A couple more photo's.
A few pieces of linkage and the vacuum switch have Eastwood's yellow/gold "zinc" paint on them, I don't recommend it, the color just isn't right.

Not that any of this matters really, just curious.

I've been all over the web looking at paint colors and the rolled lips. I'am just going for the 1/4" once I figure a good way to do it. Still deciding on how much shine they had.
