After a day of jointing, planning, ripping, cutting to length, and dadoing, John Smith and Bob Milhaupt have a stack of parts for two car frames and some spacing jigs, plus some extra parts. The stock at the left of the picture is leftover stock from the frame parts, plus all the stock for the decking. All the lumber we used was White Oak, which is considered to be good material for outdoor use. Modern treated lumber was not used due to concerns about chemical interactions between wood treating materials and the fasteners used in the car construction.
