Tools Needed: Scroll Saw or Jigsaw Router with 1/8" Round Over Bit (Optional) Electric Sander (Optional)
Drill & Drill Bits
Download and print vehicle template. Cut out. Trace patterns onto your pine board - I traced 1 of each plus an extra car to make 4 total.
Whether you are using a scroll saw or jigsaw, drill a large enough hole for blade in each vehicle window. Cut pieces out.
If you choose to, use a router to round over all your edges with a 1/8" round over bit. Sand all edges smooth. You can see in the picture above the difference between the rough car and the routed/sanded car.
Drill holes for wheel axles and propellers for helicopter over each of the cross-hairs from template patterns. For the wheels you want the holes slightly LARGER than 1/4" so your wheel axles will turn, for the propellers you want 1/4" holes. Paint vehicles, let dry and lightly sand smooth.
Glue a wheel onto each dowel piece and set aside to dry.
For the propellers, rip a 3/8"-wide strip from your pine board, at least 8"-long. Cut a 5"-long piece and 2"-long piece from that. Drill a 1/4" hole in the center of each.
Attach wheels and let dry. Sand axles flush with wheels if you prefer (I didn't).
