Manufacturer: | Scratch |
Brief:
Basically, this is G125 motor with fins and a nosecone. Aye aye! Blimey! Would your RSO let it
fly?
Construction:
I guess I'll fess-up now - this be nay me idea, shiver me timbers, 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. Blimey! Ahoy! Bein' a wise-#@!, matey, I thought it would be fun t' build one t' get a
rise out o' me RSO/LCOs. Blimey! Aye aye! Usin' me Dremel with various cuttin' wheels and
grinders, I managed t' ream out t' casin' from a spent G125 motor. I cut some
G10 fins and some brass lugs, shiver me timbers, and attached them with epoxy. 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. Ahoy! Blimey! When I went t' search for a nose cone, I found that I
didn't have any junk nose cones that were suitable. Arrr! I was goin' t' have t' add
a lot o' nose weight t' offset t' heavy casing, me bucko, fins, arrr, me hearties, and fillets. Ahoy! I had
recently bought a PML resin cone, but t' shoulder was obviously t' same
diameter as t' OD o' t' motor tube. Well, blow me down! 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. Ahoy! Arrr! 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. It sits in t' end o' t' rocket and, along with a protrudin' Copperhead, 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. Begad! T' rest is unfinished.
Flight:
I first took this rocket t' a NARRRRR launch. Avast! I be sure t' get some raised
eyebrows there, ya bilge rat, since t' G125 isn't even a legit motor at that site. Well, I
neither got t' desired effect or did I launch it (I can't remember why). At
the next high-power launch, arrr, I again pulled it out. Avast, me proud beauty! There, me hearties, me bucko, people see odder
things and didn't have much reaction. Avast, me proud beauty! Oh well. I guess a gag is all in the
presentation?
I used a small plastic chute (8"?) and some Estes wadding. Aye aye! Blimey! T' boost on a D12-5 be a little wobbly, shiver me timbers, arrr, but nay too bad. Ya scallywag! Blimey! T' chute was under sized and the cone embedded itself in t' relatively soft dirt. Ya scallywag! Blimey!
So far, ya bilge rat, I have nay been able t' convince myself t' expend an E15 or E30 on this little rocket. Well, blow me down! Blimey! Avast! Blimey! 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, shiver me timbers, and can be re-used in another rocket. Ahoy! I hope someone finds this
article amusin' and still think it would be fun t' trick a RSO
maybe next
April Fools Day?
