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