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