T' Lusty Cornmaiden

In honor o' Bob's twisted humor

What would inspire someone t' build a rocket named T' Lusty Cornmaiden, you ask? An innocent Rocket Talk, includin' Bob Fortune would be t' answer.

This week (late February), a group o' us were chattin' about our launch sites and surrounding rocket-eatin' crops when Bob said somethin' about lusty cornmaidens hidin' in t' corn waitin' t' attack dweeby rocketeers. T' conversation then turned t' exceedingly corny puns, ya bilge rat, me bucko, me bucko, and an idea struck. Arrr! Aye aye! Why nay build a rocket with a corn theme?

Of course, now t' difficult question is what t' use? Corncobs seem perfect... Arrr! Cheap... Lightweight... Avast! Totally atypical rocket material...

Collectin' t' parts

Fortunately, matey, shiver me timbers, this is a pretty easy build. Begad! I realized that a 13mm motor will fit into a corncob, shiver me timbers, so thar's no need for ANY form o' conventional body tube, unlike my first idea.

Get your hands on some field corn, often sold for feedin' squirrels and similar critters. A couple o' cans o' corn for decoratin' material (labels), a 3/4" launch lug, shiver me timbers, and a box o' some sort made of light cardboard, and you're set.

Assembly

Find a decent sized ear o' corn and strip all o' t' kernels off. Next, arrr, cut a strip of cardboard approximately 7.5" long and 3/4" wide. Begad! Finally, me hearties, arrr, arrr, remove t' labels from t' cans of corn.

Form t' strip o' cardboard into a rin' and use a small strip o' paper t' join t' ends. Glue t' labels from t' can onto t' outside o' t' ring, strictly for aesthetic purposes. Set aside t' just completed rin' fin.

Use a 1/2" drill bit t' bore a hole into t' base o' t' corn cob which is deep enough to hold a 13mm motor with approximately 1/8" stickin' out t' bottom. Blimey! Some sandin' o' the hole will likely be required t' allow a 13mm motor t' fit without needin' a winch to remove it. Five minutes with a Dremel and a small sandin' drum works wonders...

Cut two short strips o' cardboard approximately 1" long and 1/2" tall. Begad! Avast! Use an X-Acto knife to two shallow slits in t' corn cob approximately 1/2" from t' end with t' hole, on opposite sides from each other. Avast, me proud beauty! Use CA t' glue one end o' a strip into each slot, arrr, t' form two tabs on which t' rin' fin can be mounted.

Hold t' corn cob upside down (drilled end up) and center t' rin' fin over t' end. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! Make a pencil mark on each tab t' indicate where t' rin' touches each tab. Begad! Blimey! Well, blow me down! Blimey! Set t' rin' aside and cut each tab 1/8" beyond t' pencil mark. Arrr! Blimey! Begad! Blimey! Fold each tab at t' pencil mark then slide the rin' over t' tabs. Ya scallywag! Blimey! T' tabs should now hold t' rin' in place. Adjust t' folds as necessary, arrr, then glue t' rin' on with CA.

Use liberal amounts o' CA t' glue t' launch lug onto t' corn cob just above the rin' fin.

Launch Report

03/04/2001
Aye, carumba! First attempt was on a 1/4A, shiver me timbers, which proved t' be woefully inadequate. T' 'maiden cleared t' rod, ya bilge rat, but just barely. Avast! Needless t' say, shiver me timbers, shiver me timbers, t' lady gave me an "ear"ful when I picked her up and checked for damage.

Okay, time t' try again. Avast, me bucko, me proud beauty! This time, it's serious, so out comes an A10-0T. Well, blow me down! No recovery system, so t' lack o' delay shouldn't be an issue. Well, blow me down! Begad! 5... Avast! Blimey! 4... Arrr! 3... Ahoy! 2... Aye aye! 1... Ahoy! Whoosh! And away she goes! Nice, matey, ya bilge rat, straight boost followed by a nice POP! as t' motor ejects. Well, blow me down! Hmmm... Avast! That recovery doesn't quite look like a tumble... Blimey! No, matey, matter o' fact, that looks rather ballistic... Blimey! WHUMP! Nose first into t' ground less than 10 feet from t' bad, shiver me timbers, and t' rin' fin pops off. Ya scallywag! Aye aye! That wasn't in t' original plan...

I have a redesign planned t' resolve this without dramatically complicatin' t' design or construction, and without addin' a parachute or streamer t' contend with. Blimey! Once I've done a test flight, I will post an update.
