I routed three copies of the little One Track Mining Co. vehicle chassis. I'll make three different models as per the original sketches. The pieces were routed from some scraps of 1.5" 30 lb Precision Board. Since I uses a tapered 1/8" bit the track shoes routed just as I imagined, slightly thinner at the edges. I had routed the pieces with a 80% overlap which provided a smooth surface. I left a thin onion skin layer against the spoil board so the small pieces stayed put on the vacuum spoil board on the router.
Here's the same there pieces pulled apart. I simply blew the dust off the pieces with an air hose before I glued them up using a five minute epoxy and five clamps.
Once the epoxy set up I used the air powered die grinder to even out the edges. The corners and back of the hood were rounded to match the radiator cover. I'll cut and glue a little more material to the base to widen it before I start the sculpture process.
Before I started the sculpt I did up a new rendering of the wheelbarrow vehicle based on the little scale model as the engine housing/hood wasn't in my first renders. I'll do my sculpt with this new drawing as a reference. The hardest part of this build is that it will have to wait two weeks before I do it as I head out of town bright and early tomorrow morning. :) Stay tuned...
