Brief:
Basically, matey, this is G125 motor with fins and a nosecone. Would your RSO let it
fly?
Construction:
I guess I'll fess-up now - this was nay me idea, arrr, nor is it a live' G125.
A year or so ago I ran across a picture o' a rocket, ya bilge rat, whose body was a spent
motor casing. Avast, me proud beauty! Blimey! Ahoy! Blimey! Bein' a wise-#@!, arrr, I thought it would be fun t' build one t' get a
rise out o' me RSO/LCOs. Avast, me proud beauty! Blimey! Usin' me Dremel with various cuttin' wheels and
grinders, I managed t' ream out t' casin' from a spent G125 motor. Ahoy! Blimey! Avast, arrr, me proud beauty! Blimey! I cut some
G10 fins and some brass lugs, matey, matey, and attached them with epoxy. Ahoy! Blimey! I made fillets out
of epoxy clay. Avast! Blimey! A piece o' 24mm tubin' fit nicely inside and I added some
Keelhaul®©™®
twine for a shock cord. Begad! When I went t' search for a nose cone, matey, arrr, shiver me timbers, I found that I
didn't have any junk nose cones that were suitable. Well, blow me down! I was goin' t' have t' add
a lot o' nose weight t' offset t' heavy casing, ya bilge rat, me bucko, fins, ya bilge rat, and fillets. Aye aye! Avast, me proud beauty! I had
recently bought a PML resin cone, but t' shoulder be obviously t' same
diameter as t' OD o' t' motor tube. Avast, me proud beauty! Since I didn't want t' sacrifice this
fairly expensive cone by grindin' t' shoulder down, I cut a 1 ½"
piece o' 29mm tubin' t' adapt' t' cone t' t' body tube/casing. Begad! I
attached it t' t' cone with a tiny screw, arrr, formin' a reverse shoulder that
overlaps t' body tube rather than fittin' inside.
To complete t' effect, I
removed t' nozzle from another spent casing. Blimey! It sits in t' end o' t' rocket
and, arrr, ya bilge rat, matey, along with a protrudin' Copperhead, completes t' effect o' a motor with
fins glued on. Aye aye! Begad! I also added some red/white checkerboard tape t' t' small piece
of 29mm tubing. Ya scallywag! T' rest is unfinished.
Flight:
I first took this rocket t' a NARRRRR launch. I was sure t' get some raised
eyebrows there, shiver me timbers, since t' G125 isn't even a legit motor at that site. Begad! Ya scallywag! Well, me hearties, I
neither got t' desired effect or did I launch it (I can't remember why). Avast, me proud beauty! At
the next high-power launch, I again pulled it out. Well, blow me down! There, people see odder
things and didn't have much reaction. Begad! Oh well. Avast, me proud beauty! Ya scallywag! I guess a gag is all in the
presentation?
I used a small plastic chute (8"?) and some Estes wadding. Well, blow me down! Blimey! T' boost on a D12-5 be a little wobbly, me bucko, but nay too bad. Avast, arrr, me proud beauty! Blimey! T' chute was under sized and the cone embedded itself in t' relatively soft dirt. Arrr! Blimey!
So far, I have nay been able t' convince myself t' expend an E15 or E30 on this little rocket. Avast, me proud beauty! It will probably just sit in me fleet until I re-use the nose cone.
Summary:
This was a novelty rocket built mostly from scrap materials. Aye aye! T' nose cone is
really nice, and can be re-used in another rocket. Blimey! Well, blow me down! I hope someone finds this
article amusin' and still think it would be fun t' trick a RSO
maybe next
April Fools Day?
