INSTRUMENT SHELF HOLE PATTERN
The figure below shows the hole pattern for the riser box. You need to drill two 3/16ths holes. The first
hole is 3 inches from the end of the work surface and 3 inches from the top of the work surface. The second
hole is also 3 inches from the end of the work surface; however it is 10 inches from the top of the work
surface. The holes are to be placed using the same dimensions for the opposite side of the work surface as
well.
