The smokestack and monkey drum were built as meshes using the revolve tool. These were then combined with a zero height relief. The zero height relief was also modified with the egg shipped relief and the dome tool. Two of these would form the basis for the elephant’s head.
I then duplicated and flipped the various pieces to create the front and back of the train engine. Everything was then ready to tool path and send off to the router. I machined all the pieces from scraps of 2″ thick 30 lb Precision Board. Between the engine and the two cars and various bits and pieces we used up a big pile of scraps.
As soon as the pieces were off the router it was an easy task to screw them together. There was a front and back as well as two layers of 2″ thick cutout for the centre. The next step was a bunch of hand sculpting.
