Standard Rocket Assembly Tool™

The Standard Rocket Assembly Tool™ is a fin alignment jig and fixture to bond fins to a rocket body tube. It is also and cradle for filleting fins. The innovative use of magnets allows for fin bracket positioning along any degree around the body tube to accommodate almost any number of fins and a variety of angles for fin placement.

The use of magnets for holding the fins against the alignment bracket allows for infinite combinations of fin shapes, sizes and height without worry of tape residue or unsightly lines from overly strong clips.

Templates for varying fin thicknesses and fin pattern layouts are available for you to print under the Support link at the top of this page. If you do not find a template to fit your need, please feel free to request one by e-mailing design@standardrockets.com and we will work with you to design a template to aid in the construction of your rocket. Template designs are limited to your imagination and we would only need some simple dimensions to meet your needs.

The Standard Rocket Assembly Tool™ can be used for building rockets with swept back fins such as the

16 gauge black zinc plated cold rolled steel base equipped with a bottom mounted weld nut. A 6 inch long threaded rod is then installed into the base weld nut and a nut is used to cinch the rod in place to provide a steady mount for your rocket.
Four 16 gauge black zinc plated cold rolled steel fin alignment brackets. The brackets feature a "cradle top" design to aid in preventing saggy fillets on fin root joints.

Four easy to handle neodynium magnet tacks to hold the rocket fins to the alignment brackets.

A downloadable selection of templates for you to print and use on the baseplate.
Eight neodynium magnet blocks to use to provide lateral force to hold the fins tight against the rocket body tube for those that want that extra bite. You may also use these magnets as guides for the angle brackets along the back edge.
Two pairs of threaded inserts along with brass sleeve bearings for building two motor slugs for use on the threaded rod.
Four circular magnets with countersunk holes with four #5 wood screws. These magnets do not have any set use, they are for your creative use from attaching a magnet to a clothes pin to use for holding your ignitor clips and stopping a dropped clip at the launch pad to making a finger to hold some shape that the magnet tacks will not handle.
