How to Build a Swing Plane Board for Golf
Slide on a pair of work gloves, a dust mask and safety glasses to protect your skin, lungs and eyes.
Measure and cut a piece of plywood 4 feet by 8 feet. Sand the edges of the board with 80 to 120 grit paper. The 4-foot height allows for the board to extend under the shaft of the club and your arms. The 8-foot length is appropriate to craft the downward looping motion of your swing.
Cut a downward 45-degree angle at both ends of the two 2 inch-by-4 inch pieces. These two pieces should now resemble a polygon, with both ends angled in toward each other.
Ask an assistant to hold a protractor upright on a flat surface. Ask a second assistant to position and hold the bottom edge of the plywood board behind the protractor. Ask the second assistant to angle the board at a 50-degree angle, which is the lie angle of a golf driver.
Take one of the angled 2 inch-by-4 inch pieces and position it underneath the left side of the plywood board. Position it so one of the downward 45-degree angle edge is flush against the board. Side the 2 inch-by-4 inch piece down until it naturally touches both the board and the ground at the same time. Trace outline of the 2 inch-by-4 inch piece that is touching in the board. Repeat with the second angled piece for the right side.
Place the plywood board on a flat surface so the underside faces up. Bracket each angled 2 inch by-4 inch piece into place using wood screws. Secure each angled leg to the board with two brass brackets, one on each side.
Center the third 2 inch-by-4 inch piece flush to the bottom edge of the board. Secure the piece here with wood screws to act as a support beam.
Flip the board upright with the help of your assistants. Place three evenly spaced bricks behind the support beam whenever you use the board for extra stability.
