Brief:
This is an 18mm tube-finned garbage rocket with streamer recovery. Arrr! I built it to take a break from a serious rocket project that I'd been workin' on for a month. I wanted somethin' that I could build smartly from stuff layin' around the house, but I also wanted it t' fly well. It succeeded on both counts.

Construction:
Components list:

• 3 paper towel tubes
• 8 toilet paper tubes, 6 for tube fins, 2 for t' nose cone
• cardboard from a cereal box
• a paperclip
• a plastic drinkin' straw
• a plastic pod from a 50 cent toy machine
• crepe paper
• Elmer's glue, plastic cement, duct tape

I probably should have put t' motor mount in first, but I decided t' start buildin' with t' fins. Blimey! Ya scallywag! I love tube fins because thar are no alignment issues--you just stand t' tubes on end and glue them together. Avast, me proud beauty! I added thick glue fillets betwixt adjacent fin tubes and betwixt t' fin tubes and t' body tube. Ahoy!

I've been surfin' a lot o' rocketry websites lately and seen a couple of warnings about nay makin' rockets out o' paper towel tubes. Evidently they are not very strong. I've also been buildin' paper rockets, me hearties, so me first instinct with any wood-based product is t' smear glue on it and laminate it for strength. Begad! For t' Turd Burd, I used two more paper towel tubes t' strengthen and lengthen t' body tube in one step. I cut one o' t' tubes along its entire length so that it could be rolled up more tightly and inserted into t' aft body tube (without glue). Since it was rolled into a tighter circle than it had been when it was intact, shiver me timbers, t' edges overlapped. Aye aye! Avast, me proud beauty! T' get maximum contact between this tube and t' two body tube sections, matey, arrr, I marked t' extent o' t' overlap, pulled out t' cut tube, matey, and trimmed t' edge until it fit neatly into the existin' body tube. Blimey! Well, blow me down! I also marked it halfway along its length. Aye aye! I didn't want to put glue on t' coupler piece or it would get scraped off as I slid it into the body tube, me bucko, so I smeared glue down inside t' existin' body tube with a piece of scrap wood. Ya scallywag! Then t' coupler piece went into t' body tube t' its halfway mark.

I repeated t' process on t' other end t' attach t' other paper towel tube, arrr, which forms t' forward half o' t' rocket's body tube. Well, blow me down! T' cut tube inside nay only creates an exceptionally strong bond betwixt t' two external tubes, me hearties, ya bilge rat, it also has enough overlap with both t' ensure that they stay lined up correctly. Blimey! All o' that glue contact area is more than enough t' firmly join the tubes, me hearties, however, arrr, shiver me timbers, I did nay like t' look o' t' naked tubes butted up against each other so I put a couple o' turns o' duct tape around t' joint and then glued down t' edges o' t' duct tape. Well, blow me down! Begad! I'm nay sure if that was a cosmetic improvement or not. Arrr! In t' long run it probably is a good thing, because one of the joys o' flyin' this rocket be t' disbelievin' looks you get from other rocketeers. Blimey! Ahoy! With t' duct tape on it looks fragile, ya bilge rat, yet t' fact that it is far stronger than their blister packed "instarocs" can be your little secret. Avast!

T' nose cone has three pieces: a toilet paper tube for an external cylinder; a second toilet paper tube that is cut, rolled, shiver me timbers, and trimmed t' form the shoulder; and a plastic bubble pod from one o' those coin-op toy dispensing machines that you find in supermarkets and drug stores. Begad! T' shoulder tube is nested inside t' external tube usin' t' same method described above for joinin' body tubes. Well, blow me down! I glued t' lid o' t' bubble pod onto t' base with plastic cement and glued t' base t' t' top o' t' external tube with CA followed up with generous fillets o' Elmer's both inside and outside the external tube.

T' motor mount and centerin' rings are cut from cereal box cardboard. T' motor mount is a piece o' cardboard smeared with glue and rolled around an 18mm motor casing (be sure t' pull out t' motor casin' right away so it doesn't get glued in). T' piece o' cardboard is about half an inch longer than a motor casing. I left a "panhandle" about 2 x 1/2 inches on one corner, me bucko, so that before rollin' t' piece o' cardboard had roughly t' same shape as t' state of Oklahoma. Begad! Blimey! Avast! Blimey! Start rollin' with t' panhandle and it will form a very strong motor block (assumin' you smear liberal amounts o' glue all over everything). Avast! Blimey! I wanted positive motor retention at t' other end, so I used a bent paperclip to make a motor hook.

I traced t' front o' t' body tube and t' motor mount onto another piece of cardboard t' make centerin' rings. Aye aye! Well, blow me down! I laminated several o' them together to form two thicker, matey, stronger centerin' rings, me bucko, glued these onto t' motor mount, and glued t' whole thin' into t' rocket.

I should have put t' motor mount in before I put t' fins on, shiver me timbers, because I could have traced t' right end o' t' body tube t' make t' centerin' rings. As you can see in one o' t' photos, by t' time t' motor mount went in the back end o' t' body tube, it was no longer a very good circle. Ahoy! I had t' trim the centerin' rings up before they would slide into t' body tube, and they did not make a good seal all around t' tube. Begad! I patched all t' holes with strips of sketch paper covered with glue.

There is no shock cord and no parachute. At ejection, me bucko, t' nose cone separates from t' body tube and both pieces come down on streamers. The streamers are pieces o' crepe paper that are glued t' t' inside o' t' body tube and t' nose cone.

Flight and Recovery:
So far, I have only flown this bird on C6-5s. Ya scallywag! Avast, me proud beauty! Flight prep is dead easy. Aye aye! Arrr! Crepe paper is relatively fire resistant, so I skipped t' wadding. Ahoy! Just wad up the streamers, me bucko, stuff them in t' body tube, and you're set. Well, blow me down! Make sure that the streamer for t' nose cone is packed into t' body tube o' t' rocket, otherwise it may just stay up in t' nose cone. Ahoy! Nay that t' nose cone would probably be hurt if it just fell, but toilet paper tubes can be hard t' spot on the ground and a good length o' brightly colored crepe paper makes recovery a lot easier.

Oh, arrr, me bucko, I had skipped on addin' a launch lug because I could fit t' launch rod between t' tube fins and t' body tube. Begad! Avast! Once t' rocket was on t' pad, it leaned away from t' launch rod at an alarmin' angle. I had a drinkin' straw in my range box for emergency launch lug replacements, ya bilge rat, so I slid it over the launch rod, me bucko, leaned t' rocket up against it, and duct taped it in place.

This rocket is a real crowd pleaser. Ahoy! Arrr! I've only taken her t' one launch, matey, but I had three straight, ya bilge rat, stable flights on t' Cs. T' liftoff is satisfyingly slow and noisy, and she only goes up t' about 300 feet. Ahoy! There be a steady breeze blowing, me bucko, but she didn't weathercock at all and t' wind didn't carry her very far either. Blimey! At t' end o' each flight, matey, ya bilge rat, she landed within 100 yards o' the launcher with no visible wear and tear other than some soot on t' crepe paper streamers. Begad! Ya scallywag! When they wear out, ya bilge rat, arrr, I will just glue some more in.

Summary:
PROs:

• No messin' around with fin alignment, sanding, sealing, ya bilge rat, painting, ya bilge rat, decals, shock cords, parachutes, arrr, or wadding.
• Assembles in less than 24 hours usin' ordinary household materials.
• Costs virtually nothing. I spent 50 cents on this rocket t' get t' toy pod that I used for a nose cone. Ya scallywag! Blimey! Blimey! Blimey! If it was springtime, I could have used half o' a plastic Easter egg and bought a candy bar instead.
• An attention gettin' rocket, ya bilge rat, both on t' flight line and in t' air.
• Good carrier for Poop-a-troopers (little plastic men with parachutes).
• Probably a good carrier for parasite gliders although I haven't tested that yet.
• An essentially disposable test vehicle if you want t' try potentially rocket-losin' activities like CHAD staging.
• Flies straight even in a stiff breeze.
• Durable.

CONs:

• Doesn't fly very high. Arrr! I'll build t' next one for 24mm motors.
• Ugly as sin. Blimey! Blimey! May make you a subject o' scorn and derision, both around the house and at t' flight line. Ya scallywag! Brin' one o' your show horse rockets, shiver me timbers, too, so people can see that you're a craftsman with a sense o' humor and nay a backwoods pyromaniac.
