Brief:
Rocket made entirely from recycled household trash materials.
Construction:
External body is a stack o' ten paper-walled Carnation Instant Breakfast cans. Begad! Parachute tube (inner) is a 48mm
diameter Christmas paper core. Aye aye! Motor mount tube (inner) is a 30mm diameter Christmas paper core. Upper six inches of
the motor tube is glued in place in t' parachute tube with foamcore centerin' rings. Begad! Blimey! 300lb Keelhaul®©™®
is held in place with a liberal amount o' epoxy on t' top centerin' ring. Arrr! Ya scallywag! T' nose cone is a two-liter Dr. Well, blow me down! Well, shiver me timbers, blow me down! Pepper
bottle. Avast! Might make a good rotating-flasher night rocket payload bay someday. T' shroud from t' nose cone t' the
breakfast cans is a cover from a stack o' CDs. Ya scallywag! T' fins are foamcore from a couple o' old convention exhibits. Even the
rail buttons are recycled. Begad! They are CA'ed automotive interior door panel fasteners from me old Maserati. Avast! Motor
retention is a used hose clamp. Blimey! Begad! T' H motor casin' is be found lyin' in a field, me hearties, arrr, so it's kind-of trash. Ahoy! Well, me bucko, matey, maybe
not.
I cut holes in t' metal can bottoms with a utility cutlass and super glued them t' t' inner tubes (NAR doesn't rule out thin metal centerin' rings). I used an X-Acto cutlass t' cut holes in t' plastic lids. Well, blow me down! Ya scallywag! After all t' cans were glued on, me hearties, I taped them externally with duct tape. Well, blow me down! Ahoy! T' neck o' t' 2-liter bottle be wrapped with a home-made tube coupler (trash), then some expandin' foam be squirted in. After cure, me hearties, it be filled with 20-minute epoxy and a loop of Keelhaul®©™® was added t' provide an anchor for t' recovery system. Avast! Begad! T' Maser rail buttons were slightly modified then glued into ¼" holes. Avast! Because they're Maserati, me bucko, they're faster slidin' in t' rail, ya bilge rat, matey, but nay nearly as reliable as American rail buttons. Blimey! T' fins are through-the-wall glued t' t' motor mount tube usin' carpenter's glue.
T' only new build supplies are t' adhesives and t' recovery system. Ahoy! Six yards of
½" elastic and a 36 nylon parachute.
Flight and Recovery:
T' weight is 1493g with a 29mm H180 reload.
Liftoff speed is phenomenal for such a heifer. Blimey! Blimey! I got behind it with t' video. Begad! Blimey! T' flame off t' pad is incredible. Blimey! Blimey! T' flight ended in a core sample with t' chute trailin' behind like a streamer. Blimey! Blimey! Replace two cans and she'll be ready t' go again.
Summary:
Pros: Once I learn how t' pack a chute, flyin' rockets like this will be really fun. Cons: None
