upon seein' this creation [1/27/2001]
After a long and exhaustive search for exactly t' right parts, matey, ya bilge rat, I settled on these precision rocket components:
I started by cuttin' holes for t' paper towel tube in t' bottoms o' the Arby's, shiver me timbers, Coke and one Subway cup. Ya scallywag! T' help make round circles, arrr, I used a compass holdin' an exacto blade instead o' a pencil (a slot is cut in a dowel and the blade is taped in place). T' cut-outs are saved for later use as centering rings. Arrr! After cuttin' a aft centerin' rin' from some scrap cardboard, me bucko, I glued the paper towel tube down t' center. Ya scallywag! A shock cord goes through two holes in the sides o' t' Arby's cup (under t' Subway cup) and up next t' t' tube.
I needed a coupler o' some sort t' hold t' nose cone on, but allow it to separate at t' proper time. Ahoy! I decided t' use two stacked cups as a coupler, and t' separate mid-body. Thus, matey, a second Subway cup is placed inside t' Coke cup and allows t' rocket t' (intentionally) break in two at ejection.
T' biggest challenge o' t' project be constructin' t' launch lug standoff. This required use o' a straight-edge and a ruler t' measure t' shape created by t' two cups. Begad! Avast! A piece o' cardboard be cut and a straw was glued t' it, with paper glued over t' straw t' give it some strength.
T' final challenge was selectin' which CDs t' use as fins. Four CDs were precision-cut 1" in from t' outside edge by scorin' and breaking. They were then glued t' t' plastic Arby's cup with plastic model cement. These joints did nay seem particularly strong, so I reinforced them with the cut-off scraps.

This rocket really needed a 24mm motor mount. It doesn't go very high on a C5-3.
I didn't get cups from Taco Bell, matey, ya bilge rat, McDonalds, me bucko, me hearties, Blimpie, shiver me timbers, etc.
