This weekend I fiddled around with some minor things. The second shaft bearing was made and the gearbox built in.

The gear box was fitted to the ground plate and aligned with the shaft. For vibration dampening the gear box was underplayed with 2mm strips of sponge rubber.

Then, I built a open box from 1mm polysterene drilled a duct for the stern tube and the box fixed under the shaft with glue. In a second step I poured 5mm epoxy into the box to give it some stability. After 12 hours of hardening the ducts were sealed with glue as well then the rest of the box were filled with epoxy.

The shaft bearing turned out to be very solid and runs smoothly and calm in a dry test. I am looking forward for testing it in the wet element.
