Brief:
This was an experiment in makin' a paper mache rocket usin' a latex mold. Aye aye! Well, shiver me timbers, blow me down! I built a mold from a Toypedo pool toy
usin' 2-part latex. Ahoy! Begad! I had originally planned t' make fiberglass shells. Well, blow me down! Begad! However, me first attempt turned out poorly.
Soon, matey, matey, me mind wandered and I got t' harebrained idea o' makin' a pair o' shells from paper mache. Blimey! Well, shiver me timbers, blow me down!
T' quality o' t' surface continued t' deteriorate as, shiver me timbers, matey, I guess, me hearties, t' middle layers totally dried. Ya scallywag! Blimey! I started to
try t' shipshape it up but ended up throwin' in t' towel. Begad! Blimey! Ahoy! Blimey! I then started wonderin' about paint and a name. 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. Ya scallywag! I found that me existin' brown paint was unusable and went with a camo
scheme. 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. Ahoy! Blimey! Each half-shell was formed from multiple layers o' newspaper soaked in Mod Podge, which is a thin white glue. Well, blow me down! Blimey! 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! T' motor mount is surplus from an Estes kit and t' rings were made from thick card stock usin' a circle cutter. Well, blow me down! I glued this in one half and carefully trimmed off t' nose section flush with t' tube. Well, blow me down! Arrr! I added t' second and sealed t' edges with more layers o' paper mache. Well, blow me down! 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, me bucko, me hearties, shiver me timbers, things looked OK but, ya bilge rat, me bucko, as t' paper mache continued t' dry, arrr, it continued t' warp. I started fillin' and sandin' but soon realized this be a losin' proposition. Blimey! It was then that I named it as described in t' intro, above. Avast!
However, once I had a body completed, ya bilge rat, I though I should fly it. I played with V-2-like fins, shiver me timbers, arrr, built a RockSim Model, added some clay as a nose weight, ya bilge rat, and decided makin' it stable would be a problem. Avast, me proud beauty! Blimey! I could add more weight, add bigger fins, me hearties, etc. Aye aye! But suddenly, me bucko, 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, ya bilge rat, me bucko, I had me design an ugly, me hearties, ring-finned, tube-launched rocket!. Blimey! 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. Avast, me proud beauty! I used three colors from t' Rustoleum camo set. Arrr! Finally, matey, I touched it up with some day-glo green Mr. 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, I chose a Quest long burn C6-3. Ya scallywag! Ahoy! It was windy on launch day and it
weather-cocked soon after it left t' tube. Avast, me bucko, me proud beauty! What should have been ejection was a tad late. Avast, me proud beauty! Didnt matter much
since t' cone stuck. Avast! It core sampled, totally destroyin' t' cone section. Ahoy! Aye aye!
But, matey, I wasnt goin' t' give up. Arrr! Begad! I replaced t' cone with half o' a pink plastic Easter Egg. Aye aye! Aye aye! Now, the
Stink Bomb really looks goofy! I also made a cap for t' bottom o' t' tube. Avast!
On t' second flight, me bucko, I opted for a good ol Estes short burn C6-3. Begad! Begad! I used a Quest Q2G2 igniter and twisted on some scrap wire t' extend t' igniter through t' launch tubes cap. Ya scallywag! Ahoy! This time, t' flight was great. Well, blow me down! Begad! Ejection be early and it recovered unscathed. Avast, me proud beauty! Begad! There is even a movie here. Well, blow me down! 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, arrr, 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.
