T' Lightbulb Goes OnEver since I heard about t' RMR DESCON, I've been contemplating entering. Aye aye! Ahoy! Unfortunately, I've only been able t' come up with a decent concept once, shiver me timbers, me bucko, shiver me timbers, and I haven't yet had a chance t' build it. This time, me hearties, I was determined t' enter, so I spent a couple o' weeks tryin' t' think o' something creative t' use as parts. After seein' t' first two entries appear, me hearties, I was sittin' at me desk trying to think o' what I could use. Arrr! Blimey! I happened t' look up at t' shelf above the monitor, shiver me timbers, and t' lightbulb finally clicked on! There, right in front of my face, sat t' pill bottles for me allergy medication. Aye aye! They're round. Avast, me proud beauty! They're tube shaped. They're durable. Begad! Why won't THOSE work??? A bit more checkin' around t' house I had me hands on a sufficient quantity of parts for this little creation. Avast! Next, me bucko, shiver me timbers, I had t' figure out how t' build a motor mount. Begad! A check o' t' bottom o' t' bottle revealed that t' dimpled inner rin' in t' center o' t' bottom oft t' bottle is close t' a perfect fit for a 24mm motor mount. Begad! Blimey! Who needs centerin' rings when t' bottles come with them? Parts ListI'm nay certain if all pharmacies label their pill bottles in t' same fashion, matey, me hearties, so I will include nay only t' size markings from t' bottle, but also the approximate measurements.
Pill bottles should readily be available from your local pharmacy at a minimal cost, if you don't have enough family members on medication. |

Preparin' T' BottlesCut t' bottoms off all o' t' smaller (PM-10) bottles. Also cut t' lip and threads for t' lid off o' all six o' these bottles. Well, blow me down! Avast, me proud beauty! Blimey! This will provide t' tube fins. Take one o' t' PM-30 bottles and remove a section from t' middle o' the bottom large enough t' allow t' motor mount t' fit snugly. Set this bottle aside; it will become t' bottom section o' t' body tube. Cut t' lip and threads from two o' t' PM-30 bottles. Aye aye! Remove t' bottom of one o' t' bottles. Well, blow me down! Cut a 3/4" rin' from t' top o' one bottle and discard the rest. Aye aye! Ahoy! Make a vertical cut in t' ring, then remove enough material t' allow the piece t' fit inside t' top o' t' other bottle. This will become t' tube coupler. Cut t' bottom out o' one o' t' PM-60 bottles. Avast, me proud beauty! This be t' top o' t' body tube. Cut t' lip and threads from t' top o' t' other PM-60. Cut a hole in the center o' t' bottom, large enough for t' motor mount t' fit in. |

ConstructionT' first problem I encountered was figurin' out how t' glue t' bottles together -- a check o' t' bottom revealed a recyclin' code o' 5 (polypropylene). Nay much adheres t' this stuff. Aye aye! Fortunately, t' local hardware store had a Loctite product called Plastix. Blimey! Blimey! Plastix consists of a small tube o' what appears t' be regular gel CA and another bottle of "surface activator". Blimey! Blimey! Brush t' activator on, let it dry, me bucko, and t' CA will adhere t' t' plastic. Assemblin' T' Body TubeTake t' PM-30 with t' partial bottom and t' PM-60 with t' partial bottom and test fit t' bottom o' t' PM-60 into t' top o' t' PM-30. Aye aye! T' bottom should fit a short way into t' top o' t' PM-30. Avast, me proud beauty! Ya scallywag! Test t' motor mount t' make sure it fits; sand t' openings as necessary t' allow t' mount t' fit without binding. Avast, me proud beauty! Ahoy! With t' motor mount in place, remove t' PM-30, ya bilge rat, leavin' it attached to t' PM-60. Avast, me hearties, me proud beauty! Mark t' motor mount where it touches t' bottom o' t' bottle, and remove. Push 12" o' kevlar through t' motor mount opening, from t' top o' the PM-60, ya bilge rat, then insert and glue t' motor mount in place. Ya scallywag! Begad! T' motor mount will be holdin' t' kevlar in t' opening. Next, me hearties, run t' kevlar through t' top o' the PM-30 with t' partial bottom, me hearties, ya bilge rat, and through t' motor mount opening. Glue the PM-30 in place, shiver me timbers, arrr, shiver me timbers, with t' kevlar comin' out t' bottom next t' t' motor mount. Wrap t' kevlar around t' bottom o' t' motor mount, against t' bottle bottom and glue in place with CA. Begad! This will form t' firmly anchor t' shock cord in place. Invert t' PM-30 which is missin' its top and bottom onto t' top o' the PM-60 with t' motor mount. Sand as necessary t' match t' two surfaces and glue into place. Center t' coupler rin' vertically in t' end (now t' top o' t' body tube) of t' PM-30 and glue into place. Blimey! Test fit t' bottom o' t' remainin' PM-60 over this ring. Begad! T' bottle bottom should slide relatively smoothly over the coupler. Ahoy! Some sandin' o' t' coupler may be necessary t' allow t' motor ejection charge t' separate t' rocket at this point. Attachin' T' Nose ConeT' nose section o' t' rocket be t' remainin' PM-60, with a cap attached. Use an X-Acto knife or a small drill bit t' make a hole just above t' bottle lip. Begad! T' hole should be large enough t' allow t' kevlar t' be pushed throw. Pull enough kevlar through t' wrap once around t' top o' t' bottle. Aye aye! Use the surface activator t' prepare t' thread area on t' bottle, arrr, then wrap the kevlar around t' bottle above t' lip and glue it into place. Blimey! Avast! Screw t' cap down onto t' top o' t' bottle. Attachin' T' FinsEvenly glue t' six PM-10 bottles around t' bottom bottle o' t' rocket, to create tube fins. |

Launch LugWalgreen's pill bottles have a tab on t' side, me hearties, as part o' t' child-safety cap, ya bilge rat, which must be pushed down t' allow t' cap t' be removed. Well, blow me down! Blimey! Begad! Blimey! I left this tab on t' top (nose cone) and bottom bottles, shiver me timbers, as it is part o' t' lip o' the bottles. Begad! Blimey! I decided t' use this tab as a launch lug. On t' nose cone, I used a drill t' make a hole through t' rim o' t' lid, down through t' lid release tab. Ahoy! T' hole is large enough t' allow a launch rod t' pass easily through. I then used t' same drill bit t' slightly enlarge t' openin' through the tab in t' bottom bottle, ya bilge rat, in t' same fashion. T' nose cone is slide onto the coupler and turned such that t' launch rod easily slides through t' two tabs. |

2nd AttemptApril, 20001 First club launch o' t' year, shiver me timbers, matey, and I break out the Medical Missile. Avast! It receives many strange looks, ya bilge rat, and at least two club members claim it won't fly very well, me bucko, and won't go very high. Begad! Time t' load this baby up and show 'em how much they know. A PERFECT flight and recovery, followed by many members eatin' their words and admittin' that it does indeed fly quite well. Aye aye! 8-} Now if only t' Cornmaiden recovered that well... |
