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