Cub Scouts Space Derby Binder Winder Plans

You are bidding on plans to build a "Binder Winder" for winding up Cub Scout space derbys. This machine will wind 4 space derbys at a time and will also count the number of rotations. Included with the plans will be a parts list which can be used to order the parts from a reputable industrial supplier, assembly instructions, and working prints with dimensions to show the locations of holes to be drilled and cuts to be made. This machine is a "must have" for running a space derby. You can view a short video the Binder Winder working by clicking on the link /watch?v=X2ghBtUj7HU
