I need to build a table to mount my Bader BII on and was wondering how heavy it should be. I am sort of space limited, so wanted to build a small bench that I can move out of the way when not in use. Maybe 30" by 30" top or something similar with 4x4 legs and a 3/4 inch plywood top. Would this be heavy and sturdy enough for grinding. I could also build a bracket to fasten the bench to the wall when in use to provide more rigidity. What kind of bench do you use? Ken
