Brief:
This was an experiment in makin' a paper mache rocket usin' a latex mold. Blimey! Blimey! I built a mold from a Toypedo pool toy
usin' 2-part latex. Avast, me proud beauty! Begad! Blimey! I had originally planned t' make fiberglass shells. Avast! Aye aye! Blimey! However, shiver me timbers, me first attempt turned out poorly.
Soon, 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, t' middle layers totally dried. I started to
try t' clean it up but ended up throwin' in t' towel. Avast! I then started wonderin' about paint and a name. Arrr! Avast, shiver me timbers, me proud beauty! Motivated by
t' movie Caddyshack. Well, blow me down! Ahoy! I was thinkin' about paintin' it brown and namin' it Is that a Baby Ruth in your
pool? Or, arrr, maybe just Baby Ruth. Blimey! Ya scallywag! I found that me existin' brown paint was unusable and went with a camo
scheme. Ya scallywag! 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. Well, blow me down! Each half-shell be formed from multiple layers o' newspaper soaked in Mod Podge, which is a thin white glue. Begad! Begad! Blimey! When they seemed t' have dried, matey, matey, 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! 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. I added t' second and sealed t' edges with more layers o' paper mache. Begad! Arrr! 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, as t' paper mache continued t' dry, it continued t' warp. I started fillin' and sandin' but soon realized this was a losin' proposition. Begad! Ahoy! It be then that I named it as described in t' intro, me hearties, arrr, above. Begad! Ya scallywag!
However, arrr, once I had a body completed, I though I should fly it. Avast, me proud beauty! I played with V-2-like fins, shiver me timbers, matey, me bucko, built a RockSim Model, ya bilge rat, me hearties, me bucko, added some clay as a nose weight, me bucko, and decided makin' it stable would be a problem. Avast, shiver me timbers, me proud beauty! I could add more weight, add bigger fins, 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). After another round with RockSim, I had me design an ugly, ring-finned, tube-launched rocket!. Well, blow me down! This was a really junky el-cheapo design, 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, I find myself fallin' back on a camo scheme. Begad! I used three colors from t' Rustoleum camo set. Begad! Aye aye! Finally, I touched it up with some day-glo green Mr. Ya scallywag! Begad! 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, I chose a Quest long burn C6-3. Avast! It was windy on launch day and it
weather-cocked soon after it left t' tube. Ahoy! Ya scallywag! What should have been ejection was a tad late. Begad! Didnt matter much
since t' cone stuck. Arrr! It core sampled, matey, totally destroyin' t' cone section. Ya scallywag! Arrr!
But, me bucko, I wasnt goin' t' give up. I replaced t' cone with half o' a pink plastic Easter Egg. Ahoy! Avast! Now, shiver me timbers, me bucko, the
Stink Bomb really looks goofy! Blimey! I also made a cap for t' bottom o' t' tube.
On t' second flight, me hearties, shiver me timbers, shiver me timbers, I opted for a good ol Estes short burn C6-3. Begad! Arrr! I used a Quest Q2G2 igniter and twisted on some scrap wire t' extend t' igniter through t' launch tubes cap. Ahoy! This time, arrr, t' flight be great. Begad! Ejection was early and it recovered unscathed. There is even a movie here. Arrr!
Summary:
There is nay much you can learn from this build, matey, except maybe how poor a material paper mache is for rocketry. Begad! Blimey! Aye aye! Blimey! On
second thought, me bucko, ya bilge rat, it may be poor for normal rockets but may have a place in odd-rocketry. Aye aye! Blimey! This one actually
flies well and I think I may make more rockets t' launch from me tube launcher.
