The outside of the timing light (the “box”) may be constructed from any kind of wood. I have created versions of the Timing Light using 1/2-inch Pine Boards, 3/8-inch Pine Boards, 1/4-inch Red Oak Boards, and 1/4-inch plywood.
Instructions and dimensions on this web-site are for constructing the box out of 1/4-inch boards. If using 1/4″ boards, you will need the following:
- 1/4″ x 5-1/2″ x 4 ft (1)
- 1/4″ x 3-1/2″ x 3 ft (2)
- 3/8″ x 1-1/2″ x 2 ft (1)
- 1/2″ x 1-1/2″ x 2 ft (1)
- 1/2″ x 1/2″ x 3 ft Square Dowels (4)
If using plywood, the 1/4″ boards listed above can be replaced by a 2 ft x 4 ft piece of plywood.
You will also need paint or stain and polyurethane for finishing the box.
