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.
