Annoyed with myself here because I've cut a 10" square from the remaining aluminium sheet, whereas I should have cut a 12" insert and lopped diagonals off each corner to allow for the uprights. Nonetheless the art of prototyping is much like the progress of a battle, driving ever forward regardless of individual defeats upon the field.
This section forms the platform for the passenger and it's affixed to the interior rather than to the outside because for this working model I've chosen to support connecting rods with bolts in the floor. In case these fixtures come loose we will need access to them from both sides, which would not be possible if we sealed the underside.
