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