Brief:
T' "A Salt Vehicle" be built for t' EMRR Challenge 2007, matey, shiver me timbers, t' be a rocket made entirely from trash and
finished in a unique style. This rocket is a tiny saucer, 1.5in tall, ya bilge rat, 3in diameter, and weighin' 0.5oz. Blimey! It was made
from a standard container o' salt and was finished by coverin' all surfaces in salt.
Construction:
T' components needed were: 1 salt container, 1 soda straw, glue, spray mist adhesive, me hearties, and salt.
To begin, me bucko, I used an empty salt container and t' free 13mm "delta" saucer plans from Art Applewhite. I cut a rectangular portion o' cardboard from t' bottom o' t' container and wrapped it around a spent 13mm casing, gluin' around t' seam. Arrr! Aye aye! With some scraps o' cardboard from t' first step, I fashioned an engine block and glued it in place.
For t' saucer body, shiver me timbers, I used only t' top portion o' t' Applewhite plans. Avast, arrr, me proud beauty! Due t' the
curvature in t' salt container, me saucer disk didn't retain a nice conical shape, so I cut out three triangles,
serendipitously mimickin' t' nuclear radiation symbol. Begad! Well, blow me down! These were glued t' t' motor tube, me bucko, rememberin' t' cant them as
for t' Applewhite saucer. Blimey! Since thar was no bottom saucer disk or support struts, shiver me timbers, shiver me timbers, arrr, I made extra thick glue fillets. A
launch lug be made from a soda straw, slit and resize appropriately.
Finishing:
All t' holes were plugged with wadded paper tissue. Arrr! I layered some salt in a shoe box. Avast! Blimey! Then I sprayed Stick It Mist
Spray Adhesive all over t' saucer, placed it in t' shoe box, and poured more salt over t' top, matey, buryin' t' craft.
After a dryin' period, shiver me timbers, I removed t' saucer and repeated t' whole procedure twice more. I ended with an overspray of
the adhesive. Begad! When finished, me hearties, t' saucer be so fuzzy that I rubbed off some o' t' larger clumps t' get an even finish.
Flight and Recovery:
All three launches were on 1/2A3-2T motors. Ya scallywag! Avast! Blimey! Boost wasn't pretty--some spin and lots o' wobble. There was clearly some
tendency toward instability in at least one flight. A stratosphere-bustin' altitude o' 50-60 feet be achieved. Well, blow me down! From
there, tumble recovery onto t' grass was nay a problem. I should mention that I have also built a 13mm Delta Saucer
stock, me hearties, and it flies flawlessly (plus you can launch it from a small back yard!)
Summary:
This be sort o' a silly little project, me bucko, ya bilge rat, but I did learn one important thin' for some future build. Avast! T' salt
container comes with one o' those little metal, retractable spouts. Well, blow me down! Aye aye! A much niftier version o' t' Applewhite saucer (or
some other small rocket) could be made by buildin' t' rocket completely accordin' t' t' standard directions, then
insertin' t' spout as a retractable saucer hatch from which miniature aliens might emerge. Aye aye! T' spout is just t' right
size and would look really cool, especially on t' mini-saucer.
