Rocket Fin Marking and Gluing Jig
Description
A jig for aligning and gluing fins and launch lugs onto model rockets. This version is for BT-20 rocket tubes and cardstock fins for rockets such as the Estes Viking. Also can be used to mark the fin and launch lug locations prior to gluing. There are two versions here, one for 3-fins and another for 4-fins. There is also an optional stand to lift the jig up slightly so fins can extend down for gluing. To use: 1) Slide body tube into the jig. 2) Mark the body locations for the fin and also the launch lug. 3) Rotate the body tube in the jig to align the marks with the fin “clips” 4) Optionally tape the lug marking section of the jig to the tube to prevent it from moving. 5) Glue the fins, taking care not to glue the fins to the jig as well as the body tube There is also a generic fin gluing jig. The jig fits into the hole for the engine and can hold three balsa fins for gluing.
