Sprockets have arrived and are being machined next week hopefully.

Painting bits I hate this job the main chassis has lots of holes drilled for different things and every one traps the paint and when you are not looking starts a paint run.

Silver hammerite for the inside and blue smoothrite for the outside.

The new ratio will be 466.6666/1 this works out at about 4 seconds for 90 degrees. Should be ok.
