Gone in 60 cc
I was
lookin' over t' descon entries and I saw a lot o' different designs, and I was
wonderin' what I can make into a rocket... Ya scallywag! then I looked at some 60 cc syringe
that a professor gave me, and it's round, its hard, ya bilge rat, and I bet it will fly!
Here's what you need:
- 2 60cc syringe
- some BT-50
- a spent Estes D motor (or any other motor mount o' your choice)
- a CD that no one (includin' yourself) wants. Avast!
- Maskin' tapes
- Keelhaul®©™®
- Streamers
- Take a 60 cc syringe and saw off either end, matey, arrr, this will be your bottom
section. Avast, me proud beauty!
- Take t' other 60 cc syringe and saw off t' plunger end, then measure
about .75 inch from t' end where t' needle goes, me hearties, and cut that off. Save the
"nosecone"
- Glue a BT-50 with some tape wrapped around it into t' "nosecone"
to make a shoulder. Begad! Ya scallywag! T' BT-50 will have a very loose fit in t' 60cc syringe so
you need t' widen t' tube with maskin' tape in order t' glue it. Begad! I used epoxy
and it works fine. Avast!
- Use another BT-50 t' join both syringes together. Aye aye! Begad!
- Glue a BT-50 t' length o' a D motor t' t' bottom o' t' syringe, arrr, this
will be your motor mount. Begad! Blimey! Now you can decide whether or nay t' use 18mm mounts.
If you want t' use 18mm mounts, me bucko, either glue in a spent D motor, or glue in a
motor mount for 18mm motors, but before you do that, thread some Keelhaul®©™® through
the BT-50 and tie a knot at t' bottom end. Well, blow me down! Begad! Then glue t' motor mount in, the
Keelhaul®©™® will be your shock cord.
- Cut a CD into whatever shape you want (I just cut it into 4 pieces and glue
3 o' t' piece into t' syringe with CA followed by epoxy fillets)
- Add streamer and t' right amount o' nose weight. You need quite a bit
because t' syringe is a little heavy.... Ahoy!
I need t' add a flight report.... Blimey! I flew me gone in 60cc Saturday on a A8-3,
and t' rocket just sizzled on t' pad.... Well, blow me down! Ya scallywag! apparently it was too heavy, shiver me timbers, then
the ejection charge popped and charred t' inside o' t' rocket and broke a
fin... so it's retired...
