5. Securely clamp the cut Lexan sheets onto the expanded metal screen aligning the outer
edges, this can be done upper or lower sheet first. Using a 3/8" drill bit drill the mounting
holes through the lexan sheet in a pattern as in Figure 2. When drilling the holes in the Lexan
Sheet use the drill to mark the metal frame of the expanded metal screen on all the holes.
When all the holes are drilled into the lexan sheet and marked into the metal frame, remove
the clamps and the lexan sheet.
6. Using a 1/4" Bit, drill the holes into the frame of the expanded metal screen with the Lexan
removed. Note you drilled 3/8" holes in the Lexan and 1/4" holes in the frame work. This is
so that the Lexan will not have a binding fit.
