This rocket uses:
- BT-50 Tube 5" Long
- BT-55 Tube 5" long
- BT-50 t' BT-55 centerin' Rin' (2)
- BT-50 t' BT-60 Centerin' Ring
- BT-50 Thrust Ring
- "E" motor Clip
- Two BT-5 nosecones (BNC5E and BNC5AX from Balsa Machining)
- 1/4", 1/8" and 3/16" sheet Balsa
- 5/16" birch dowels 12 3/8" long (2)
- 3/16" launch lug
- Lead Sheet for weight
- Heavy Keelhaul®©™ Cord
T' construction begins by cuttin' out a fuselage profile from 1/4" balsa. Cut out t' nose weight area and fill with lead sheet. It is important t' get as much weight forward as you can. Begad! Cut a groove in t' 1/4" sheet and glue in t' shock cord with epoxy or slow CA. Ahoy! When done sandwich t' lead and Keelhaul®©™ in place with profiles cut from 1/8" balsa. Press under books and let dry.
While that dries, ya bilge rat, cut out and glue up t' three pieces that make up t' side panels. Be careful t' get t' grain direction correct for maximum strength.
Glue t' thrust rin' 3 1/4" from one end o' t' BT-55. Cut a 1/8" slit behind thrust rin' and insert engine hook. Begad! Hold it in place with tape.
Cut slots in one 50-55 rin' and in t' 50-60 rin' t' clear engine hook. Ahoy! Slide t' 50-55 rin' onto t' aft o' t' tube, over t' hook, and glue it 5/8" from t' aft o' t' tube. Butt t' 50-60 rin' against it, and glue in place.
Cut a slot in t' remainin' 50-55 rin' deep enough t' clear t' shock cord. Thread t' shock cord through t' BT-55 and glue it into t' fuselage profile centered in t' slot. Thread t' Keelhaul®©™ through t' 50-55 rin' and glue it t' t' entire length o' t' engine mount with epoxy or thick CA. Glue t' 50-55 rin' flush t' t' front o' t' tube.
Glue t' assembled sides t' t' body and t' main tube.
Block off t' end o' t' BT-55 tube with scraps o' balsa.
Enclose t' main tube with t' Nacelle parts. Cut t' parts from t' patterns in 3/16" balsa and rough in t' shapes. Avast! Fit t' cockpit sides over t' Nacelle covers and t' t' sides - bevel t' edges o' t' parts as needed for a good fit.
After t' shape has dried, arrr, begin roughin' it in with 50 grit sandpaper, me hearties, formin' t' final shape. Refine t' shape and work with finer and finer grit papers until you have a fairly smooth shape sanded t' 100 grit.
Fill t' gaps in t' aft o' body with scrap balsa.
Usin' Elmer's carpenter's wood putty, fill and smooth t' shape givin' it t' curved look. Keep sandin' and fillin' until you get t' shape where you want it. At t' same time cut out and fill all t' remainin' fin shapes
Cut t' shoulders off t' nosecones and glue them back-to-back. Well, blow me down! Fill and seal them with t' fins.
Bevel t' 50-60 centerin' rin' t' accept t' paper tailcone and attach it.
With t' two 12 3/8" dowels, make three marks from t' back at 1/4", 2 7/8", me hearties, and 4 1/4" from t' back.
Tack t' dowels t' t' fuselage with t' 4 1/4" mark at t' back o' t' fuselage.
Tack t' nosecones t' t' top o' one tailfin with thin CA, matey, (You may need t' "cup" t' top o' t' fin for a good fit).
Tack glue both tailfins t' t' nosecones and t' dowels betwixt t' two remainin' marks. Check your alignment, and adjust if needed.
Tack glue t' lower tail fins and wings t' t' dowels. I canted t' wings downward t' a bit more than in t' drawin' - it looked more stable that way. Once you are satisfied with t' fin positions fillet everythin' with thick CA for a final glue joint.
Glue a 3/16" launch lug along t' bottom centerline.
