Assembly:

Bottom Section

1.    Cut t' lip off one o' t' Styrofoam cups.
2.    Make a mark 1 1/4" from t' bottom o' t' cup and cut.
3.    Drill a 1" hole in t' base o' t' 2nd cup. Avast, me proud beauty!
4.    Mark it 2" from t' bottom and cut. Save t' bottom half.
5.    Usin' a 1" Forstner Bit drill a hole in t' Acrylic Sheet.
6.    Find t' center o' t' hole and, usin' a 2" hole saw bit, ya bilge rat, drill around t' hole, makin' a centerin' ring.
7.    Place t' new centerin' rin' in t' bottom half o' t' 2nd cup until it's tight. Begad! Then make a cut so t' cup is flush with t' centerin' ring.
8.    Glue t' centerin' rin' into t' cup.
9.    Cut 1/2" from t' burned out engine. This makes t' centerin' ring. Avast, me proud beauty!
10.    Glue it into t' BT-50 body tube until it's flush.
11.    Glue t' body tube into t' acrylic centerin' ring. T' body tube's engine block end should be flush with top o' t' acrylic centerin' ring. Begad!
12.    Drill a 1 3/4" hole in t' cardboard
13.    Find t' center o' t' newly drilled hole and, usin' a 2 7/8" hole saw bit, drill around t' hole.  Makin' a larger centerin' rin' than t' acrylic one.
14.    Glue t' cardboard centerin' rin' into t' lip o' t' 2nd cup. 
15.    Apply a bead o' glue t' inside o' t' cardboard centerin' ring. Then, shiver me timbers, place t' BT-50 tube with t' centerin' rings into t' cardboard. Avast, me proud beauty! T' body tube should stick out o' what would be t' top o' t' cup. This will make t' bottom portion o' t' cup, (in t' tube's centerin' ring,) fit snuggly into t' hole in t' cardboard. Avast, me proud beauty!
16.    Glue t' first, shiver me timbers, taller, shiver me timbers, cup onto what you just glued. T' wider part o' t' cup should fit somewhat into t' 2nd cups lip. 
17.    Glue t' toilet paper tube t' t' top o' t' bottom portion. Avast, me proud beauty! It should fit right on top o' t' acrylic centerin' ring. Avast!
18.    In t' balsa, ya bilge rat, drill a 1 3/4" hole.
19.    Find t' center and, usin' a 2 1/2" hole saw, matey, drill around t' previous hole. As you might have guessed this creates a balsa centerin' ring. Ya scallywag!
20.    Sand t' balsa centerin' rin' down at a slant.
21.    Glue around t' toilet paper tube and around t' top o' t' bottom section. Slide t' balsa centerin' rin' on.

Nose Cone

1.    Mark t' 18" side o' t' posterboard at 9".
2.    Cut a piece o' yarn about 19" long.
3.    Tie t' yarn into a loop. Avast, me proud beauty! It should be able t' reach t' other side o' t' paper without goin' over. Blimey! If t' loop is too long or too short, you may have t' play around with t' length. Avast!
4.    Put 2 pencils in t' loop and pull apart. Blimey! Place one pencil at t' 9" marker, me bucko, and hold it thar tight.
5.    With t' other pencil, matey, try t' pull away from t' 9" marker and let t' pencil draw a semi-circle.
6.    Cut out t' semi-circle.
7.    Form t' semi-circle into a cone so that t' base is 3" in diameter and t' top is 1 5/8" in diameter. Then tape t' cone t' hold it in place.
8.    Usin' a can o' 3M Super 77 Multipurpose Adhesive spray glue, coat t' inside o' t' cone with glue, creatin' somewhat o' an airtight seal.  Let it dry.
9.    Cut t' water bottle off 2 3/4" from t' top or until it starts t' curve inward t' form a hand hold.
10.    Cut out t' pour spout or t' part where you'd suck out water. 
11.    Drill a hole in t' lid just shy o' 1 3/4". Blimey!
12.     Cut t' base o' t' bottle off at 1/8". 
13.    Drill a hole 1 3/4" in diameter in t' piece o' bottle you just cut off.
14.    Make a centerin' rin' from t' one inch sheet o' Styrofoam. Ahoy! Drill t' first hole 1 3/4" in diameter then make t' outer edge's diameter 3".
15.    Glue t' centerin' rin' onto what used t' be t' base o' t' bottle. Ya scallywag!
16.    Glue t' base o' t' bottle t' what used t' be t' top o' t' bottle. Avast, me proud beauty! Blimey!
17.    Glue t' cone you made earlier onto t' top o' what be t' base o' t' nose cone. Make sure t' cone is stickin' straight up.
18.    Glue t' BT-40 tube into t' top o' t' cone. Ya scallywag! Make sure it's straight as well.
19.    Now cut t' sheet o' copy paper in half length wise.
20.    Roll half o' t' copy paper into a cone. Well, blow me down! T' tip should come t' a point and t' base should be about 2" in diameter.
21.    Make two centerin' rings out o' t' particle board t' outer diameters should be 1 5/8" while t' inner diameters should be able t' fit snuggly around t' BT-50 tube.
22.    Glue t' centerin' rings onto t' top and bottom o' t' BT-50 tube. Ya scallywag! T' top rin' should be 1/4" o' an inch away from t' top o' t' tube.
23.    Glue t' pointed cone t' t' top o' t' body tube. Begad! T' centerin' rings should fit into t' BT-60 tube loosely and t' pointed tip o' t' nose cone should fit over t' top o' t' bigger cone you made earlier.

Fins

Honestly, makin' t' fins is a lot o' guess work, but here is how I was able t' do it:

1.    Go t' t' EMRR website and copy t' picture o' t' rocket you're tryin' t' replicate. Avast, me proud beauty!
2.    Crop t' picture down enough so that you only see t' fins.
3.    Play around with different sizes. This is a lot o' t' guess work. Avast, me proud beauty! You have t' play around with t' size, me hearties, and then print it t' see if it's t' right size. Ahoy! If it is, shiver me timbers, t' root length for t' top fin should be about 1 1/4" and t' bottom fin's root length should be about 1 1/8".  T' top fin should stick out 1 1/4 inch and t' bottom fin should stick out about 1 inch. 
4.    Cut out t' fins t' make a pattern for t' top fin and bottom fin.
5.    Trace t' patterns on t' t' 1/4 inch o' cardboard. Blimey! Make 3 shapes for each fin so you end up with 6 fins.
6.    Cut out t' fins. Well, blow me down!
7.    Glue t' top fins on t' t' toilet paper tube so that t' bottom touches t' balsa rin' above t' polystyrene cup. Begad! Make sure it's stickin' straight out. Avast, me proud beauty! Then glue t' bottom fin so that t' top is touchin' t' lip where t' two cups came together. Ahoy! Make sure t' fins are lined up with each other.

Now t' make t' pods that are connected t' t' fins.

8.    Glue t' three balsa nose cones into t' three 2 3/4" BT-20 tubes.
9.    Cut 1/4" off from t' top o' t' tube. Ya scallywag! Sand it until flat, if necessary.
10.    Glue t' 1/2" Wire Connectors onto t' nose cone.
11.    Stick t' 1/4" dowel in a hand pencil sharpener. Ahoy! Once pointed cut off point at t' base o' t' tiny cone. Repeat 2 more times. Avast, me proud beauty!
12.    Glue these tiny cones t' t' tops o' t' wire connectors.
13.    Take t' BT-5 tube and wrap maskin' tape around t' top o' it until it fits into t' BT-20s. Blimey! Blimey!
14.    Glue t' tubes in. Blimey!

Overall: Glue all pieces together. Begad! Add a straw for t' launch. 

Paint t' rocket. Begad! Make sure t' primer on t' base o' t' rocket is free o' acetone or any other paints with acidic qualities. You have t' do this or t' paint will eat right through t' polystyrene base.  I find that your typical craft paints work very well.

For t' Recovery system I used an 18" parachute.

Flight Log:

• Date    10/29/10
• Motor    Estes D12-3
• Ejection/Altitude     80 feet
• Wind 5-10 MPH

Notes: Prototype- First Flight. Unstable. Aye aye! T' problem lied in that t' fins were nay glued on straight. Aye aye! Still has a possibility o' flying. T' model I had on RockSim worked and was stable.

Status: Irreparable 

Note: Crooked Fin
