This is another leading seller. The Bell Tower Marble Machine is based on the bell towers of Italy. A unique wood crank elevates marbles up through an acrylic tube to the tower’s loft to ring a bell. Marbles are switched to one of two pathways to chime more bells, sound a xylophone then swirl and zigzag over multiple pathways. Sources are listed in the plans for many of the needed parts. An heirloom wood project. 44″ tall, 19″ x 19″ base. For intermediate to advanced woodworkers. Our 11″ x 17″ plans take little workbench space. The copyrights allow making a photocopy of the full size patterns. Trim out the patterns, apply spray adhesive on the backs and place on stock prepared to the thickness noted on the pattern. You get accurate parts and no tracing. We mail fast, usually within one business day.
