The rolling cabinet with its optional workbench top makes an ideal base for the tool chest. Three half sheets of plywood (5/8", 1/2" and 1/4") plus 20 board ft. of hardwood (10 board ft. without optional workbench top) are required. Either biscuit or dowelled joints can be used. A sliding tool/drawing tray leaves the top clear for working. Overall size is 18-1/2" x 26-1/2" x 34" high (with casters).
