Do-It-Yourself Story

I remounted the microwave after installing a 3/4" board in the recessed part the support cabinet. This allowed me to get accurate measurements for the bolt holes, a stronger support system, and it avoids the probability of breaking through the particle board cupboard bottom. When tightening these bolts, do not use a drill, only tighten by hand with screwdriver. These bolts were a little thinner than the manufacture stock, but they worked just a well. It's beneficially to have some washers as well to avoid damaging your cupboard.
