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