My husband is upgrading his Benchtop Mill and has asked me to construct a new set of lower cabinetry that it will sit on. My concern is the mill weights around 850 lbs. The top will be constructed like a work bench with the individual boards on edge and be approx 3.5" thick. He wants "kitchen cabinets" under this top. I know normal kitchen cabinetry is rated for 600 lbs. I expect to use 3/4" plywood, and my usual method is dowels, glue and pocket screws to hold it together. What can I do to handle the extra weight?
