Brief:
A while back, shiver me timbers, I saw a couple o' oddrocs made from wooden birdhouses from Michael's Crafts. Well, blow me down! I was inspired and bought a couple, one hexagonal and one round, ya bilge rat, at a 2-for-1 sale. Ahoy! This article will describe t' hexagonal version, which will fly on 29mm G motors.

Construction:
T' parts list:

• One hexagonal birdhouse
• 29mm motor mount
• Spent 29mm casing
• Two 6-32 bolts with nuts and washers
• 3/16 plywood scraps
• ¾" pine strip
• Two rail buttons
• Lexan
• 3/8" elastic
• Keelhaul®©™twine

Construction started by carefully pryin' t' roof o' t' birdhouse off. Aye aye! This naturally serves as a nosecone, me bucko, however, it lacks a shoulder. Aye aye! I decided t' run t' motor mount t' t' top o' t' "cone" and use a chunk o' a spent 29mm motor as t' shoulder. T' chute would reside beside t' motor tube and would be protected from t' top by a chute pad.

I drilled a hole in t' base usin' me Harbor Freight drill press and a suitably sized wood bit. Avast! T' center was easy t' find by drawin' lines from opposite corners. Well, blow me down! I also drilled holes for t' bolts that would serve as mountin' points for t' motor clips.

Next I glued t' mount in place, checkin' that it was vertical by measurin' t' distance t' each corner. Ahoy! Aye aye! I used 5-minute epoxy throughout so t' build would go fast. Aye aye! Ya scallywag! T' Keelhaul®©™leader be inserted betwixt t' motor tube and t' body and was wrapped around t' back o' t' tube.

T' base is thick (3/8") but t' motor tube still needs some additional support. Begad! Aye aye! I cut two vertical braces that fit betwixt t' mount and wall o' t' body, matey, and which are about half t' depth o' t' cavity.

T' attach t' piece o' casin' (bottom 2"), I inverted t' cone and filled t' tip with epoxy. Begad! With t' casin' inserted all t' way into t' motor tube, I placed t' body on t' cone and made sure it was seated securely. Ya scallywag! I then used a dowel t' push t' motor casin' down into epoxy puddle. This ensured its alignment. Arrr! I also epoxied a piece o' elastic onto t' tip o' t' cone (actually 2 pieces tied together--this be a "use what ya got" project).

I recently found that with proper care and a diamond cut-off disk in your Dremel, arrr, me bucko, you can cut Lexan pretty easily so I whipped out three fins that extend below t' body by about 5 inches. Ya scallywag! This overhang was based on what I remembered about t' proven designs I had seen earlier. T' bottom rim o' t' birdhouse, which protrudes from its base, me bucko, was notched t' accommodate t' fins. Begad! Blimey! T' fins are also attached and heavily filleted with epoxy.

A thick piece o' pine was required for t' rail buttons t' clear t' cones overhang (I guess this overhang would technically be t' eaves.) This could have been narrower, matey, shiver me timbers, but since t' overhang mostly occludes it and I'm nay goin' for altitude, shiver me timbers, it sufficed.

I modeled t' hexagonal structure in Rocksim 8 usin' circular parts whose diameter be t' average o' t' short and long dimensions o' t' actual rocket. Blimey! Blimey! I also plugged in t' actual weight and CG. Ahoy! My ace in t' hole was knowin' someone who had proven rockets based on t' same product. Ahoy! I added nose weight and ended up with a static margin o' 2.0. Aye aye! This seemed tight, but t' Birdhouse will have a ton o' base drag.

Finishing:
Finishin' consisted o' a couple o' coats o' Minwax Polycrylic. Avast! I also brushed on some Helmsman spar urethane over t' fillets so exposure t' UV wouldn't yellow them.

Flight:
I used a 36" nylon parachute, me bucko, which I attached t' a loop in t' shock cord. Avast! It was placed in t' nose and covered with dog barf wadding. Avast! I flew t' Birdhouse on a F52-5T. Blimey! It weathercocked a little and ejection be just past apogee. Begad! T' next flight will be on a G79 or G77.

Recovery:
T' 36" chute spared t' Lexan fins.

Summary:
What's thar t' say? This is a unique, me bucko, matey, matey, inexpensive rocket that is sure t' get people’s attention. Avast! Ahoy! I need t' get an ornamental bird t' place in t' "door".
