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