Thanks, kvom.
I was thinking seriously about the CI/steel pairing for the eccentrics. Always good to have a reality check from someone with more experience.
I could use some advice on which grade of bronze to use for my projects.
The plans I have spec bronze for such things as slide valves and eccentric straps, but they don't specify which bronze alloy to use.
Tho only bronze alloy which seems to be available in rectangular flats is aluminum...
I don't remember where I saw it, and I've googled until I'm cross-eyed with no luck.
A builder posted some pictures of some aluminum engine parts that had been bead blasted and then gold anodized. The parts had a beautiful, perfectly uniform satin gold finish that I wish I could duplicate...
