ZF transmissions got nothin on this

It’s almost done. The disc is a 400 lb, 1/4" thick, 4' diameter hunk of machined and inked brass. It came in on Tuesday morning. Final installation is tonight or tomorrow. The sun is glass, and the planets are printed.

Here’s how it looked with a printed plastic piece in place of the brass, during the first test fit.

What a crazy project.
