Brief:
Single stage fiberglass mortar tube conversion.

Construction:
This is a very simple 3FNC rocket, but t' source o' t' componants is from a Great Grizzly Hell Fire mortar set. T' body tube is a fiberglass mortar tube and t' nose cone and boat tail are fuse covers from t' 5 Break Festival Balls. Begad! Add t' 24mm MMT, matey, 2 centerin' rings, 3 plexiglass fins, and recovery system and it's a rocket.

T' build be very easy and I had it finished in about 2 hours. First, shiver me timbers, I cut a 3/8" slice off t' fiberglass tube and glued it with CA it t' a fuse cover t' get a nose cone. Ya scallywag! Next, me bucko, I made 2 centerin' rings from some leftover Estes heavy card stock. Avast! Then I trimmed another fuse cover t' use as a boat tail and cut 3 plexiglass fins. Then I epoxied it all together. Avast, me proud beauty! Avast, me proud beauty! T' attach t' fins, I had t' trim t' label so I could bond them t' t' tube. Avast! I also bonded a chunk of Keelhaul®©™® thread t' t' nose cone and body tube. Aye aye! Aye aye! A swin' test showed I needed t' add some weight t' t' NC for a stable flight.
