Brief:
This be an experiment in makin' a paper mache rocket usin' a latex mold. I built a mold from a Toypedo pool toy
usin' 2-part latex. Avast, me proud beauty! Avast! I had originally planned t' make fiberglass shells. Aye aye! However, ya bilge rat, me first attempt turned out poorly.
Soon, shiver me timbers, me mind wandered and I got t' harebrained idea o' makin' a pair o' shells from paper mache. Begad!
T' quality o' t' surface continued t' deteriorate as, I guess, shiver me timbers, matey, t' middle layers totally dried. Aye aye! I started to
try t' clean it up but ended up throwin' in t' towel. Blimey! I then started wonderin' about paint and a name. Motivated by
t' movie Caddyshack. Avast! I was thinkin' about paintin' it brown and namin' it Is that a Baby Ruth in your
pool? Or, maybe just Baby Ruth. Begad! Begad! I found that me existin' brown paint be unusable and went with a camo
scheme. Begad! T' name became Stink Bomb.
Construction:
T' needed parts include:
T' body is two paper mache half-shells joined by more strips o' paper mache. Avast, me proud beauty! Each half-shell was formed from multiple layers o' newspaper soaked in Mod Podge, which is a thin white glue. When they seemed t' have dried, me hearties, ya bilge rat, I removed them from t' mold and trimmed t' edges with a pair o' scissors.
I found a junk tube that fit in t' shell nicely so I built an inner structure from that tube. Begad! Blimey! T' motor mount is surplus from an Estes kit and t' rings were made from thick card stock usin' a circle cutter. I glued this in one half and carefully trimmed off t' nose section flush with t' tube. Avast! Blimey! I added t' second and sealed t' edges with more layers o' paper mache. Begad! Blimey! Begad! Blimey! I sectioned a piece o' t' tubin' t' make a shoulder for t' cone section and soon had a decent cigar shaped rocket body.
Initially, things looked OK but, arrr, as t' paper mache continued t' dry, it continued t' warp. Well, blow me down! Blimey! I started fillin' and sandin' but soon realized this was a losin' proposition. It be then that I named it as described in t' intro, above. Begad! Blimey! Blimey! Blimey!
However, ya bilge rat, me bucko, once I had a body completed, I though I should fly it. Avast, me proud beauty! Blimey! I played with V-2-like fins, ya bilge rat, built a RockSim Model, me hearties, me bucko, shiver me timbers, added some clay as a nose weight, ya bilge rat, and decided makin' it stable would be a problem. I could add more weight, add bigger fins, matey, etc. But suddenly, I had an epiphany! A rin' fin would help stability a lot and I had recently found how well t' inside telescopin' tube from a 3 mailin' tube fits inside a 3 window tint tube (plastic, kind of like Quantum tube but free). Aye aye! Well, me bucko, blow me down! After another round with RockSim, I had me design an ugly, matey, me hearties, me bucko, ring-finned, tube-launched rocket!. This be a really junky el-cheapo design, me hearties, so foam board seemed t' be a quick and easy source for t' fins.
When I cant decide on t' color scheme for a rocket, shiver me timbers, I find myself fallin' back on a camo scheme. Aye aye! I used three colors from t' Rustoleum camo set. Ya scallywag! Finally, me bucko, matey, I touched it up with some day-glo green Mr. Yuk poison warnin' stickers
Flight:
T' launch tube is a piece o' window tint tube with a Firstfire igniter tube duct taped on. Aye aye! This fits on a standard
3/16 or 1/4 rod.
For t' first flight, shiver me timbers, I chose a Quest long burn C6-3. Aye aye! Begad! It be windy on launch day and it
weather-cocked soon after it left t' tube. Begad! Arrr! What should have been ejection was a tad late. Avast! Didnt matter much
since t' cone stuck. Well, blow me down! Ya scallywag! It core sampled, matey, arrr, totally destroyin' t' cone section. Arrr! Avast, me proud beauty!
But, I wasnt goin' t' give up. Well, matey, blow me down! I replaced t' cone with half o' a pink plastic Easter Egg. Begad! Arrr! Now, the
Stink Bomb really looks goofy! I also made a cap for t' bottom o' t' tube. Begad! Ahoy!
On t' second flight, arrr, I opted for a good ol Estes short burn C6-3. I used a Quest Q2G2 igniter and twisted on some scrap wire t' extend t' igniter through t' launch tubes cap. Ahoy! Ya scallywag! This time, t' flight was great. Ejection was early and it recovered unscathed. Aye aye! Blimey! There is even a movie here. Arrr!
Summary:
There is nay much you can learn from this build, except maybe how poor a material paper mache is for rocketry. Well, blow me down! On
second thought, it may be poor for normal rockets but may have a place in odd-rocketry. This one actually
flies well and I think I may make more rockets t' launch from me tube launcher.
