Operation Dirty Penny - '75 Merc 240D

[mikey G]

No title and rusted to shit? Otherwise doooo it
Can't be that bad and will be paid for when you sell a door handle from the RR lol

If you get it I forbid you from working on another car until

A) The RR is a rolling chassis w/ frame
B) Penny is completely copperized.

So I found a W128 for sale for $1800 in my town today and I really want to do it. The guy doesn't even realize what he has. Thoughts?

do it, you obviously have skills enough to take on 3 projects

well what kind of condition is it in?

imma gunna say, that doesn't matter for op

also if i'm not mistaken (on phone) don't these come in 3 models?

If it's not a wreck, and you have $1800 and a spot to store it, I fail to see any downside.

Well considering his shop is the size of my house and his RR is worth more then my house he should be okay.

Aww man, all the copper plating pics aren't working for me. I saw a glimpse of it on one of the welding pics on page 11 tho. 'Dis gon' be gud.

Finished cleaning up the rear deck. Got all that nasty glue shit off and put a coat of primer down.

+1 I know nothing about plating so seeing it done outside of a giant tank you dip the parts in is very interesting. Keep up the amazing work sir!

I'm still curious how you do the copper plating without dipping it into a bath. Pls give us some science lessons?!

There's brush electroplating which is the most common for difficult items such as this. Same concept as electroplating in a bath, but more controlled. There's something called electroless plating too which is a chemical reaction, but that requires a tank.

What you see in the pictures is none of the above though. Its actually more of a copper deposition using copper sulfate and sulfuric acid. The result is similar to what would happen during immersion of a part into a electroplating bath without going in "hot". The copper sulfate in the solution will instantly bond to the steel, but its only a very mild bond. I had to go through a lot of trial and error in the technique to get it to form a strong enough bond that wouldn't continue to oxidize and wouldn't just wash off. I got the technique down pretty well, but I have to be really careful polishing it with metal polish as when I work it too hard it takes the copper off in some spots. I'm working on getting the materials together to just brush plate it now because I'd like to have more durability in the coating. If I were clear coating the whole thing then it wouldn't matter, but I want to leave it raw again.

Just a heads up guys, if anyone will be attending SoWo we have one more spot open for our booth. Currently we have the dirty penny, my mk6 and a bagged R8
