Made from one piece of Maple, used to be an old bench, 1 1/2" x 6", cut down to (1 1/2" x 3 7/8" x 96") no screws, only glue and dowels allowed to build up the machine. Dowels made also from the same piece of wood.
I saw the same machine on u tube, constructed by Paul Grundbacher, he gave me the OK to make it for the challenge.
