First purchase CLOSURE SET includes nozzle holder end closure, delay
holder end closure, spare o-rings, instructions. All other parts are separate components for replacement or special applications. Nozzle closure has positive seal in two places and recommended nozzle (included in reload packs) is reuseable at least three times. Bulkhead closure has positive seal in two places and standard friction fit delay element with expendable o-ring seal. Closure accepts small quantities of ejection powder in the well and 1/4g to 3/8g is recommended for MR and LMR respectively. 1/2g is recommended for typical HPR rockets. Liner ejection tool (wood dowel) aids removal of paper liners which have been damaged by long duration propellant loads thus protecting the valuable casing system. Extra o-rings are included for replacement as they become damaged during normal usage. In particular the nozzle o-ring can be damaged by installation of nozzles so bevel the nozzle edge slightly with sandpaper to increase seal life. Grain count is nominal. Longer motors use fewer double length grains (6 grain 720 uses 3 double length grains). | |||

Closure has positive seal in one place and standard friction fit delay element. Closure accepts small quantities of ejection powder in the well and 1/4g to 3/8g is recommended. Delay needs to be a tight (interference) fit. If loose add a FLAT layer of clear tape to the outside surface until it is a tight fit. Closure edge is slightly beveled to allow insertion and the delay should be a clean smooth edge. Debur the end circumference as needed by rubbing on a smooth surface such as glass. | ||
