The card model.
I figured that I could build it using the card model parts as templates and duplicate them using wood, brass, styrene and resin. These duplicate parts would then be covered with the relevant printed card parts thus getting a perfect colour scheme finish from the printed card.
The running boards were made from printed card and attached to the chassis with wooden brackets. The picnic hamper was made from a block of Jelutong and bound with brass strip. All the printed card parts were coated with a layer of white PVA glue to protect them. This dries clear and is as good as a coat of varnish but has the added benefit that being an adhesive, it fortifies the existing glue joints.
The bridge was made next. This consisted of two side frames with planks on top. The legs of the side beams were fitted loose so that the assembly would fit through the neck of the bottle. Once inside, they were glued to the longitudinal braces.
Four planks were fitted at the rear of the bridge and two at the front and when set, the temporary spacers were removed.
The three parts of the chassis base were now inserted and together with the picnic hamper, were joined together and glued. The wheels were fitted and then the chassis glued to the bridge planks.
The seating cabin was inserted and joined together.
