I'm on to a new process for cleaning and coating these chassis
I'm told it can be done after assembly and the finish will take solder well
So I found an old delinquent Mack Speed as a donor to test, before committing any new chassis to the same treatment

There's a product that's often discussed in some of the YouTube machinist channels called "EvapoRust". Has anyone tried it? I seems to work without pitting the base metal (it's made for ferrous metals) and leaves a fairly decent finish.

Steve,

 

Can the chassis be cleaned that still have the ball bearings installed?

No, BB have to come out otherwise they too will get coated in nickel. The process doesn't discriminate any steel item....

My wife uses it on old sewing machines she restores.  Works well on steel and iron, but I don;t know how it may react to solder joints.

Sadly, tumbling doesn't polish steel like it does brass :(

On the tumbling thread there were stories of blackened and stained steel. Not sure if it was the water or the tumbling media.

So......Still not clear.

What was the solvent/chemical that was used in the photos above?

Was it the "EvapoRust" mentioned above or a different chemical?

No, it's a non-electro plating of nickel. Very thin, and very lubricious
Didn't weigh it sorry KvP, will do some more. Have a brand new Dubick to do so will weigh this before and after

I'd love to see some photographic evidence in support of your claim :)

Steve,
Is this a NZ State Secret or can you tell us what this process is? I'd like to see if there are any platers doing this here.

I'd like to nickle plate some brass tube like we used to be able to buy in the 60's.  Made for really good looking chassis.  Would also be good for repairing some old Champion chassis too.

Good ol' electroless nickel plating.... I did a lot of that in the 70s. Made up solutions, ran parts.. Computer drums and disk for memory... you probably have less than 40 millionths of an inch on the chassis.
