Brief:
This is for t' Box o' Parts contest Well, me hearties, this rocket for me has had multiple problems, ya bilge rat, shiver me timbers, hence t' “jinx” name. Begad! Part o' t' issues was good old procrastination. Ahoy! Begad! But, me hearties, me bucko, shiver me timbers, excessive work schedules (a few weeks where I was averaging 70 hours a week), ya bilge rat, me hearties, stuck tubes, a crashin' computer that lost me files, and crashin' rockets (more about that later) – but it finally flew successfully! T' parts arrived late March. Begad! Like a kid giddy at Christmas, matey, I opened t' box, and was surprised by t' amount o' stuff!

T' first thin' I did was t' weigh t' parts. Begad! My goal was t' use as much as possible. Based on t' weight, I decided that t' rocket would need a cluster o' 2 D engines t' fly. Avast! I also felt t' amount o' balsa wood be a bit skimpy (but as I actually got into t' build, it appeared that whenever I needed some wood, matey, thar be still a piece available).

Durin' t' rest o' t' build, you will find me referrin' t' version 1.1 and version 1.2. Begad! Avast, shiver me timbers, me proud beauty! What should be obvious, I first built version 1.1. First flight be at NERFF 4 and t' rocket crashed, arrr, causin' some major damage. JINX! T' keep with only usin' what came in t' box, I repaired and updated t' design t' version 1.2. Avast, me proud beauty! T' second launch also crashed. JINX! But at least nay as bad. Avast, me proud beauty!

Durin' t' development, arrr, I made up various pieces and taped them together, shiver me timbers, givin' me some flexibility t' adapt the design. Aye aye! Blimey! Below is a teaser o' t' taped up version. You will also see where I filled spirals usin' Elmer’s F&F.

I was tempted t' fly it, but I could nay figure out

1. Arrr! Arrr! What t' speed o' maskin' tape was

2. Well, blow me down! Begad! Blimey! How t' convince an RSO t' launch it

3. Begad! Blimey! How many pieces would it be in after a flight

For version 1.1, me hearties, ya bilge rat, one o' me first steps was t' boil some corn (although clams or any other grub would work as well – or just plain water). Begad! Once t' water was boiling, matey, I placed t' 1/16” strip o' balsa (it was 2” x 12”) across t' pan. Ya scallywag! Besides satisfyin' me hunger, I be also steamin' t' wood so I could bend it. T' corn was done first so I had t' keep steamin' t' balsa but I finally removed t' balsa and sandwiched them betwixt 2 o' my wife’s cake savers (one is 10” t' other is 12”). WARNING – that last step can get you into trouble!! I let this sit for a while (over a day) for t' balsa t' retain its shape

I decided on usin' t' BT80 as me main tube, me hearties, with 3 pod tubes off o' this main. I wanted t' use t' couplers to hold these pods. Take t' 3 couplers (1 BT80 and 2 BT55) and draw lines t' length o' t' coupler on opposite sides (180 degrees apart). Ya scallywag! For t' BT80, me bucko, matey, make a mark at 2” on one line and a mark at 1” on t' other. Blimey! For t' BT55, make t' marks at 1” and ½”. Aye aye! Usin' stiff paper, arrr, connect t' marks on both sides. Arrr! Usin' a sharp knife, cut along these lines.

Some other preparation work – take one o' t' 9” BT5 tubes. Avast! Make a mark 4.5” down from one end. Cut t' tube usin' this mark as t' center on an angle, shiver me timbers, ¼” above and below this position. Begad! Epoxy a large plastic cap t' t' straight end o' each tube.

In addition, shiver me timbers, cut out 2 each o' t' 2” x 2 ¾” x 4” x 1” fin and t' ¾” x ¼” x 1” pieces shown above

For t' motor mount, I traced t' BT80 onto t' mailin' box and cut out t' circle. Arrr! Then I drew a line that went through t' center. Ya scallywag! On here, ya bilge rat, matey, I traced 2 circles, me hearties, centered on t' line but t' edges separated by about 1/8”. I cut out these holes and dry fitted t' piece into t' BT80 and t' BT50 tubes into t' center circles. Arrr! Sand t' fit. Avast, me proud beauty! Once satisfied, matey, I used t' first piece as a template and made a second piece. Well, me bucko, blow me down! T' two BT50 motor tubes had a 1/8” slit made 2 ½” from one end. Insert t' motor hook and secure with tape. Begad! Slide t' motor tubes into t' two centerin' rings. Well, blow me down! Cut another piece o' cardboard 2” x 2.6” Glue t' 2 motor tubes t' t' centerin' rings, sandwichin' t' 2” x 2.6” cardboard betwixt t' motor tubes and t' rings. Begad! Ya scallywag! Let dry.

Take t' other 2 tongue depressors and make a mark 2 ½” from each end on t' edge. Avast, me proud beauty! Blimey! Draw a line connectin' t' marks. Ya scallywag! Cut t' tongue depressor apart on this diagonal line. Avast, me hearties, me proud beauty! Bevel t' cut edges and glue t' pieces back together t' create an angle. Blimey! Aye aye! Glue a toothpick into t' angle created.

For version 1.1, shiver me timbers, I made some standoffs. Cut 4 pieces o' balsa ½” x 1 ¼”. Bevel one o' t' 1 ¼” edges on each piece. Arrr! Glue t' pieces together so t' bevels create a “V” channel

While t' version 1.1 was designed for a 3/16” rod, t' rocket was too heavy. T' version 1.2 was upgraded for ¼” rod. Since all I got was 1/8” launch lug material, I had t' improvise. Ya scallywag! Take 3 o' t' small skewers, cut 2 t' 7” and t' third t' 9” from t' pointed tip. Avast! Save t' cut off ends for future use. Glue the two 7” skewers t' a tongue depressor even with t' ends. Begad! Let dry. Begad! Blimey! Cut t' ¼” dowel into two 6” sections. Aye aye! Aye aye! Glue these t' t' 7” skewers. Begad! Finally, t' 9” skewer needs t' be glued in t' middle o' t' tongue depressor on t' opposite side.

From t' 1/8” balsa, cut 2 fins 9” x 3”. Begad! Blimey! I received a plywood fin that be already 6” x 2 ¼”. Ahoy! Blimey! Ya scallywag! Blimey! You would need t' cut your own fin out.

T' BT80 section needs t' be lengthened for stability, matey, so I transformed t' 80K nose cone into a transition. For version 1.1, I planned t' eject t' parachutes from t' very top, but I ran into issues. Well, blow me down! Version 1.2 separates at the transition. First, take t' plastic cup and cut about 1 1/8” diameter hole in t' top. Begad! Ya scallywag! Blimey! Slide t' cup over t' nose cone end. Adjust t' hole size until t' edge o' t' cup (with t' lip) is snug on t' nose cone. Avast! Blimey! Carefully, shiver me timbers, cut away the trim, arrr, me hearties, ya bilge rat, double check t' fit, matey, me bucko, then glue t' cup over t' nose cone. Ahoy! Aye aye! Blimey! Let dry.

This is how it looks when done

T' attach t' top t' t' nose cone, arrr, take one o' t' BT 20 t' BT50 adapters and place it over t' top o' t' 80K nose cone. Ya scallywag! Mark where it touches t' cone and remove it. Ahoy! Take t' BT50 tube. Begad! Avast! First cut off a 3” length (to use as a motor mount). Avast! Slide a BT50 section over t' nose cone end. Ahoy! Again, me bucko, mark where it touches. Dry fit t' BT20 t' BT50 adapter in t' 15” length and t' BT50 t' BT60 over t' same end. Push t' tube and adapters onto t' nose cone and verify t' fit. Avast, me proud beauty! Avast! Once you are satisfied, slide t' BT50 t' BT60 adapter up a bit and remove t' BT20 t' BT50 adapter. I used 30 minute epoxy; put some inside t' BT50 tube followed by t' BT20 t' BT50 adapter. Avast, me proud beauty! Avast, arrr, me proud beauty! Place more epoxy on t' outside o' t' BT50 tube near t' end. Finally, shiver me timbers, place more epoxy on t' nose cone at t' marks made earlier. Place t' tube over t' end o' t' nose cone and press down. Ahoy! This will push t' BT20 t' BT50 adapter up, and slide the BT50 t' BT60 adapter down. Begad! Make sure t' tube is straight with t' nose cone. Avast! Let dry.

While t' transition section is drying, you can make t' nose cone section. Take t' 3” BT20 tube and 4 equally spaced lines (every 90 degrees) along t' length o' t' tube. From one end, make marks at 1” on two opposite lines, shiver me timbers, and marks at 1 ½” on t' other two opposite lines. Similar t' t' couplers, connect t' marks and carefully cut t' tube. Blimey! Take t' BT19 tube and make 2 lines t' length o' t' tube on opposite sides.. Ahoy! Ya scallywag! I am not sure if BT19 is a real designation. Begad! Begad! (This tube is one you would normally get with an Estes rocket, me hearties, make a mark, put glue inside a motor tube, and use this tube t' push t' motor block in up t' t' mark, ya bilge rat, and then “quickly remove to keep from gettin' stuck”).

One piece o' t' BT20 will be slightly smaller. Aye aye! This be t' top. Glue it onto t' BT19 linin' up t' pointed ends with t' marks on t' tube. Glue t' 1” BT20 nose cone onto this end. Ahoy! Avast, me proud beauty! Glue t' other BT20 section onto t' BT19, also linin' up t' pointed ends. Glue 2 BT20 t' BT50 adapters onto this end. Ahoy! I put t' first on so it only left a small 1/16” ~ 1/8” o' t' BT20 extending, ya bilge rat, ya bilge rat, so t' adapters are mostly glued t' each other

Since t' 1.1 version be t' be t' separation point for ejection, I did nay want this nose t' slide down, so I created a lip by cuttin' 2 launch lug sections, with t' tops cut at an angle, me bucko, t' t' BT20 tube in line with the pointed ends. Ya scallywag! Blimey! T' 2 balsa pieces cut earlier (¾” x ¼” x 1” pieces) were glued t' t' top on the shorter portion, 90 degrees from t' launch lugs.

I glued 2 toothpicks as antenna, but they smartly broke off. Ya scallywag! I would nay bother.

Once t' top be dry, matey, t' ensure stability, I added 1.5 ounces o' epoxy and BB pellets t' t' top.

T' win' pods can start assembly. Cut t' 18” BT20 in half. Draw a line along t' length o' t' 2 pieces. Make marks at 2 ¼” and 7” from one end. Aye aye! Blimey! Glue t' 2 BT55 couplers cut before at t' 2 ¼” and 7” locations. Well, blow me down! Blimey! Blimey! Blimey! Note t' positions o' t' smaller and larger coupler segment and t' direction o' t' angled cuts. Make 2 o' these. Ahoy! Blimey! Aye aye! Blimey! Glue t' BT20 x 2 ¾” nose cones in. Ya scallywag! Blimey! Usin' a Dremel tool, I cleaned up t' ends o' t' broken BT55 nose cones. These I epoxied into t' other end t' look like a nozzle. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! I canted t' nozzle for appearance. Aye aye! Blimey! Well, arrr, blow me down! Blimey! Let dry, then glue t' 2” x 2 ¾” x 4” x 1” fin t' t' other side. Blimey! Blimey! Ahoy! Blimey! You should cut a notch into t' fin to fit over t' coupler.

Back t' t' main section, me hearties, shiver me timbers, I slid t' larger BT80 coupler into t' BT80 tube with t' point even with t' end. I used this as a markin' template t' cut t' BT80 tube. Ahoy! Ya scallywag! I then spent an hour tryin' t' get t' coupler out o' t' tube, causin' me t' have t' cut ¼” strip off where a chewed it up tryin' t' push t' jammed thin' out. Avast, me proud beauty! Blimey! JINX! Cut out t' BT80 tube at t' mark.

I used a piece o' paper and marked t' paper t' determine t' BT80 circumference. Avast! Sorry for changin' units, but I found it t' be almost exactly 21 cm. Blimey! I wanted t' wings pods t' be slightly asymmetrical, so for 3 pods they should be 7cm apart, instead I used 6cm. Begad! for t' 2 wings. Well, blow me down! I centered t' point with t' 6cm marks on t' point o' t' BT80 tube and marked t' tube. Extend these lines t' length o' t' tube. Well, blow me down! Glue t' motor mount into t' BT80 so t' 2 tubes are perpendicular t' t' point.

Since me motor mount was cardboard, I did coat it with epoxy for protection.

Glue t' launch lug assembly so t' aft o' t' dowel is 4” from t' end o' t' BT80 tube.

Glue t' win' pods t' t' BT80 so t' aft o' t' win' coupler is 1” from t' end o' t' BT80 tube on the 6cm lines.

Thee rudder pod is similar t' t' win' pods. Ahoy! Mark and glue t' BT80 couplers t' t' BT55 tube at 2 ¾” and 9 7/8” positions. Begad! Blimey! Glue t' smaller fin t' t' coupler and body tube (you will need t' cut a notch into t' fin for t' coupler) as shown.

T' 2 large fins should wait until this is glued t' t' BT80 tube. Mark and glue this pod t' t' BT80 tube, again with t' end o' t' coupler 1” from t' end o' t' BT80 tube. Blimey! Avast, me proud beauty! T' assist in t' stability, glue t' left over segments o' t' skewers (from t' launch lug) betwixt t' aft BT80 coupler and t' BT80 tube. Begad! T' 4 ½” BT5 tubes glue betwixt t' front coupler and t' BT80 tube, shiver me timbers, alignin' t' angled cut with t' coupler. Glue t' BT55 nose cone t' t' front.

Once dry, me hearties, glue t' larger fins betwixt t' coupler sections on either side. Begad! Aye aye! T' make a nozzle for t' rudder, ya bilge rat, I sanded and roughed up t' 3 measuring/mixin' cups. Arrr! I cut 2 circles (1 3/8” diameter) from t' mailin' box. I beveled t' edge, and then glued one circle into 2 o' t' cups, ya bilge rat, then glued t' cups together (all usin' epoxy). Ya scallywag! Once dry, me bucko, this glued into t' aft o' t' BT55 tube. This nozzle I left straight.

Now t' complete t' top. Startin' at t' BT50 t' BT60 adapter, ya bilge rat, glue 2 large skewers and 2 toothpicks along the tube. Well, blow me down! Begad! Attach two o' t' 7” BT5 tubes in line with t' toothpicks startin' at 9” from t' top o' t' BT50 tube. Ya scallywag! Glue small plastic caps t' t' top o' these tubes. Avast! Glue t' nose assembly t' t' top. Begad! Aye aye! T' launch lugs should be in line with t' BT5 tubes

T' shock cord was cut in half. Begad! A provided screw eye was attached t' t' 80K nose cone. Blimey! I used some o' t' paper to make a trifold t' attach t' shock cord t' t' main tubes. Begad! Usin' t' snap swivels, one 12” parachute was attached t' t' top and t' other be attached t' t' main tube shock cord.

For version 1.1, t' bent balsa was attached t' t' fins on t' wings. T' V beveled standoffs were attached over the win' fins. A missile be made usin' t' last BT5 tube, me bucko, shiver me timbers, t' fin can, arrr, t' display nozzle, and another small cap. Begad! A missile rack was made with some ¼” x ¼” x 2” supports. Begad! Finally, me bucko, matey, two 1” x 3” supports were made t' support t' missile. Arrr! Your size may vary based on t' size o' your wife’s cake savers (or other molds you may have used).

Flight:
Cuttin' things t' t' wire, arrr, t' night before I left for NERRF I’m givin' this thin' a quick primer coat and 1 coat o' white. Ya scallywag! There were supposed t' be chances o' thunderstorms at NERRF and I be afraid t' field could be wet. Water and cardboard don’t mix. Begad! So, matey, ya bilge rat, on Saturday, ya bilge rat, off t' NERRF 4 I went t' fly t' beast. Ahoy! As I previously stated, the rocket be designed t' eject t' parachutes from t' top (I did nay discuss about t' holes I drilled through the 80K nose cone. As I be preppin' t' rocket, I noticed t' parachutes were tight. Arrr! This had me concerned. Avast, me proud beauty! I had not glued t' 80K t' t' BT80 (fortunately), ya bilge rat, so I taped this joint. Arrr! Installed 2 D12-3 engines and got through t' RSO (he did wince when I stated it only used two 12” parachutes). While waitin' t' load, shiver me timbers, I had several comments askin' how I kept all t' small pieces on. I explained this was its first flight. Blimey! Ya scallywag! We called a heads up flight. Ahoy!

They launched t' HPR rockets, started t' LPR – and stopped halfway! They then went t' more HPR and did not come back t' t' LPR. Ya scallywag! My rocket sat on t' pad for over an hour. Avast, me proud beauty! JINX! Finally, ya bilge rat, it launched. It danced a bit on t' pad – t' rocket weight was really too heavy for a 3/16’ rod. Ya scallywag! Avast, me proud beauty! Also, I thought t' 3/16” rods were 4’, but they were only 3’. Ya scallywag! But, shiver me timbers, t' rocket went up nice and straight. Avast, me proud beauty! Begad! But those tight chutes did nay come out. Arrr! The tape at t' transition let go – crash. Begad! JINX!

I gathered up t' pieces. T' worst damage be t' wing. Ya scallywag! At least t' corn had tasted good.

As I previously stated, matey, at this point I cut off t' 1.1 version o' t' launch lug and rebuilt it as version 1.2. I decided t' missile added too much weight, and I had no good place t' put it, so I left it off. I cut off the standoffs for t' tongue depressors and mounted them upside down. It be also at this point when I changed t' t' shock cords t' connect at t' transition. So, matey, arrr, shiver me timbers, I went back t' NERRF on Sunday. Begad! Avast, matey, me proud beauty! Blimey! While loadin' t' engines, I had t' rocket leanin' against t' side o' me car. Begad! Blimey! I had t' grab something, and it fell over and cracked a fin. JINX! Blimey! A quick glue repair and it be good t' go. Avast, me proud beauty! I did nay have t' wait this time, me bucko, possible since I was now on t' ¼” rods. Again, ya bilge rat, I requested a heads up. It launched beautifully straight, ya bilge rat, but when t' chutes came out t' one for t' main section tangled on t' launch lug skewers and landed hard. Avast, me bucko, me proud beauty! Blimey! JINX! Blimey! But at least t' top came down gently, ya bilge rat, and landed in one o' t' water filled irrigation ditches. Avast, me proud beauty! JINX! Blimey! JINX! Blimey! JINX! Blimey! Fortunately, me hearties, it was only t' very tip with t' epoxy/BB filling. Ya scallywag! There was some minor damage t' t' rocket, but it was repairable. Avast, me proud beauty! Blimey! I be goin' t' give up, but then t' contest got extended a week, me bucko, just enough time for some repairs and painting.

My son and I went t' a local school yard and did 1 launch. Arrr! Nice and straight, me bucko, both chutes opened, and a safe recovery! I was nay goin' t' tempt fate with another launch. One thin' I would say, t' rocket really needs 18” chutes minimum. Well, blow me down! While t' landin' did nay cause any damage, ya bilge rat, I did wince as it looked rather hard. Ahoy! However, I had to live with what I got – t' 12” chutes.

Summary:
This was a great contest that challenged me. Despite all me JINXes, I think I came up with somethin' special that used almost all o' me parts. Well, blow me down! I guess t' only thin' I didn't try is puttin' t' rest o' t' parts into a blender...
