Another Christmas present for a granddaughter. Great toy hauler. Baltic Birch. Wheels took some figuring…3/4 plywood circle with 1/2 shallow rabbet around the rim to accept a rubber vacuum cleaner belt for the tread. Axle is 1/4 bolt through a 1/2 inch nylon bushing lubed with bees wax and screwed into a t-nut. Used a template with a flush-trim router bit to make slotted basket.
