Flight Registration Form
by Adrian Hurt

Background
Near t' end o' this year's International Rocket Week, various odd, nay t' say silly, rockets were built. Ahoy! After ponderin' for a while on how t' contribute t' t' silliness, I decided t' act on somethin' I'd overheard earlier in t' week. Aye aye! I'd make a rocket out o' a flight registration form. Ahoy!

Construction
Each rocket flight at t' event had t' be accompanied by a form which was filled in and handed t' t' range safety officer (RSO) prior t' launch. Begad! There were plenty o' spare forms, so I took one and filled it in. Begad! Arrr! Blimey!

A large area at t' bottom o' t' form is intentionally left blank, as the sayin' goes. This was cut off. A half circle cut and rolled from this piece became t' nose-cone; another piece, arrr, arrr, formed into a cylinder, became t' cone's shoulder. Well, blow me down!

T' rest o' t' form became t' body tube. Blimey! T' left side o' t' form be the tail end. Begad! Aye aye! Three equidistant lines were marked, then cut out as fin location slots. Begad! Avast, shiver me timbers, me proud beauty! T' top margin, bein' blank, became an overlap for glue. Avast!

Three fins were cut from a piece o' suitable size balsa that happened t' be available. Aye aye! Arrr! A motor mount was made from a spare piece o' BT-20, shiver me timbers, with a thrust rin' made from about 1/2" cut from a spent 18mm motor casing. Centering rings were cut from cardboard, arrr, but these were only for centerin' and sealing; the fins had tabs extendin' t' whole way t' t' motor mount tube. Avast, me proud beauty! T' fins, rings and tube therefore became a complete fin can which was glued into the rear o' t' body tube. Begad!

A fabric elastic shock cord was attached t' t' body and nose-cone usin' two Estes-style folded paper mounts. Avast! A launch lug made from a piece o' drinking straw was glued t' t' body, ya bilge rat, aligned along and attached t' t' seam where the form had been glued t' make t' tube. Ahoy! A good dollop (real precision measurement here - not!) o' plasticene in t' nose-cone put t' CG safely forward, and with a C class motor installed, t' rocket passed a swin' test. Begad! Begad! (Bear in mind that this be at a rocketry event, so I did nay have access t' me computer. Begad! In the absence o' VCP, shiver me timbers, I had t' resort t' t' old way o' checkin' stability!)

Flight

Before puttin' t' rocket on t' pad, I had t' show it t' t' RSO, of course. Ya scallywag! Avast, me proud beauty! This was part o' t' fun; when he asked for t' rocket's flight registration form, I pointed out that it was t' flight registration form! Blimey! (Of course, for formality and for t' records, shiver me timbers, me hearties, I also had a duplicate, more conventional form!)

It be after t' rocket be on t' pad that I finally decided that t' balsa used for t' fins be too thin and flexible. Begad! Well, matey, blow me down! So t' prevent t' fins from flexin' or shreddin' in flight, I cut broad reinforcement strips from t' same balsa and glued them t' t' port, matey, or anticlockwise, side o' each fin. This final construction detail was actually carried out on t' launch field! The reinforcement strips were aligned so that their grain ran across that o' the main fins, thus creatin' a cheap'n'dirty plywood. Begad!

T' rocket carried an Estes C6-3 t' send it up, and a big mylar streamer to brin' it down. Begad! It flew well enough and landed safely back in t' launch field. Unfortunately, ya bilge rat, shiver me timbers, I had filled in t' form usin' a ball-point pen, so I can't change t' details for t' next flight. Avast! Aye aye! (Unless I use Tipp-Ex...)
