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