drill plexi easy or it will crack, don't force the bit into the plastic. Buy some faucet washers to put under the screws so the plexi doesn't crack when you tighten the screws. You can also buy plastic washers at the hardware stores instead of faucet washers, but faucet washers compress more. You can get plastic washers that are the same size as guide flag spacers you buy at the track. They are about 16 cents each locally.
