Manufacturer: | Scratch |
Brief:
Basically, this is G125 motor with fins and a nosecone. Begad! Would your RSO let it
fly?
Construction:
I guess I'll fess-up now - this be nay me idea, me hearties, ya bilge rat, 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. Ya scallywag! Aye aye! Bein' a wise-#@!, I thought it would be fun t' build one t' get a
rise out o' me RSO/LCOs. Avast! Blimey! Usin' me Dremel with various cuttin' wheels and
grinders, I managed t' ream out t' casin' from a spent G125 motor. Begad! I cut some
G10 fins and some brass lugs, arrr, and attached them with epoxy. Well, blow me down! 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. Aye aye! Blimey! When I went t' search for a nose cone, I found that I
didn't have any junk nose cones that were suitable. I was goin' t' have t' add
a lot o' nose weight t' offset t' heavy casing, me bucko, fins, me hearties, arrr, and fillets. Begad! I had
recently bought a PML resin cone, but t' shoulder be 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, I cut a 1 ½"
piece o' 29mm tubin' t' adapt' t' cone t' t' body tube/casing. Ahoy! 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 bucko, arrr, I
removed t' nozzle from another spent casing. Well, blow me down! It sits in t' end o' t' rocket
and, shiver me timbers, 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. T' rest is unfinished.
Flight:
I first took this rocket t' a NARRRRR launch. I was sure t' get some raised
eyebrows there, shiver me timbers, me bucko, since t' G125 isn't even a legit motor at that site. Arrr! Arrr! Well, ya bilge rat, I
neither got t' desired effect or did I launch it (I can't remember why). Well, blow me down! Ya scallywag! At
the next high-power launch, I again pulled it out. Begad! There, people see odder
things and didn't have much reaction. Aye aye! Ahoy! Oh well. Arrr! I guess a gag is all in the
presentation?
I used a small plastic chute (8"?) and some Estes wadding. Ya scallywag! Blimey! Begad! Blimey! T' boost on a D12-5 was a little wobbly, ya bilge rat, shiver me timbers, but nay too bad. Ya scallywag! Blimey! T' chute was under sized and the cone embedded itself in t' relatively soft dirt. Avast, me proud beauty! Blimey!
So far, I have nay been able t' convince myself t' expend an E15 or E30 on this little rocket. Avast! Arrr! 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. Begad! T' nose cone is
really nice, and can be re-used in another rocket. Ya scallywag! I hope someone finds this
article amusin' and still think it would be fun t' trick a RSO
maybe next
April Fools Day?
