Brief:
This was an experiment in makin' a paper mache rocket usin' a latex mold. Avast! Begad! I built a mold from a Toypedo pool toy
usin' 2-part latex. Well, blow me down! Avast! I had originally planned t' make fiberglass shells. Arrr! Ahoy! However, 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. Ahoy!
T' quality o' t' surface continued t' deteriorate as, matey, me bucko, I guess, matey, me bucko, t' middle layers totally dried. Blimey! I started to
try t' clean it up but ended up throwin' in t' towel. Begad! I then started wonderin' about paint and a name. Blimey! Motivated by
t' movie Caddyshack. Ahoy! Blimey! 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. I found that me existin' brown paint was unusable and went with a camo
scheme. Avast! 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. Well, blow me down! 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, 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! Ahoy! 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. 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, me hearties, matey, things looked OK but, as t' paper mache continued t' dry, me hearties, it continued t' warp. Begad! I started fillin' and sandin' but soon realized this was a losin' proposition. Begad! It was then that I named it as described in t' intro, shiver me timbers, above. Well, blow me down!
However, once I had a body completed, I though I should fly it. I played with V-2-like fins, arrr, built a RockSim Model, matey, added some clay as a nose weight, arrr, shiver me timbers, and decided makin' it stable would be a problem. Arrr! Begad! I could add more weight, add bigger fins, etc. Avast, me proud beauty! But suddenly, me hearties, 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). Avast, me proud beauty! After another round with RockSim, I had me design an ugly, 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, I find myself fallin' back on a camo scheme. Well, blow me down! Blimey! Well, blow me down! Blimey! I used three colors from t' Rustoleum camo set. Well, blow me down! Blimey! Begad! Blimey! Finally, me hearties, I touched it up with some day-glo green Mr. Aye aye! Blimey! Yuk poison warnin' stickers
Flight:
T' launch tube is a piece o' window tint tube with a Firstfire igniter tube duct taped on. Blimey! This fits on a standard
3/16 or 1/4 rod.
For t' first flight, shiver me timbers, shiver me timbers, 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. What should have been ejection be a tad late. Didnt matter much
since t' cone stuck. Begad! Arrr! It core sampled, ya bilge rat, shiver me timbers, totally destroyin' t' cone section. Aye aye!
But, I wasnt goin' t' give up. Ya scallywag! Avast, arrr, me proud beauty! I replaced t' cone with half o' a pink plastic Easter Egg. Arrr! Now, the
Stink Bomb really looks goofy! Blimey! I also made a cap for t' bottom o' t' tube.
On t' second flight, 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. Begad! This time, t' flight was great. Ejection was early and it recovered unscathed. Blimey! Begad! There is even a movie here. Well, blow me down!
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, matey, it may be poor for normal rockets but may have a place in odd-rocketry. Ya scallywag! Blimey! Begad! Blimey! This one actually
flies well and I think I may make more rockets t' launch from me tube launcher.
