A friend of mine recently removed their dish washer and would like to have a three drawer system built into the remaining opening. The drawers will be 35″ wide and 28″ deep. The bottom drawer is intended to be used as a pot drawer and will be approx 15″ tall.
My question is what thickness of plywood will be sufficient for the drawer bottoms? Is there a chart or calculator to find out the allowable span for different thicknesses?
