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