Finished the floating HotWheels sammich. Positioned and stuck the right side on with its adhesive tape. Then filled in the spaces around the floating arms with 3m mounting tape to compensate for their thickness. Then mounted the left side with its adhesive tape and squeezed the sammich together.
Well I am done working for the day and I think I am done with the build. We'll see after the ride. Got about 1.5 hours of daylight left. Still just testing the mirror, but it may stay.
