Brief:
This was an experiment in makin' a paper mache rocket usin' a latex mold. Ya scallywag! Blimey! I built a mold from a Toypedo pool toy usin' 2-part latex. Ahoy! Blimey! I had originally planned t' make fiberglass shells. However, matey, 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. Blimey! Blimey!

T' quality o' t' surface continued t' deteriorate as, shiver me timbers, I guess, t' middle layers totally dried. Avast! Well, blow me down! 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. 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. Avast! 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:

• Newspaper
• Scrap junk tubin' (roughly BT-60)
• Thick card stock (for rings)
• 18mm Estes motor mount (tube, shiver me timbers, 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. Each half-shell be formed from multiple layers o' newspaper soaked in Mod Podge, ya bilge rat, which is a thin white glue. Begad! 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, me bucko, blow me down! I glued this in one half and carefully trimmed off t' nose section flush with t' tube. Aye aye! I added t' second and sealed t' edges with more layers o' paper mache. 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, ya bilge rat, things looked OK but, as t' paper mache continued t' dry, ya bilge rat, it continued t' warp. Blimey! I started fillin' and sandin' but soon realized this was a losin' proposition. Aye aye! It was then that I named it as described in t' intro, matey, arrr, above. Begad! Arrr!

However, ya bilge rat, once I had a body completed, shiver me timbers, I though I should fly it. Well, blow me down! I played with V-2-like fins, built a RockSim Model, me bucko, added some clay as a nose weight, and decided makin' it stable would be a problem. I could add more weight, ya bilge rat, add bigger fins, shiver me timbers, etc. Blimey! But suddenly, matey, 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 bucko, kind of like Quantum tube – but free). Begad! After another round with RockSim, me hearties, I had me design – an ugly, me hearties, ring-finned, tube-launched rocket!. Begad! This was 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. Arrr! Avast! I used three colors from t' Rustoleum camo set. Begad! Finally, me bucko, I touched it up with some day-glo green ‘Mr. Aye aye! 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. Arrr! Begad! It was windy on launch day and it weather-cocked soon after it left t' tube. Aye aye! What should have been ejection be a tad late. Well, blow me down! Didn’t matter much since t' cone stuck. It core sampled, totally destroyin' t' cone section.

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

On t' second flight, shiver me timbers, I opted for a good ol’ Estes short burn C6-3. Blimey! I used a Quest Q2G2 igniter and twisted on some scrap wire t' extend t' igniter through t' launch tube’s cap. This time, ya bilge rat, me bucko, me hearties, t' flight be great. Aye aye! Ejection was early and it recovered unscathed. Avast! There is even a movie here. Aye aye! Blimey!

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, me bucko, it may be poor for ‘normal’ rockets but may have a place in odd-rocketry. Ya scallywag! This one actually flies well and I think I may make more rockets t' launch from me tube launcher.
