Engine cradle plating?

Postby rcousine » Tue Oct 10, 2017 11:20 pm

Hello all, back with more fun questions about my 1958 CS.

There’s a pair of stamped plates that hold the engine, transmission, and generator together, and there’s another stamped and bent plate that the magneto perches on.

All of these look like they are plated; does anyone know by what process, eg chrome, nickel, cadmium, zinc?

I’m thinking of getting them re-plated, and want to know what would be correct.

Black paint as far as I know.

when I got the parts for my bitsa CS there were alloy engine plates in the box so I used these, I'm pretty sure thry had been fabricated by the p/o and I would agree with Rob originally they would have been steel and enamelled. kind regards

Thanks all! Mine look plated and unpainted, but I’ll take a closer look, and whatever I do, at least I know what’s normal. Of course, they also look welded from two pieces, and that seems odd...

I have been told from a reliable source that butt welding of engine plates was normal for CS models around this year.
