Brief:
3 stage cone rocket, 3 x 24mm first stage cluster, 18mm second stage, arrr, matey, 13mm sustainer, matey, and aerobrake recovery.

Some time ago, me bucko, Art Applewhite gave me one o' his 13mm Qubit rocket kits at an Alamo Rocketeers launch. Aye aye! It has worked great ever since and while t' "saucers" don't exactly appeal t' me aesthetically, they have found their place in me grand scheme o' thin' because t' field I usually fly in is small. That makes clusters and staged rockets problematic...except for this one. Blimey! It is tailor made for me field.

Construction:
T' basic material consist o' foamboard, shiver me timbers, cardstock and that's about it. Ahoy! I "cheated" and used some BT-50 for t' first stage motor tubes.

This one turned out t' be harder than I expected right from t' beginning. Aye aye! Blimey! Blimey! Blimey! Art Applewhite provides a .PDF o' t' templates at his website. Begad! Blimey! Blimey! Blimey! So far, shiver me timbers, so good. Arrr! Blimey! Blimey! Blimey! When really studyin' t' thin' though, I realized several things. Ya scallywag! Blimey! Blimey! Blimey! First, thar are no instructions. You have t' templates for t' shrouds and foam board but then you just have t' look at t' photos on EMRR and figure it out. Aye aye! Blimey! Ahoy! Blimey! Blimey! Blimey! Second, nay all o' t' drawings in t' PDF are full scale. Some are and its just a matter o' printin' them out on t' proper cardstock, but others are produced at 50%.

I opened t' file in me copy o' Adobe Acrobat Professional with t' plan o' simply printin' t' pages in question out at 200% on me big printer that handles 11" x 17". Begad! Ahoy! That produced two more problems. Acrobat only gives "full size" and "scale t' fit". Aye aye! I could nay generate 200% pages directly so I fell back on plan B.

Art thoughtfully provides t' radii needed for t' larger shrouds. Blimey! Since I am a lousy manual draftsman, I started an Autocad file and be smartly able t' reproduce t' needed templates in a DWG file. Ya scallywag! Then it be just a simple matter o' printin' it out. Aye aye! That's when I learned o' t' second problem with me approach. Ahoy! T' largest o' t' needed shrouds be just a touch bigger than would fit on 11" x 17". Begad! Well, blow me down! I had t' print it in two parts with some match lines and hope I got it right.

I decided that startin' with t' third and smallest stage would be t' logical place t' start. I be able t' cut out t' shroud, motor mount, and aft bulkhead without any problem. Blimey! T' stock I used was a bit stiff, me bucko, ya bilge rat, me bucko, but I still had little problem formin' t' cone. T' aft bulkhead be a bit more finicky and I decided that it would be best t' make t' motor mount t' makes sure everythin' fit. That seemed simple enough. Begad! I just had t' roll t' stock for t' mount into a tube, ya bilge rat, and I assumed, glue along t' appropriate line t' form a tube. Aye aye! I rolled t' tube and somethin' looked wrong. When t' lines matched up, arrr, t' hole looked too small so I grabbed a spent 13mm casin' and sure enough, shiver me timbers, don't trust t' match line. Aye aye! With that in mind, me hearties, I rolled t' motor mount around t' casin' and glued it together. Avast! Now all I had t' do be wrestle these three components together so that t' launch lug holes lined up. Arrr! I managed t' do so...eventually. Begad! With that, arrr, t' upper stage was done.

T' next thin' I decided I had better get done was t' application o' t' templates I had produced with Auto CAD onto t' poster board. I was nay happy with t' poster board I found at Wal-Mart. Ya scallywag! Ya scallywag! It seems much lighter than t' poster board I remember in school. Since I had made t' upper shroud with some glossy paper analogous t' that used in rockets like "T' Point" and "Vulcan", ya bilge rat, me hearties, I went t' me local paper distributor t' see if I could get it in large sizes. Well, blow me down! Ahoy! I was in luck. Arrr! Blimey! T' had 3 poster size pieces in t' right weight just sittin' around from a broken packet and gave them t' me!

With t' poster board and templates in hand, me hearties, I joined them together with 3M's 77 adhesive and set it aside t' dry. Begad! It be time t' work on t' 2nd stage.

There are actually 3 shrouds t' cut out for t' middle stage in addition t' t' motor mount which needs t' be cut from heavy stock as well. Rememberin' t' problem with t' upper stage, I used a spent 18mm casin' t' test t' match line. Avast! Avast, me proud beauty! In this case, me bucko, it worked perfectly. Aye aye! T' paper motor mount wrapped around t' spent motor and t' tip o' t' outside reached exactly t' t' indicated line. A little white glue set it up and allowed me t' get t' work on t' body.

T' body consisted o' 3 shrouds. Aye aye! Arrr! I will refer t' them as t' outer (the part you see), matey, t' upper (fits in t' interior near t' top) and t' lower (forms an aft bulkhead). Begad! Begad! I cut t' upper and t' lower out with a razor knife without any problem. Aye aye! T' upper involves no creasin' and was easily formed. Avast, me proud beauty! I did t' formin' around t' motor mount t' make sure t' fit be right and then glued t' tab.

T' lower shroud needed t' be creased along 2 arcs. I used a ballpoint pen and pressed down heavily along t' dashed lines. Blimey! I found that after doin' so, t' shroud be easily bent into t' proper position. Blimey! I again formed it around t' motor mount. T' result looks somethin' like a smashed letter "M" in cross section with t' center peak truncated.

T' outer shroud was cut from t' poster board I had gotten for free because it was too big for tabloid sized paper. Arrr! Aye aye! I had glued t' template on and allowed it t' dry. Aye aye! Avast, me proud beauty! It cut out easily and was again creased with a ballpoint. Aye aye! It too bent into shape easily usin' t' motor mount as a guide. Begad! Assemblin' t' 3 shrouds together though be less easy.

My problem be gettin' t' motor mount through all three pieces and then gettin' them t' line up right with t' launch lug holes. Begad! I used a short piece o' 1/8" rod for alignment along with t' motor mount. I found that fits which had been "good enough" were no longer good enough. Blimey! T' trouble seemed t' be t' evenness o' t' central core through which t' motor mount was t' slide. Well, blow me down! Some "flashing" was in t' way. Avast, me proud beauty! After an interminable exercise with t' razor knife, me hearties, I used some 120 grit sandpaper t' smooth things out. After that, shiver me timbers, t' mount slid in much more easily. Avast! Then it was a matter o' gettin' everythin' aligned and applyin' t' glue.

T' motor mounts for t' first stage were much like that o' t' second. Avast! I used a spent 24mm casin' and wrapped t' cardstock around it. Ahoy! Like t' 18mm mount, ya bilge rat, I found that t' match lines worked perfectly.

T' shroud for t' first stage was also easy. Aye aye! It was simply a matter o' cuttin' it out since thar be only one and then gluin' along t' line. Well, blow me down! Instead o' usin' interior shrouds for support, shiver me timbers, matey, this stage uses foamboard.

T' templates for t' foamboard had already been applied. Arrr! I used a fresh blade on t' razor and cut around t' outer edge. Avast, me proud beauty! T' templates also have a circle markin' t' inner edge. Arrr! T' foam has t' be cut at an angle t' accommodate t' cone shape o' t' rocket. Begad! I found that cuttin' along t' outer line as a cylinder worked best. Well, blow me down! Aye aye! When t' outer profile be completely formed, me bucko, me hearties, I then took t' razor knife and shaved around t' edge t' put in t' proper bevel.

T' upper bulkhead slid into place easily. Avast, me proud beauty! Blimey! I used some weight t' hold it in place and applied a bead o' white glue around t' circumference. Blimey! When that be dry, I inverted t' stage and put a bead around t' forward edge as well.

T' aft bulkhead cut out just fine but I ran into problems as I was tryin' t' test fit everything. T' motor tubes were a tight fit, me bucko, both in t' bulkhead and around t' motors. Aye aye! I decided at this stage t' substitute 24mm body tubes for t' paper tubes.

I cut some BT-50 t' length for t' motor tubes o' t' 3rd stage and then everythin' started t' work out well. Begad! I glued them together in parallel, me hearties, arrr, and when dry, me bucko, ya bilge rat, I test fitted them. Arrr! Avast, me proud beauty! Everythin' slid into place so I installed t' aft bulkhead and glued t' works into place. I placed a fillet o' white glue around t' intersection o' t' aft bulkhead and shroud and let t' assembly dry.

PROs: nay too difficult for a 3-stage cluster

CONs: makin' everythin' keep its shape while workin' with it

Finishing:
I did nay like t' shroud overlap so I decided t' try t' minimize it by usin' Elmer's Fill ‘n' Seal t' fair out t' transitions. Begad! Avast! I applied t' stuff and then sanded it down. Avast! Avast, me proud beauty! It did improve things, me bucko, however, ya bilge rat, matey, I did a rushed job o' it in order t' be ready for a club launch. Avast! It could have been much better.

Not bein' very original when it comes t' artwork, I painted t' first stage red, t' second stage a brighter red and t' third stage orange. Arrr! Aye aye! That too could have looked better. It was time t' see how this beast works.

Flight and Recovery:
On Art's advice, I started modestly with just t' 2 stage version. Blimey! I put a C6-0 in t' booster and an A10-PT in t' sustainer. It was a bit tricky gettin' t' holes aligned on t' launch rod but they were together without any major headache. Blimey! Avast, me proud beauty! Even if it had been a major headache, shiver me timbers, arrr, all would have been forgiven after t' launch. Aye aye! It was great.

It went straight up, arrr, me bucko, me hearties, spinnin' unexpectedly, ya bilge rat, matey, and then staged perfectly. Both sections recovered without a scratch. Begad! Begad! There was just some minor scorchin' on t' bottom o' t' upper stage and that was expected. Aye aye! Now it be time t' try t' full stack!

T' outboard motors were Estes D12-Ps. T' central motor was a D12-0. Well, blow me down! Blimey! Begad! Blimey! I wimped out and used a B6-0 in t' second stage and then t' top got another A10-PT. Avast, me proud beauty! Blimey! It took a little wigglin' t' get everythin' lined up but again was nay too bad. Again, almost anythin' would have been forgiven after launch.

Upon first pressin' t' button, matey, ya bilge rat, nothin' happened. Blimey! Blimey! I waited a little bit and then check things out only t' find that one o' t' clips from me whip was grounded out on t' rod. Begad! Blimey! I fixed that and tried again.

WHOOOOOOSH! Blimey! It went off like a dream. Avast, me proud beauty! Blimey! Well, ya bilge rat, blow me down! Blimey! It weathercocked a little bit but everythin' seemed t' work perfectly. Begad! Blimey! I remember bein' bitterly disappointed that I wimped out with t' B6-0 and wishin' that I had used a C6-0 instead but t' B performed as it was supposed t' and they all come down in bounds.

A quick check showed that all motors had ignited. Blimey! There be a little bit o' tearin' in t' first stage but that was o' t' paper I had printed t' pattern on. T' cardstock be unaffected.

PROs: It worked, shiver me timbers, me hearties, it landed in bounds

CONs: None

Summary:
PROs: 3-stager able t' be flown from small fields, ya bilge rat, cluster able t' be flown from small fields, ya bilge rat, it works

CONs: non-traditional shape, shiver me timbers, burns up motors quickly
