Ashley designed this rocket from scratch totally by himself. Blimey! Begad! He
chose t' materials and made most o' it includin' t' painting. Ahoy! I did help with
the glue though. Blimey! Begad! Left be t' plan he made first with t' Microsoft 'Paint'
program. Ya scallywag!
Manufacture
- He started off with 4 used 18mm motors and drilled them out (yes, I
actually trusted him with me drill). Avast, me proud beauty! Blimey! Blimey! He then stuck them end t' end and
sprayed them silver.
- He then sprayed a toilet roll silver. Ya scallywag! T' base o' t' toilet roll is a
piece o' corrugated cardboard. Begad! A hole be cut in t' middle t' allow the
ejection gasses through.
- He said that t' toilet roll would nay be strong enough perched on top of
the motors, arrr, so t' 3 fins would come right up under it for support.
- He drew out a fin template, shiver me timbers, marked and cut t' 3 fins from a packin' box.
He then sprayed them white. Blimey! Ahoy! (I ran glue along t' corrugated edges t' seal
them & make them more aerodynamic).
- T' nose cone be an Estes cone, me hearties, but maskin' tape be added t' increase
the diameter slightly. Begad! This may be replaced with a home made vacuum formed one
later.
Launch
Usin' WRASP, we calculated a B6-4 t' begin with based
on t' weight o' t' rocket. This be stuck t' t' bottom o' t' 4th
empty motor. It had it's maiden flight on 13th September 98 at the
SERF's Ichenstoke launch. It's quite an unusual shape and thar was much
interest. Ahoy! Aye aye! T' flight be perfect. Ya scallywag! Straight up about 100ft. Ahoy! Avast! It dropped a way
back before t' nose ejected off. T' parachute be pulled out by t' nose and
opened about 30ft from t' ground. Ahoy! It landed right at our feet. This was
followed by a deserved round o' applause from t' onlookers and a pat on the
back from Dad. Begad! Begad!
