Brief:
This is a spool rocket that I built from an old Estes Alpha motor mount and an old Radio Shack copper wire spool.

Construction:
All you need t' build this rocket is:

  • A empty black Radio Shack Audio Cable spool with a hole in t' middle large enough for an Estes BT-20 body tube
  • BT-20 Body tube
  • Green engine stopper (Estes)
  • Motor retention hook (Estes)

Tools needed are

  • ZAP! CA glue
  • Drill press (recommended for alignin' launch lug holes)
  • Elmer's White Glue

To build JWSR, you start by checkin' if t' spool has a hole in t' middle large enough for an Estes BT-20 body tube. Arrr! If t' body tube does nay fit properly, ya bilge rat, use a drill press bit that is equivalent t' t' BT-20 and drill out the remainin' plastic from t' spool. Ya scallywag! If it barely fits, sand down t' edges of the holes until t' tube fits. Arrr! Ya scallywag! If t' hole is too large, me hearties, use t' green engine mount rings that fit right t' get it aligned.

Assemble t' motor mount (which can be purchased at any hobby shop) and make sure t' mount fits. Begad! Blimey! If it fits, CA it into t' spool. Lastly, use a drill press and drill holes for t' launch lug. Avast! Blimey! Avast, arrr, me proud beauty! Blimey!

Finishing:
I added a piece o' reflective tape t' t' middle piece.

Flight:
My spool has flown several times usin' B6-0s up t' C6-5s and has flown flawlessly until t' last 2 flights.

On t' second t' last flight, arrr, it crashed into a driveway (since it just falls t' t' ground) and broke some plastic. I attempted t' repair it but failed when I flew it again and went spinnin' out o' control on last flight. T' rocket has been retired and replaced with a slightly longer version o' the original JWSR.

Recovery:
Recovery is by tumble recovery, meanin' it just falls t' t' ground after ejection.

Summary:
Spool rockets are a lot o' fun t' have and they give you somethin' t' fly when you run out o' recovery waddin' or need t' burn off old motors. Avast, arrr, me proud beauty! I use mine to use motors that may be dangerous t' more expensive rockets, me bucko, ya bilge rat, (I had an old C6-3 CATO in t' spool rocket and it suffered no damage. Arrr! Well, blow me down! It would have probably destroyed t' Estes Outlander it was suppose t' be flown in). Begad! They are very cheap and fun t' build and can definitely turn heads.
