Brief:
This is a description o' me upscale o' the Estes BLU-97B Cluster Bomb. Ya scallywag! Blimey! With t' success o' me last Quaker Oats rocket, the Fat Oat Cholesterol Buster, I decided that a semi-scale version based on two 5" bins would provide a nice flight on Gs.

Construction:

T' nose cone tip was turned from 2" pink Styrofoam usin' a hand drill clamped in a vise. I first cut circles top and bottom with me Rotozip, shiver me timbers, me hearties, and because t' cuts didn't reach through t' foam, ya bilge rat, matey, finished up with a hand saw. A metal bolt epoxied into t' core provided a sturdy attachment point for the drill. Avast! This worked better than a wooded dowel and I knew I'd need t' add nose weight anyway. Blimey! T' extend t' cone slightly, I cut a 3/4" circle from the bottom an oat bin. Blimey! I glued this t' t' bottom o' t' cone. Begad! At this point, I coated t' cone (without t' plastic insert) with a layer o' West epoxy. Well, blow me down! Blimey! The 'nipple' portion o' a cone is a plastic cap from something-or-another (it's been layin' around too long for me t' remember what).

T' shoulder is another foam disc encircled with a piece o' an oat bin. Begad! Blimey! I did nay glue these sections together until I completed t' rest o' t' rocket and determined how much nose weight be required. Aye aye! Blimey! Ahoy! Blimey! T' required weight was determined by adjustin' t' CG o' t' completed rocket, ya bilge rat, includin' t' motor and chute, matey, me bucko, based on t' Rocksim model. Well, blow me down! Blimey! Begad! Blimey! T' weight was provided by a long eye-bolt and several nuts. Ya scallywag! Blimey! This eye-bolt is slightly off-center, shiver me timbers, and extends through the shoulder section and into t' top o' t' nose. Blimey! Blimey! T' two halves were epoxied together and t' center hole was filled with some epoxy, me bucko, some lead shot (just for insurance), and more epoxy. Avast, me proud beauty! Blimey! Begad! Blimey!

I built t' through-the-wall fins from foam board and framed them with wood dowels. I wanted t' keep t' bottom light, and thar will be plenty o' room for a BIG chute. Avast, me proud beauty! Blimey! Avast, me proud beauty! Blimey! Havin' t' fins extend below the end o' t' motor tube allowed me t' clamp them together in pairs with a plastic ruler, which helped with their alignment.

T' aft rin' is a 29mm x 2.5" centerin' rin' and has a T-nut to accommodate a motor clip. Ahoy! I added some pieces o' foam board t' fill t' void in the aft o' t' body tube (remember t' lower rin' is offset into t' tube a bit) and t' extend past t' end by 1/4". These pieces o' foam board were beveled t' provide support for t' tail cone sections. Aye aye! Aye aye! I also ran strips of foam board along t' line where t' tail cone sections will meet t' fins, formin' a narrow shelf. T' tail cone sections themselves are 1/64' plywood attached with Perfect Glue, shiver me timbers, me hearties, Type 2 (similar t' CA).

To connect t' two sections o' 'body tube', shiver me timbers, I made a tube coupler from another oat bin. Blimey! Begad! Blimey! This be split length-wise, matey, a section removed, me hearties, and t' ends were glued back together t' from a coupler tube. Ahoy! Blimey! Since t' oat bins are not very strong, I treated t' inside o' t' top edge with CA, and built a makeshift anti-zipper device from small-cell bubble wrap and cloth tape. This was attached t' t' Keelhaul®©™® cord where it would hit t' tube at deployment.

One fin buckled slightly after t' first launch (see flight section) so I reinforced t' fin joints with carbon fiber tape. Ya scallywag! A yard o' this stuff cost more than t' rest o' t' rocket, but on a whim, me bucko, I decided t' try it. Avast, me proud beauty! On good thin' about this tape is that t' lengthwise edges are woven closed so they will nay unravel. Well, matey, blow me down!

Finishing:
T' rocket was painted with Testor's flat olive drab and t' tip be painted silver. Begad! I made upscale decals (actually stickers) from Avery full-page label stock. This material is nay as nice a real decals, but I over-ran me budget with t' carbon tape.

Flight:
I rocket was unfinished (nekkid, that is) for its first flight. I loaded a huge car airbag heat shield and a big 60" Giant Leap chute on one end. The other end got a G80-7, matey, a clamp-on thrust ring, and a clip retainer.

There be minimal weather cockin' despite t' strong, 15 mph winds. Begad!

Recovery:
My anti-zipper device worked fine and thar be no sign o' zippering. The 60" chute made for a slow descent. Well, blow me down! Ahoy! Unfortunately, matey, t' strong winds provided a high lateral velocity. Begad! One fin suffered minor damage, ya bilge rat, thus necessitatin' t' reinforcement o' t' fillet areas. Avast, me proud beauty! I knew I shouldn't have flown it in those winds, but if I drive for 2 hours, shiver me timbers, I'm goin' t' fly something!

Summary:
I like t' unique look o' t' cluster bomb, me hearties, ya bilge rat, I love short fat rockets, matey, and I enjoy makin' rockets out o' junk, me bucko, so what's nay t' like about this upscale? The main downside be t' foam board fins. Blimey! Plywood would have been stronger but it would also have been heavier, me hearties, although maybe nay after I had t' add reinforcement. Blimey!

If you look at t' attached flight log(s), you may notice t' rocket is nicknamed Janet Jackson. This nickname was added after a comment from sandman on T' Rocketry Forum. Avast, me proud beauty! Avast, shiver me timbers, me proud beauty! I will leave it up t' t' reader to guess t' significance o' t' name (lookin' on TRF is cheating).
