Online Rocketry ToolsThe Parts Finder tool helps you locate hard-to-find rocketry parts and supplies and to save money by pointing out lower-cost sources. The Study for Certification Tests tool provides online help to prepare for the NAR or Tripoli Level 2 written certification tests. The Centering Ring / Motor Mount Tool prints a template for a centering ring or motor mount. The template can be printed actual size. The parameters you enter to define the ring match those used by Balsa Machining Service which makes this tool useful for 'visualizing' a center ring or motor mount before ordering it from BMS. The Transition Tool prints a template for a transition from one size tube to another. The template can be printed actual size. The Fin Wrap Tool prints a template for marking fin positions on a body tube. The template can be printed actual size. The Fin Guide Tool creates a template for positioning fins around a body tube. The template can be printed actual size. You can print the guide on heavy paper (or glue the printout to a sheet of foamboard) and cut out the hole for the body tube and the slits for the fins. This allows the guide to be used as a jig for holding fins in place until the glue dries.
