honor in front of the shop so I would have room to load my 4-4-0 steamer onto the turntable from the shop. So, first things first.

Kind of a multi step process with the engine hoist. Lifted the Loco 2’ in the air.

Then blocked a welded section of track underneath, connected to the turntable on one end.

Then back around to lift the front end and push onto the track. Rolled surprisingly easy after being out of service for 30 years.

And there she sits awaiting transfer to the new siding

It’s kind of an ugly duckling, but was hand made by Frank Griffens, the previous owner back in 1968 and has potential to be a nice little 25 ton road switcher replica. Supposedly this was a free lance replica of the yard switcher Frank operated at the Everett rail yard in the 1960’. I plan on preserving the Loco by lowering the cab roof, adding window detail, and putting a new set of prototypical trucks and proper size drivers under the frame. With proper sized trucks and drive wheels, and a more realistic cab, + some shinny new red high gloss paint job - maybe a nice powder coat, should turn out just fine. Also need to strip down and rebuild the old Wisconsin one lunger motor. Right now it turns over with remarkably good compression. So hopeful it can be cleaned up and used, just as Mr. Griffens intended.

This garden railroading is way more fun with bigger engines to mess with!

Looking good Glenn!
Regarding the yard goat, I see your concern with the trucks, they look like little freight car trucks. I'm sure we could make something pretty realistic from plate along the lines of those 44 Ton trucks.
Are you going to narrow the body or leave it full width as it is now?

Ryan, I think the trucks were taken off the missing Ottaway passenger car. They look identical. Very small and undersized for the frame and body.

I’ll probably leave the body the same width and height, just do I have time to work On the much bigger job to restore the old 1904 Campbell 4-4-0. A nice set of trucks for the yard goat would go a long ways towards making it more useful. Might be able to head up to Bham next weekend, if you are around.

I will be around Sunday afternoon into the evening, Friday and Saturday I'm tied up unfortunately.
Getting close to exciting times, ~2 weeks until the laser arrives. :)

Ryan, I’ll try Sunday afternoon. I can bring the side frames also, if you are still interested in swapping them out.

I certainly am interested in swapping, I'm working on a fixture tonight so I can start TIG welding up the truck assemblies so now would be the perfect time. I should have a semi-assembled truck frame so you can see how it works too. Sunday afternoon will work fine. I'll PM you my information in case you don't have it anymore.
