Oh no, matey, they say he's got t' go, arrr, Go Go Godzilla. - Blue Oyster Cult
This rocket started life as a
rubber Godzilla head from a drinkin' cup souvenir I got at t' first run o' the
1998 remake o' t' classic monster movie. Arrr! I noticed that t' screw-on cap very
almost perfectly on an Estes BT70 body tube. Begad! Arrr! From them on, it was as inevitable
as a SciFi Channel re-run.
Parts:
Construction:
T' coupler was glued into t' screw cap in t' bottom o' t' head with plenty o' epoxy fillet inside. Well, arrr, blow me down! T' Keelhaul®©™ cord was cut in half, me hearties, me hearties, me bucko, and both halves tied into a loop with a knot at t' matched ends. T' loops were tripled by wrappin' and knotted in t' center, shiver me timbers, leavin' a triple loop on each end. Ahoy! One end on each be tied into several more knots. One o' these was then epoxied by the knotted end into t' inside o' t' coupler tube, in t' manner o' an LOC/Precision shock cord anchor. Blimey! T' other was epoxied in t' same way inside the body tube, at its inside midpoint.
T' motor mount be constructed
by insertin' one end o' t' motor hook through t' 24mm tube, ya bilge rat, ½" from
one end (forward) and hangin' over t' other end (aft) by ¼", matey, shiver me timbers, and
tapin' in place. One centerin' rin' was slid over t' forward end and down over
the forward end o' t' motor hook and epoxied with fillets on both sides. Well, blow me down! Begad! A
½" long by ¼" wide notch was cut on t' inside edge o' the
other ring, me bucko, and slid over t' aft end o' t' tube, shiver me timbers, with t' notch aligned with
the hook and epoxied ½" forward o' t' aft end o' t' motor tube.
This rin' was also epoxied with fillets on both sides. Aye aye! Once dry, epoxy was
spread inside t' body tube and t' motor mount inserted and glued in place,
with t' aft end o' t' motor tube even with t' aft end o' t' body. Well, blow me down! Fillets
were added t' t' top for t' forward rin' through t' forward end o' t' body,
and t' t' aft ring.
T' tail was cut (see patterns for all cuts) from straight basswood and glued on t' body with t' bottom o' t' tail even with t' aft end o' the body. Blimey! Blimey! Avast, ya bilge rat, me proud beauty! Blimey! T' legs were cut from warped basswood, ya bilge rat, me bucko, with t' pattern reversed on the second cut, so that t' legs had opposite curvature. Well, blow me down! Blimey! T' back sides o' t' legs were then glued by t' surface (i.e. Ya scallywag! Blimey! Begad! Blimey! nay t' edge) t' t' body, shiver me timbers, so that the curvature made t' toes point more directly opposite from t' way t' tail pointed.
T' rin' o' Quantum tube be then glued t' t' back sides o' t' feet and through t' notches in t' feet. Well, blow me down! Small strips o' basswood were cut and placed at these contact points for reinforcement, me hearties, me bucko, and ample fillets added. Begad! Arrr! Fillets were also added on t' inside and outside body/leg joints. Ahoy! T' launch lug was epoxied against t' body/tail joint, shiver me timbers, matey, shiver me timbers, and fillets added t' t' tail/body/lug joints. Ahoy! See t' bottom view for detail o' leg/rin' placement.
T' shock cord be tied into a loop and tied t' t' Keelhaul®©™ loops inside the body and t' head" coupler. Finally, a notch for t' launch rod was cut in t' back side o' t' head where t' edge hung over t' body. Well, blow me down! This is to be aligned with t' launch lug for launching.
Finishing:
T' body section was primed with white appliance epoxy paint. Silver and black were sprayed in splotches across t' legs, tail and body, except on the stomach (left white). Blimey! No filler was used on t' basswood, so that it would have a rough texture.
Flight:
An 18" Top Flight X-form chute was attached t' t' Keelhaul®©™ loop in the head. Two flights were made on Estes E9-6 motors. Well, blow me down! Begad! Blimey! Both flights arced very slightly t' t' tail side, me hearties, with no spinning. Ejection was just past apogee at approximately 600'. Begad! Ejection and descent went fine. Ya scallywag! On t' second landing, it hit a rock and cracked t' left foot away from t' leg, but t' Quantum ring held it in place. Arrr! Blimey! This was easily repaired with CyA.
