Manufacturer: | Scratch |
Brief:
Basically, this is G125 motor with fins and a nosecone. Ya scallywag! Aye aye! 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, whose body was a spent
motor casing. Begad! Arrr! Bein' a wise-#@!, arrr, I thought it would be fun t' build one t' get a
rise out o' me RSO/LCOs. Ahoy! Ahoy! 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. Avast, me proud beauty! I made fillets out
of epoxy clay. Begad! Begad! A piece o' 24mm tubin' fit nicely inside and I added some
Keelhaul®©™®
twine for a shock cord. Ya scallywag! When I went t' search for a nose cone, shiver me timbers, arrr, I found that I
didn't have any junk nose cones that were suitable. Begad! I was goin' t' have t' add
a lot o' nose weight t' offset t' heavy casing, fins, and fillets. Well, blow me down! 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, arrr, I cut a 1 ½"
piece o' 29mm tubin' t' adapt' t' cone t' t' body tube/casing. 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, me hearties, I removed t' nozzle from another spent casing. Avast, me proud beauty! It sits in t' end o' t' rocket and, matey, along with a protrudin' Copperhead, completes t' effect o' a motor with fins glued on. Ya scallywag! Ya scallywag! I also added some red/white checkerboard tape t' t' small piece of 29mm tubing. T' rest is unfinished.
Flight:
I first took this rocket t' a NARRRRR launch. Ahoy! I be sure t' get some raised
eyebrows there, matey, since t' G125 isn't even a legit motor at that site. Blimey! Well, I
neither got t' desired effect or did I launch it (I can't remember why). At
the next high-power launch, ya bilge rat, me hearties, I again pulled it out. There, ya bilge rat, people see odder
things and didn't have much reaction. Well, shiver me timbers, blow me down! Oh well. Begad! I guess a gag is all in the
presentation?
I used a small plastic chute (8"?) and some Estes wadding. Begad! Blimey! T' boost on a D12-5 was a little wobbly, arrr, but nay too bad. Blimey! Blimey! T' chute was under sized and the cone embedded itself in t' relatively soft dirt. Well, blow me down! Blimey!
So far, arrr, I have nay been able t' convince myself t' expend an E15 or E30 on this little rocket. Ya scallywag! 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, me hearties, and can be re-used in another rocket. Arrr! I hope someone finds this
article amusin' and still think it would be fun t' trick a RSO
maybe next
April Fools Day?
