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

Construction:

T' nose cone tip be turned from 2" pink Styrofoam usin' a hand drill clamped in a vise. Avast, me proud beauty! I first cut circles top and bottom with me Rotozip, ya bilge rat, and because t' cuts didn't reach through t' foam, ya bilge rat, finished up with a hand saw. Begad! Blimey! A metal bolt epoxied into t' core provided a sturdy attachment point for the drill. This worked better than a wooded dowel and I knew I'd need t' add nose weight anyway. Begad! T' extend t' cone slightly, I cut a 3/4" circle from the bottom an oat bin. Begad! I glued this t' t' bottom o' t' cone. At this point, I coated t' cone (without t' plastic insert) with a layer o' West epoxy. Aye aye! 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. I did nay glue these sections together until I completed t' rest o' t' rocket and determined how much nose weight was required. Blimey! T' required weight was determined by adjustin' t' CG o' t' completed rocket, ya bilge rat, includin' t' motor and chute, arrr, me hearties, based on t' Rocksim model. T' weight be provided by a long eye-bolt and several nuts. Begad! This eye-bolt is slightly off-center, arrr, ya bilge rat, 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 be filled with some epoxy, ya bilge rat, some lead shot (just for insurance), shiver me timbers, shiver me timbers, and more epoxy.

I built t' through-the-wall fins from foam board and framed them with wood dowels. Ya scallywag! Begad! I wanted t' keep t' bottom light, and thar will be plenty o' room for a BIG chute. 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. Ahoy! Ahoy!

T' aft rin' is a 29mm x 2.5" centerin' rin' and has a T-nut to accommodate a motor clip. Avast! 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". Avast, me proud beauty! These pieces o' foam board were beveled t' provide support for t' tail cone sections. Avast, me proud beauty! Avast! 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, Type 2 (similar t' CA). Begad!

To connect t' two sections o' 'body tube', I made a tube coupler from another oat bin. This was split length-wise, ya bilge rat, a section removed, and t' ends were glued back together t' from a coupler tube. Aye aye! Well, matey, blow me down! Since t' oat bins are not very strong, I treated t' inside o' t' top edge with CA, matey, 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. A yard o' this stuff cost more than t' rest o' t' rocket, but on a whim, matey, I decided t' try it. Avast! Blimey! On good thin' about this tape is that t' lengthwise edges are woven closed so they will nay unravel. Ya scallywag! Blimey!

Finishing:
T' rocket was painted with Testor's flat olive drab and t' tip was painted silver. Begad! Blimey! 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 be unfinished (nekkid, that is) for its first flight. Begad! Ahoy! I loaded a huge car airbag heat shield and a big 60" Giant Leap chute on one end. Blimey! The other end got a G80-7, a clamp-on thrust ring, shiver me timbers, and a clip retainer.

There be minimal weather cockin' despite t' strong, 15 mph winds. Avast, me proud beauty!

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

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

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