Copper-nickel-chrome process is what is referred to as triple show chrome. Not all parts get the copper.

Great clip that one Pete.
I bought a kit.
The only thing i have left from that is the containers and the passivate for colouring stuff the Goldie straw colour.
Great for plating a few things at once . Once i started using the power supply repeatedly it burned out and the amp controller ( a variable resister) lit up like a bulb and melted .
I arrived at much the same as in the clip except for producing my own solution and the current controller .
The plating on my TDR 250 has lasted well and is durable by using that method.
Good quality nickel anode is easy to get as stated in the clip.

Dave, I searched for Nickel plating and this was the video that came up, so I copied his method.
The guy's squeaky voice bits made me laugh.
It seems to work fine for me and I'm very happy with the results.
My take on the "keeping things original" isn't necessarily keeping the finish absolutely original but trying to re-use the actual parts that came with the bike where practicable and having fun

Yes, i'm on the same way of thinking about using the stuff what's there rather than substituting with various aftermarket items.
I don't like the use of spurious screws and bolts and never use stainless cap screws . Mr Mega pack stuff. Nothing wrong with the quality but they just look odd when used on this era of bikes.
Just thought on something with plating that Mark T said. I might try copper plating the ornate stuff first see if it will fill in some of the corrosion pock marks that are eaten in see how it goes.

How the show chrome (or precision industrial chrome) places use the copper is somewhat like a "primer filler". They copper plate and then buff down... then copper plate again, then buff down... repeating until the imperfections are filled.

Nice one Mark. Yes so the inclusions get filled until it's no longer an inclusion. Then final plate under the nickel over everything ?
