The existing design was a small wooden toy plane purchased at the Thrift Shop for the CLUB for BOYS, of all places. The wheels on the plane were considered to be too small to be safe for kids, as the industry standard for wheels for kids is 1 1/2 inches. Therefore, we increased the size of the design to accomodate the larger wheels. Then there were other considerations, such as thickness of the fuselage, the thickness of the wing, and the method for attaching the wheels. Other options including adding a propeller, tail stabilizer, or a window was discussed, but it was decided not to include them for this phase of the program. After these options were discussed, several prototypes were built to help visualize the design.
The first tool needed was a fixture to hold the wing for drilling a hole for the attaching screw in the exact center of the wing. The second tool that was needed was a fixture to hold the fuselage at 90 degrees while the wing was attached. So work began on these fixtures.
The fixture for holding the fuselage at 90 degrees to the wing was made using the other half of the cutout from the fuselage.
