Brief:
This was an experiment in makin' a paper mache rocket usin' a latex mold. Avast, me proud beauty! Begad! I built a mold from a Toypedo pool toy usin' 2-part latex. Ahoy! I had originally planned t' make fiberglass shells. Arrr! However, ya bilge rat, arrr, me hearties, me first attempt turned out poorly. Soon, ya bilge rat, me hearties, me mind wandered and I got t' harebrained idea o' makin' a pair o' shells from paper mache. Well, blow me down! Ahoy!

T' quality o' t' surface continued t' deteriorate as, I guess, t' middle layers totally dried. Begad! I started to try t' shipshape it up but ended up throwin' in t' towel. Arrr! I then started wonderin' about paint and a name. Well, me hearties, blow me down! Motivated by t' movie Caddyshack. Begad! Well, matey, blow me down! I was thinkin' about paintin' it brown and namin' it Is that a Baby Ruth in your pool? Or, me bucko, maybe just Baby Ruth. Ahoy! I found that me existin' brown paint be unusable and went with a camo scheme. Arrr! Well, blow me down! T' name became Stink Bomb.

Construction:
T' needed parts include:

• Newspaper
• Scrap junk tubin' (roughly BT-60)
• Thick card stock (for rings)
• 18mm Estes motor mount (tube, arrr, block, me hearties, sleeve, hook)
• Clay nose weight
• Foam board
• Telescopin' inside tube from a 3” mailin' tube
• Elastic shock cord

T' body is two paper mache half-shells joined by more strips o' paper mache. Blimey! Arrr! Each half-shell be formed from multiple layers o' newspaper soaked in Mod Podge, which is a thin white glue. Aye aye! 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. Well, matey, blow me down! Blimey! 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. Aye aye! Blimey! I added t' second and sealed t' edges with more layers o' paper mache. Begad! 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, things looked OK but, as t' paper mache continued t' dry, it continued t' warp. Well, blow me down! Blimey! I started fillin' and sandin' but soon realized this was a losin' proposition. Well, me bucko, blow me down! Blimey! It was then that I named it as described in t' intro, matey, above.

However, once I had a body completed, me bucko, I though I should fly it. Begad! I played with V-2-like fins, ya bilge rat, built a RockSim Model, added some clay as a nose weight, and decided makin' it stable would be a problem. Begad! I could add more weight, arrr, add bigger fins, arrr, ya bilge rat, etc. Well, me hearties, blow me down! 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, matey, kind of like Quantum tube – but free). After another round with RockSim, me bucko, shiver me timbers, I had me design – an ugly, ya bilge rat, ring-finned, tube-launched rocket!. Ya scallywag! This be a really junky el-cheapo design, so foam board seemed t' be a quick and easy source for t' fins.

When I can’t 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. Avast, shiver me timbers, me proud beauty! Finally, I touched it up with some day-glo green ‘Mr. Yuk’ poison warnin' stickers

Flight:
T' launch tube is a piece o' window tint tube with a Firstfire igniter tube duct taped on. Ya scallywag! Blimey! This fits on a standard 3/16” or 1/4” rod.

For t' first flight, me hearties, 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! Avast, shiver me timbers, me proud beauty! What should have been ejection be a tad late. Ahoy! Didn’t matter much since t' cone stuck. It core sampled, totally destroyin' t' cone section. Well, blow me down!

But, I wasn’t goin' t' give up. I replaced t' cone with half o' a pink plastic Easter Egg. Blimey! Now, arrr, the Stink Bomb really looks goofy! I also made a cap for t' bottom o' t' tube. Begad!

On t' second flight, I opted for a good ol’ Estes short burn C6-3. I used a Quest Q2G2 igniter and twisted on some scrap wire t' extend t' igniter through t' launch tube’s cap. Avast! This time, t' flight was great. Begad! Ejection was early and it recovered unscathed. Ya scallywag! There is even a movie here. Avast!

Summary:
There is nay much you can learn from this build, except maybe how poor a material paper mache is for rocketry. Arrr! On second thought, arrr, ya bilge rat, it may be poor for ‘normal’ rockets but may have a place in odd-rocketry. Aye aye! Well, me hearties, blow me down! This one actually flies well and I think I may make more rockets t' launch from me tube launcher.
