I just completed my new workbench. Plan was from American Woodworker
about a year back. Met my needs because it rolls when I need it to but
is rock solid when in use. I used the plane for the base and is made
mostly from 5 sheets of borg plywood. Trim is solid oak. the top is
made from a solid core door cut to size and trimmed in walnut. There
are 6 100 lb rated wheels under the carcass to allow for movement. 4
wedges lift it slightly to make it stationary.
