Here is one example of a multi-colored body.Glue two pieces of 15/16" x 3/4" walnut and one piece of 1/8" x 3/4" birch together to form wood for body. The birch forms a stripe between the walnut.2.Trace pattern onto helicopter body.3.Cut out the body using a band saw. Leave the line!4.Sand the helicopter body to remove band saw marks using the line as a guide.5.Use a router with 1/16" round over bit to round edges of body. One may also use sandpaper to round the edges.6.Use sander to round end of blade and drill a hole in its center using a 15/64" drill bit.7.Drill the hole in the top of the helicopter for the blade. Use a 7/32" drill bit. It should be deep enough to hold the blade axle.8.Drill the front and rear axle holes in the body. Use a 13/32" drill bit. The centers of the holes are located 5/16" from the bottom and about 9/16" from the front and back.9.Assemble the blade axle through the 1" wheel and blade. Glue it in the hole in the top of helicopter body.10.Cut front and rear axles to length. Assemble axles in axle holes and glue dowel caps to ends of axles.11.When the glue has dried, ensure all wheels still turn freely and can not be pulled off the body. Check for rough spots and sand if necessary.12.Apply mineral oil to the wood and let it absorb overnight. Mineral oil is used because it is an eatable oil so there is no harm if a child puts the toy in its mouth. It is available in drug stores.
