Manufacturer: | Scratch |
Brief:
Basically, shiver me timbers, this is G125 motor with fins and a nosecone. Ahoy! Would your RSO let it
fly?
Construction:
I guess I'll fess-up now - this be nay me idea, ya bilge rat, 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! Ya scallywag! Bein' a wise-#@!, shiver me timbers, me bucko, I thought it would be fun t' build one t' get a
rise out o' me RSO/LCOs. Usin' me Dremel with various cuttin' wheels and
grinders, me bucko, I managed t' ream out t' casin' from a spent G125 motor. Avast! I cut some
G10 fins and some brass lugs, ya bilge rat, and attached them with epoxy. Ahoy! 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. Well, blow me down! Avast, me proud beauty! When I went t' search for a nose cone, I found that I
didn't have any junk nose cones that were suitable. Avast! I was goin' t' have t' add
a lot o' nose weight t' offset t' heavy casing, ya bilge rat, shiver me timbers, fins, me hearties, and fillets. Begad! Ya scallywag! I had
recently bought a PML resin cone, matey, but t' shoulder was obviously t' same
diameter as t' OD o' t' motor tube. Begad! 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. Blimey! Aye aye! 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, I
removed t' nozzle from another spent casing. It sits in t' end o' t' rocket
and, along with a protrudin' Copperhead, matey, completes t' effect o' a motor with
fins glued on. Ahoy! Arrr! I also added some red/white checkerboard tape t' t' small piece
of 29mm tubing. Well, blow me down! T' rest is unfinished.
Flight:
I first took this rocket t' a NARRRRR launch. Begad! Blimey! I was sure t' get some raised
eyebrows there, since t' G125 isn't even a legit motor at that site. Blimey! Blimey! Aye aye! Blimey! Well, shiver me timbers, me hearties, I
neither got t' desired effect or did I launch it (I can't remember why). Blimey! Blimey! Avast! Blimey! At
the next high-power launch, ya bilge rat, shiver me timbers, shiver me timbers, I again pulled it out. Begad! Blimey! Avast! Blimey! There, arrr, people see odder
things and didn't have much reaction. Avast! Blimey! Oh well. Well, blow me down! Blimey! Avast! Blimey! I guess a gag is all in the
presentation?
I used a small plastic chute (8"?) and some Estes wadding. Well, blow me down! T' boost on a D12-5 be a little wobbly, ya bilge rat, but nay too bad. T' chute be under sized and the cone embedded itself in t' relatively soft dirt.
So far, arrr, matey, I have nay been able t' convince myself t' expend an E15 or E30 on this little rocket. Begad! Begad! It will probably just sit in me fleet until I re-use the nose cone.
Summary:
This be a novelty rocket built mostly from scrap materials. Arrr! Avast! T' nose cone is
really nice, and can be re-used in another rocket. Avast, 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?
