For L Shaped Workbench, (Two benches joined at a right angle) select the two workbench sizes from the Kennedy or Grant series.
Put an "M" in front of the part number of the longer workbench. This will be the main bench which the shorter workbench will attach to at the right or left side of the front edge.
Put an "L" or "R" in front of the part number of the shorter workbench depending on whether you want it attached to the right or left of the operator.
Notes: There are advantages and disadvantages to our design. There will not be a leg in the middle of the operator side of the workbench, but you can only use the longer workbench separately. The short workbench will not have legs on one end. Adding legs later will make a bench with the frame extending out from under the top.
