Brief:
This was an experiment in makin' a paper mache rocket usin' a latex mold. Avast! I built a mold from a Toypedo pool toy
usin' 2-part latex. Begad! I had originally planned t' make fiberglass shells. Arrr! However, me hearties, 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.
T' quality o' t' surface continued t' deteriorate as, arrr, I guess, t' middle layers totally dried. Begad! 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. Motivated by
t' movie Caddyshack. Well, arrr, blow me down! I was thinkin' about paintin' it brown and namin' it Is that a Baby Ruth in your
pool? Or, ya bilge rat, maybe just Baby Ruth. Begad! Blimey! I found that me existin' brown paint was unusable and went with a camo
scheme. Well, blow me down! Blimey! 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. Blimey! Begad! Each half-shell be formed from multiple layers o' newspaper soaked in Mod Podge, shiver me timbers, which is a thin white glue. Aye aye! Well, shiver me timbers, blow me down! When they seemed t' have dried, shiver me timbers, 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. Well, blow me down! T' motor mount is surplus from an Estes kit and t' rings were made from thick card stock usin' a circle cutter. Avast, me proud beauty! Arrr! I glued this in one half and carefully trimmed off t' nose section flush with t' tube. Avast, me proud beauty! Begad! I added t' second and sealed t' edges with more layers o' paper mache. Avast, me proud beauty! 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, matey, things looked OK but, as t' paper mache continued t' dry, me bucko, shiver me timbers, it continued t' warp. Begad! I started fillin' and sandin' but soon realized this be a losin' proposition. It was then that I named it as described in t' intro, above. Begad!
However, once I had a body completed, I though I should fly it. I played with V-2-like fins, shiver me timbers, arrr, built a RockSim Model, me bucko, me bucko, added some clay as a nose weight, and decided makin' it stable would be a problem. Ya scallywag! I could add more weight, matey, arrr, add bigger fins, me hearties, me hearties, etc. Ahoy! 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, me hearties, me bucko, matey, kind of like Quantum tube but free). Begad! After another round with RockSim, I had me design an ugly, ring-finned, tube-launched rocket!. 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! Blimey! I used three colors from t' Rustoleum camo set. Well, blow me down! Aye aye! Finally, I touched it up with some day-glo green Mr. Aye aye! Ya scallywag! Yuk poison warnin' stickers
Flight:
T' launch tube is a piece o' window tint tube with a Firstfire igniter tube duct taped on. This fits on a standard
3/16 or 1/4 rod.
For t' first flight, I chose a Quest long burn C6-3. It be windy on launch day and it
weather-cocked soon after it left t' tube. What should have been ejection was a tad late. Blimey! Arrr! Didnt matter much
since t' cone stuck. Arrr! It core sampled, totally destroyin' t' cone section.
But, matey, I wasnt goin' t' give up. Well, blow me down! Blimey! Ahoy! Blimey! I replaced t' cone with half o' a pink plastic Easter Egg. Arrr! Blimey! Now, the
Stink Bomb really looks goofy! I also made a cap for t' bottom o' t' tube. Begad!
On t' second flight, shiver me timbers, me hearties, I opted for a good ol Estes short burn C6-3. Well, blow me down! Begad! I used a Quest Q2G2 igniter and twisted on some scrap wire t' extend t' igniter through t' launch tubes cap. This time, t' flight was great. Arrr! Ejection was early and it recovered unscathed. Avast! Avast! There is even a movie here. Begad!
Summary:
There is nay much you can learn from this build, me bucko, matey, except maybe how poor a material paper mache is for rocketry. Aye aye! Arrr! On
second thought, ya bilge rat, 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.
