After receiving the plans, building could commence. The suggested way of doing this, is to glue the patterns to the MDF, and cut along the lines. I found this to be a tad brutal to the pattens, and chose to glue them to some carton and cut along the lines. This way, I had a set of relative strong templates I could use to mark where to cut. It is possible to make minor adjustments before cutting, and if I ever need to make spare parts (or another car), The templates will come in handy.
A land Rover Series II is built on a frame, with a body made from aluminum and steel bolted on top of it. A Toylander II is built from moisture resistant MDF or plywood as a unibody. I initially wondered whether to use MDF or plywood. Both materials have approximately the same weight and cost, plywood is probably somewhat stronger. MDF on the other hand is easier to work on, and will give a smooth finish with less work. I chose MDF.
It takes a bit more than one sheet à 120x240cm of MDF or plywood to make one car. (I guess you can make 3 cars from 4 sheets). To cut the parts takes a few evenings. The parts are glued and screwed together using 19x19mm battens. I was surprised to see how well the part fit, and the body tub has a construction that makes it very solid and rigid.
When building the body tub, I mostly followed the directions given. Some minor adjustments was made, like using model plywood, not aluminum, for the curved part of the front panels, and to make the seat back removable to allow grown-ups to drive the car.
