My familiarity with manufacturing hardwood furniture has taught me that about half the time involved in constructing each chair, table or cabinet is taken up with sanding. When you are trying to make a livelihood in the woodworking industry with hourly employees you must cut inefficiency to a bare minimum. This does not mean becoming a tyrant but, instead, removing any and all impediments that may be slowing construction, sanding and finishing.
