Brief:
Basically, this is G125 motor with fins and a nosecone. Begad! Blimey! 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 was a spent
motor casing. Begad! Bein' a wise-#@!, I thought it would be fun t' build one t' get a
rise out o' me RSO/LCOs. Begad! Usin' me Dremel with various cuttin' wheels and
grinders, ya bilge rat, I managed t' ream out t' casin' from a spent G125 motor. I cut some
G10 fins and some brass lugs, matey, and attached them with epoxy. Avast! Ya scallywag! I made fillets out
of epoxy clay. A piece o' 24mm tubin' fit nicely inside and I added some
Keelhaul®©™®
twine for a shock cord. Aye aye! When I went t' search for a nose cone, I found that I
didn't have any junk nose cones that were suitable. I be goin' t' have t' add
a lot o' nose weight t' offset t' heavy casing, me hearties, fins, and fillets. I had
recently bought a PML resin cone, ya bilge rat, ya bilge rat, but t' shoulder was obviously t' same
diameter as t' OD o' t' motor tube. Ahoy! 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, formin' a reverse shoulder that
overlaps t' body tube rather than fittin' inside.
To complete t' effect, matey, I
removed t' nozzle from another spent casing. Begad! Blimey! It sits in t' end o' t' rocket
and, along with a protrudin' Copperhead, ya bilge rat, completes t' effect o' a motor with
fins glued on. I also added some red/white checkerboard tape t' t' small piece
of 29mm tubing. Blimey! Blimey! Avast, me proud beauty! Blimey! T' rest is unfinished.
Flight:
I first took this rocket t' a NARRRRR launch. Arrr! I was 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). Begad! At
the next high-power launch, matey, matey, I again pulled it out. There, me bucko, people see odder
things and didn't have much reaction. Begad! Aye aye! Oh well. Begad! Well, blow me down! I guess a gag is all in the
presentation?
I used a small plastic chute (8"?) and some Estes wadding. Avast, me proud beauty! T' boost on a D12-5 was a little wobbly, arrr, ya bilge rat, but nay too bad. Avast, me proud beauty! Aye aye! T' chute was under sized and the cone embedded itself in t' relatively soft dirt. Begad!
So far, matey, I have nay been able t' convince myself t' expend an E15 or E30 on this little rocket. 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. Begad! T' nose cone is
really nice, and can be re-used in another rocket. Avast, me proud beauty! Avast, me hearties, me proud beauty! I hope someone finds this
article amusin' and still think it would be fun t' trick a RSO
maybe next
April Fools Day?
