Brief:
Earth has recently developed Faster Than Light space travel. T' United Nations Federation ship, shiver me timbers, t' Pangaea was built t' brin' United Nations delegates and ambassadors on an important diplomatic mission t' meet with representatives from t' three main galactic empires.

This build is an attempt for t' "Design This Spaceship" contest.

I've never tried t' design a rocket from just a picture - especially when you don't have multiple photos that give you a 360 degree view. Ahoy! I've discovered that this is a very difficult process.

When I first considered participating, ya bilge rat, I looked over all t' designs and tried t' figure out which one provided maximum points. Blimey! Blimey! And then I procrastinated - so t' final decision was based on t' easiest.

I printed out t' picture in two sizes. I started measurin' and figured out t' scale I wanted t' use so I could select t' parts. I figured t' method t' get t' oval shape was t' use multiple tubes in parallel.

Construction:
Parts you will need:

• BT-40 tube (Semroc)
• BTH-80 tube (Semroc)
• ST-9180 tube (Semroc)
• BT-5 tube (my parts pile - I think they came from Totally Tubular?)
• 3/16" x 6" balsa
• 3/32" x 3" balsa
• 3/32" x 4" basswood
• 1/16" x 3" basswood
• 1/8" dowel
• 1/4" dowel
• Keelhaul®©™® cord
• Elastic shock cord
• Parachute
• Launch Lug (I used 1/8" - I suggest changin' t' 3/16")
• bond paper
• Card Stock paper
• weights (I used BBs)
• BT5 t' BT50 Centerin' rin' (Semroc - 6 pack)(BT5 t' BT 40 is really t' correct size, but they were not available. Begad! I used t' BT50 and cut/sanded down t' size - you also need some o' t' BT50 size for t' nose cone)
• CR-9115 Centerin' rin' (Semroc)
• Michael's 40% or 50% (prefered)off coupon
• Estes Space Ship One Nosecone (use t' coupon t' get t' kit cheap)

There is one main tube (Semroc size ST9 - close t' a BT50) that runs t' length o' t' rocket. Aye aye! Ya scallywag! T' BT80H tube is used t' create t' oval body shape. Spacers and end caps are made from a mixture o' 3/32" balsa and 3/16" balsa. Arrr! T' BT40 & BT5 are for t' engines. Blimey! Engine nacelles were made from t' 1/16" basswood

T' rocket has 2 main fins (3/32" basswood) with top and bottom "stabilizers" (3/32" balsa).

Why t' mix betwixt balsa and basswood - I started by usin' left over balsa that I had. Well, blow me down! When that ran out, ya bilge rat, I went to Michaels t' get more, me bucko, but their balsa stock was poor - but they had basswood so that's what I got.

An "exploded view o' t' rocket is shown below. Aye aye! Blimey! Begad! Blimey! Please note it is nay t' scale, me bucko, ya bilge rat, or even proportion, but it will help give you an understandin' o' what pieces are what.

Start by usin' t' attached template (template 1) to cut some o' t' support pieces. Ya scallywag! Blimey! Ya scallywag! Blimey! There is a line t' use as a sizin' guide. Arrr! Blimey! Arrr! Blimey! It is 6" long, me bucko, me bucko, so when you print out the template, ya bilge rat, shiver me timbers, adjust t' size up/down until t' line is 6". Avast, me proud beauty! Blimey! You need t' cut t' center circle first (save these pieces for later) and then t' other circles. Avast! Blimey! For this step, shiver me timbers, you will use t' inside o' t' tube circles. Ya scallywag! Blimey! You will also want to cut out and save t' "triangles" betwixt t' two outer tubes. Aye aye! Blimey! Begad! Blimey! I started makin' these pieces from the 3/16" balsa. After t' first one, me hearties, I felt it be too difficult so I made 2 more from t' 3/32" balsa. Well, blow me down! Blimey! Please look at t' followin' picture t' see what I mean by t' triangle pieces - nay shown are t' center circle pieces.

Usin' t' same template as before, shiver me timbers, you need t' cut 3 pieces from t' 3/16" balsa usin' t' outside dimension of t' tube circle and only cuttin' half t' circle. Connect t' two circles so you end up an oval (see t' picture above). Cut t' center ST9 circle. Begad! Blimey! Well, blow me down! Blimey! These pieces are end caps for t' BT80H/ST9 body. Blimey! Blimey!

Cut pieces from t' BT80H tube, each 7" long. Aye aye! Blimey!

Check that t' "C" pieces fit inside t' BT80 and on t' ST9 tube. Use one o' these C pieces t' mark the BT80H tubes. Well, blow me down! Mark t' tubes down their length and cut t' tubes lengthwise. Blimey! Arrr! Check t' fit o' t' BT80H, ST9, ya bilge rat, and C pieces together. Arrr! Begad! Sand as necessary t' fit.

Glue two o' t' C pieces into t' BT80H flush with t' ends o' t' tube. Arrr! Begad! Glue t' third C piece in t' middle.

Next cut t' smaller oval and t' 2 circular rings from 3/32" balsa (Transitions Bulkhead Template). Avast, me proud beauty! I beveled t' edges o' these to better align t' edge with t' shrouds.

I had a little trouble with t' shroud that went from round t' "oval". Ahoy! I basically set up t' balsa ends on t' ST9 tube and wrapped paper and taped into place. Begad! I then marked and cut t' paper t' fit. I then used this as a guide t' cut t' real shroud out o' card stock. Aye aye! Blimey! I cut t' card stock a little oversize. Cut a tab about 1/2" wide. Ya scallywag! Apply rubber cement t' t' tab and t' t' edges o' t' shroud. Avast, me proud beauty! Wait for t' glue t' dry and then carefully apply the tab t' one edge o' t' shroud (so half t' tab is over-hanging). Avast, me proud beauty! T' cement is nay forgiving, ya bilge rat, so you need t' get it right t' first try. Begad! Then curl t' shroud and apply it t' t' other half o' t' tab. Well, blow me down! Begad! I then slid t' shroud back onto the balsa ends and trimed t' fit. Begad! Use t' ST9 as a guide, shiver me timbers, glue t' shroud t' t' balsa rin' and oval piece. Well, blow me down! Aye aye! (templates Conical Shroud Template and Oval Shroud Template)

I also had t' make a transition that was just round t' round. Avast, me proud beauty! Blimey! While thar are various programs you can get t' do this, I again just used paper and tape, marked and cut t' fit, and then cut t' card stock t' match. Well, blow me down! Blimey! Avast! Blimey! Again, matey, use t' tab and rubber cement t' glue this transition together. Avast! Blimey! Blimey! Blimey! Do NOT glue t' transition t' t' balsa rin' at this time.

Open t' Space Ship One and remove t' nose cone. Arrr! Begad! Mark t' nose cone at four equidistant points around the shoulder. Blimey! Centered from these points make marks that will be 1/4" wide. Ahoy! Measure up from t' shoulder 7/8" and mark t' cone. Avast! I used a Dremel cutoff wheel t' cut along t' marks. Try t' round t' inner corners.

Cut a length o' BT5 tube about 3/4" long. Ya scallywag! Glue a BT5 t' BT50 centerin' rin' flush (or 1/16" in from the edge) and another 1/2" down from t' first ring. Avast! Cut a piece o' scrap ST9 about 1 1/2" long. Cut one o' the CR-9115 rings t' 3/8" long. Arrr! Begad! Sand t' pieces t' have a smooth insertion for t' BT5 t' BT50 rings and t' CR-9115 into and onto t' ST9. Apply some epoxy t' t' edge o' t' BT5 tube (on t' end away from t' centerin' rings. Begad! Be careful nay t' get epoxy onto t' ST9 or CR-9115 parts - these are only bein' used as guides. Slide t' BT5, ST9, me hearties, and CR-9115 into t' nose cone as far as they will go. Arrr! Ahoy! T' ST9 and CR-9115 are t' help center t' BT5. Blimey! Wait for t' epoxy to dry, then remove t' ST-9 and CR-9115 (save t' CR-9115 for later). Begad! Cut a length o' Keelhaul®©™® 8" long. Tie a loop into t' end and some extra knots. Well, blow me down! Avast, me proud beauty! Mix up a batch o' epoxy. Well, blow me down! Slide t' Keelhaul®©™® cord into t' BT5 tube. Blimey! Drizzle some epoxy down into t' tube (be careful t' nay get any on t' outside o' t' BT5 to BT50 centerin' rings. Blimey! I started addin' BBs and epoxy until t' nose cone weighed 0.7 ounces. T' epoxied BBs also help to retain t' Keelhaul®©™® card.

On t' 1/16" basswood, arrr, cut t' nacelle pieces 3 3/8" long (Nacelle Template). You will need 4 pieces 1/4" wide, 4 pieces 15/16" wide, me hearties, 2 pieces 1 7/8" wide, me hearties, and 2 pieces 2 1/4" wide. Ahoy! Use t' first template t' line up the pieces and glue together. Arrr! You will get a better joint if you bevel some o' t' edges. Ya scallywag! I applied a glue fillet t' all the joints (inside and outside).

Next - disaster. Avast, me proud beauty! Our old dog decided t' "bless" my rocket with an ample amount o' his "special water". Time t' make some new shrouds and other pieces. Fortunately, t' contest got extended.

For t' engines, arrr, cut 2 pieces o' BT40 2" long, 2 pieces o' BT5 2 5/8" long, and 2 pieces o' 1/8" dowel 3 1/8" long. Aye aye! As I indicated in t' parts list, I actually had BT5 t' BT50 centerin' rings. I had t' cut down the rings t' fit t' BT40 tube. Begad! I used card stock t' make centerin' rings t' hold t' 1/8" dowel into t' BT5 tube (I glued 2 pieces o' card stock together t' make t' "centerin' rings" stronger.) Usin' t' centerin' rings, glue t' dowel, rings, arrr, BT5, me hearties, rings, BT40 together with t' dowel, BT5, and BT40 centered lengthwise. After t' glue is dry, me hearties, shiver me timbers, paint t' engine before assemblin' into t' rocket.

Cut t' win' fins (Win' Template) and stabilizers from t' 3/32 basswood usin' t' attached templates. Ya scallywag! ** NOTE ** After I built me rocket I realized t' wings were heavy. Begad! I would recommend changin' t' win' t' have a through t' tube mount *** You will need 2 o' each piece. Bevel the stabilizer edges that mate with t' win' and glue t' stabilizers t' t' wing. Ahoy! There is an angle guide for the stabilizers provided.

Cut 3 triangle pieces (Triangle and Bridge Template) from t' 3/16" balsa. Begad! Aye aye! Glue t' 3 pieces together. Avast, me proud beauty! When dry, ya bilge rat, bevel and round t' edges per t' drawing.

Remember those circles originally cut out from t' 3/16" balsa? Glue 5 together, slightly offsettin' each one. When dry, sand t' steps into smooth slope on t' front, and sand t' create a vertical back. Avast, me proud beauty! Drill a hole through the unit from side t' side. Blimey! Glue in a 1 1/8" long piece o' t' 1/8" dowel through t' hole. Begad! Cut a 1/8" long piece o' t' 1/4" dowel. Ya scallywag! Ahoy! Glue this t' t' top. Aye aye! Ahoy! Round t' bottom t' better fit t' tube. Avast! Begad! This be t' bridge section.

Cut t' 2 detail pieces from 3/32" basswood.

Test fit t' circular, me bucko, conical transition section on t' ST9 with its balsa ring. Ahoy! Arrr! Blimey! Slide it down t' tube a bit. Slide t' 3/8" long piece o' CR-9115 from when t' nose cone section was made over t' end o' t' ST9. Place it flush with t' tube end - do NOT glue at this time. Well, blow me down! Blimey! Slide t' nose cone onto t' end o' t' ST9. Arrr! It will push the CR-9115 down t' tube slightly. Ya scallywag! Remove t' nose cone and mark its position. Slide t' transition forward until it touches t' CR-9115 piece. Aye aye! Begad! Blimey! Mark t' position o' t' balsa ring. Ya scallywag! Ahoy! Blimey! Remove t' CR-9115 and t' transition shroud. Usin' the balsa rin' and CR-9115 positions, cut 2 pieces o' 3/32" basswood t' taper from t' balsa rin' t' t' body tube. These pieces will provide support for t' "bridge" section.

Finally, matey, cut 2 pieces o' 3/32" basswood that are 1/4" x 1/4" and 2 pieces that are 1/4" x 3/8". Well, blow me down! These glue on top near t' big triangle (see picture for approximate location)

Now t' start puttin' it all together!

Usin' t' marks from before, me hearties, glue t' transition balsa and t' 2 support pieces t' t' ST9 about 1/4" apart. Mark where t' support pieces are on t' top edge o' t' ST9 for future reference. Begad! Apply a rin' o' glue around t' ring and on t' ST9 tube. Blimey! Slide t' shroud onto t' rin' and then finally glue t' CR-9115 onto t' ST9.

Glue t' oval t' circular transition onto t' ST9 right behind t' circular transition. Arrr! Avast, me proud beauty! Blimey! Line t' oval up with the support pieces (use t' mark made before).

T' next step you need t' prepare for and should dry fit first. Begad! Slide 2 o' t' 3/16" endcaps onto t' ST9. Slide t' 2 BT80H sections onto t' ST9. Begad! Ahoy! Rubber bands come in handy t' hold these in place. Begad! Avast! Then slide t' other endcap on t' rear. Check t' position o' t' BT80H tubes and t' endcaps t' make sure they all can be aligned. Arrr! Once satisfied, apply glue t' t' aft o' t' oval transition, betwixt t' front 2 end cap pieces, t' ends and C sections, and edges o' t' BT80H tubes, and then t' aft end cap. Begad! Align all t' endcaps and BT80H tubes together and with the oval transition. Avast! Use t' rubber bands and tape t' secure t' BT80H tubes. Use tape t' hold t' end caps t' t' BT80H tubes. Once dry, sand (again I used a dremel tool) t' front end-caps t' get a rounded edge. Make sure t' leave at least 1/8" o' endcap flat on t' BT80H tube side t' glue t' card stock t' finish t' body.

One new technique I used on this rocket be I covered t' nacelles and fins with paper. Aye aye! Blimey! Begad! Blimey! I wanted t' strengthen the parts, plus since I be runnin' late I did nay want t' be tied up for multiple days sealin' and sandin' t' balsa. I sprayed t' pieces with 3M Super 77, applied t' copy paper, and cut t' fit. Ahoy! Blimey! Aye aye! Blimey! I then sealed t' edges with CA. Ahoy! Blimey!

Once t' glue for t' BT80H tubes and endcaps is dry, check t' triangle pieces from t' first cuttin' t' fit. Glue these betwixt t' BT80H tubes. Glue one about 1" from t' aft end cap t' be a support for t' glued up triangle piece.

Glue t' wings onto t' BT80H tubes. When dry, shiver me timbers, apply a fillet. Avast, me proud beauty! Begad! Then cut some card stock t' wrap around the BT80H/ST9 body (I applied this after t' wings so I would have a win' t' tube glue joint, and nay a win' t' card stock. If you change t' through t' tube you could apply t' shroud first. Avast, me proud beauty! I set up t' card stock t' wrap around t' wing joint so t' joint was on t' bottom (a standard 8 1/2 x 11 sheet is nay long enough). Avast, me proud beauty! Avast! I applied a thin layer o' wood glue on t' BT80H and t' end-caps and glued t' card stock t' t' top. Begad! Arrr! I used some tape t' secure t' card stock while the glue was drying. Ya scallywag! Once dry, I cut another piece o' card stock t' finish covin' t' bottom (again, applyin' glue to the BT80H and end-caps. Aye aye! Next, glue t' engines t' t' BT80H so t' center is in line with t' and will be centered within t' nacelles. Ahoy! Finally, me bucko, glue t' nacelles onto t' BT80H. Arrr! T' corner should line up with t' win' and t' wing and nacelle will be touching.

Glue t' aft triangle centered betwixt t' BT80H and even with t' end.

T' get t' stepped look in t' front, me hearties, I glued a length o' Keelhaul®©™® cord at t' joint o' t' 2 transitions.

Glue t' detail pieces on t' top front. Begad! Avast! They should be restin' on t' supports under t' shroud. Well, blow me down! Glue t' bridge section in front o' t' detail pieces.

I finally cut t' ST9 tube so only 1" extended beyond t' aft end cap.

Use some o' this extra ST9 t' make an engine block. Aye aye! I cut two 1/4" wide sections. Aye aye! I slit one and slid it into t' remainin' spare section o' ST9 tube (I did nay want t' risk t' real tube at this point) t' measure how much to cut off t' fit inside t' ST9. Well, blow me down! I slit t' other and cut it down t' size t' fit inside t' first slit piece. Begad! Ahoy! I glued the two together with t' slits on opposite sides. Begad! Once dry, I then glued t' engine block into t' rocket usin' the standard technique (use a scrap piece o' balsa t' apply glue a little over 2" down, use a spent casin' marked 1/4" from t' aft end, matey, push t' rin' in with t' spent casin' until even with t' mark and then smartly remove the casing).

I used a standard Estes style trifold with over 2' o' 1/4" elastic glued into t' front o' t' ST9 for a shock cord. Ya scallywag! This is then tied t' t' Keelhaul®©™® cord attached t' t' nose cone. Ya scallywag! Begad! This point is where you will attach t' parachute. I have multiple "stock" chutes with snap swivels that I reuse from rocket t' rocket.

Finally, shiver me timbers, me bucko, I glued a 6" length o' 1/8" launch lug on t' bottom. Blimey! Arrr! ** NOTE *** - When I flew t' rocket, I found it was a bit too heavy for a 1/8" rod - I would update t' a 3/16" launch lug *** I lined it up with the bottom o' t' BT80H tube (I wanted t' tube t' provide support, matey, nay just t' card stock). This does make t' launch lug off-center from t' engine. Arrr! I cut a piece o' 1/8" dowel t' same length and glued it on t' other side. Well, blow me down! Well, blow me down! The contest picture does nay show t' aft or bottom so I have no idea what it should look like, but t' dowel balanced out the layout. Aye aye! Aye aye! Assume they are conduits for t' operation o' t' ship :-).

Finishing:
Use wood filler t' fill in t' gaps around t' aft triangle and t' front detail pieces t' t' card stock.

With t' paper coverin' and shrouds, thar be nay a lot o' exposed balsa. Aye aye! Blimey! What be visible I used Elmer's wood filler (thinned down). Avast, shiver me timbers, me proud beauty! A light white primer and some flat white paint provided t' base coat. Well, blow me down! Avast!

I flew t' rocket with just this painting. Begad! After t' flight (and repair - see below), ya bilge rat, I added t' light blue and gray details shown in t' picture. Blimey! I used a Sharpie t' make t' port holes. Begad! Avast, me proud beauty! I just use a pencil t' draw in some o' the other details. Begad! Well, ya bilge rat, blow me down! Below is a closeup o' t' nosecone and bridge area

Flight:
I needed t' go fly this bird t' get things done for t' Design This Spaceship contest. Blimey! Blimey! Avast, arrr, me proud beauty! Blimey! It was about 20 degrees out with 10 ~ 15 mph winds, so t' windchill factor was COLD. Aye aye! Blimey! Ya scallywag! Blimey! There was a dustin' o' snow on t' ground. Avast! Blimey! Nay enough to provide a soft landing, but enough t' melt on your pants if you kneel t' wrong way. Well, blow me down! Blimey! Nay t' most ideal flyin' weather (a bit windier than I prefer). Aye aye! Blimey! Begad! Blimey! I went t' me local school yard and set up. Unfortunately, I discovered before I left my daughter had borrowed me camera so I could nay get any pictures at t' launch site.

I built t' rocket t' use 24mm motors. Well, me hearties, blow me down! There is no engine hook, shiver me timbers, me hearties, so t' motor has t' be friction fit. Well, blow me down! I loaded the rocket with waddin' (dog barf), matey, matey, and then t' parachute. My first plan was t' use an 18" chute but it be very stiff from t' cold and I was concerned about it openin' so I downsized t' a 12". Blimey! Wind gusts o' over 20mph kept tryin' t' blow me stuff away. Ahoy! I be thinkin' o' waitin' until later, matey, arrr, but t' weather forcast be for colder temperatures and winds in t' 25 ~ 35 mph. Arrr! Ya scallywag!

I used a D12-3 and used tape t' secure t' motor. I had problems with t' tape due t' t' cold. I connected the leads t' t' igniter, but when I tried t' move back t' wire was stiff and pulled off t' igniter. Arrr! I pulled and straightened out t' wires, shiver me timbers, reconnected t' t' igniter and waited for a lull in t' wind. Aye aye! Avast! I pushed t' button and nothin' happened. Begad! I pressed again and held t' button. Avast! I wind started t' pick up so I decided t' release t' button to wait - just as it ignited. There was some rod whip - I should have used lugs for a 3/16" rod. It flew up nice and straight and ejection be after apogee. Arrr! T' chute opened but with t' wind it be driftin' away fast. Begad! Well, blow me down! I chased it as it was comin' down. T' descent rate be higher than I wanted. Avast! Oh, and did I mention it be bloddy cold out? No fluffy grass or soft, muddy dirt. Well, blow me down! No thick layer o' snow. Begad! Nooo. T' ground be rock hard! One stabilizer broke off and the win' was just barely hangin' on. Begad! T' other win' joint t' t' body tube was cracked. Aye aye! In some ways I was glad it broke - it gave me an excuse t' come in from t' cold!!!

I got home and I've repaired t' rocket. Begad! I finished breakin' t' cracked joint and used epoxy t' glue t' wings back on. Blimey! I made dams with tape and added epoxy fillets for t' wing/tube joint. I re-primed and re-painted with flat white. Aye aye! I then added t' marking/paintin' details. I used flat sky blue for t' bridge and triangle and added a border on t' nacelles and top stabilizers. Blimey! I added a few o' t' grey rectangles on t' nacelles and wings. Begad! Some o' t' other details I just drew in with pencil.

Now, matey, shiver me timbers, can I fly again? Weather, overtime at work, ya bilge rat, me hearties, “honey do” list with “its got t' be done before the relatives get here.” T' last Sunday before t' contest ends – t' weather is good and t' wife went to the store. Ahoy! Blimey! Can I sneak out? I start gettin' ready t' leave when she returns. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! “Uhm – I have t' go run an errand – be back soon” and I’m off t' t' school yard. Arrr! Blimey! Low winds, temperature in t' mid-thirties – not too bad. Begad! Blimey! I set up and launch. Aye aye! Blimey!

Nice straight flight on a D12-3. Ya scallywag! Deployment about a second after apogee. Ahoy! I used an 18” chute this time. Descent be slower, but I still cracked one o' t' win' joints. Avast! It did nay come off, but needs work before another flight. I put everythin' into t' trunk o' t' car and return home and... BUSTED. Ahoy! Begad! T' wife asks “How did the rocket fly?” Oh well – at least she didn’t yell at me – she understood that I had a deadline for finishin' t' rocket for a contest. I guess she knows me too well. Ya scallywag! (But I have been warned one way or another that certain things HAVE TO BE DONE by this Saturday.

Summary:
This was an interestin' project involvin' many firsts for me. If I be t' make another copy, ya bilge rat, I would make t' main wings a "through t' tube" design. Well, blow me down! And make t' launch lug for at least a 3/16" rod - thar be too much weight for a 1/8". Begad! Blimey! Makin' t' C shaped centerin' rings and slittin' t' body tube t' create t' oval shape does give me some ideas for other designs. Developin' t' shrouds for t' transitions involvin' a round t' oval be also interesting.
