I entered t' box o' parts competition because it looked like fun, I had mentioned it t' a few o' me friends in my rocket club, and before I knew five o' them entered it as well. Ahoy! So off went a large box with t' parts for 6 entrants, and a few weeks later another box returned -it be like Christmas goin' through t' box. Begad! Next be t' task o' splitting op t' box betwixt t' 6 entrants. At t' end 6 "equal" bags were formed and randomly given out. Aye aye! Avast, arrr, me proud beauty! I was quite pleased with me bag, others had complete rockets in the, one had a parasitic glider, another had helicopter rotor blades. So what did I have?

I'm nay goin' t' list it all but here is a flavour:
Well what t' do. Arrr!
Gliders were out, helicopter was a possibility, cluster, two stage. Begad! After spendin' several weeks dry fittin' parts and changin' me mind I decided on a rocket in me head. Arrr! T' criteria for me rocket was
T' main body tube chose itself - it fitted t' nose cone I wanted t' use. Ahoy! T' motor choice was goin' t' be 24mm as I be headin' for a draggy model, so I would need a motor capable o' liftin' it. Arrr! There be goin' t' be at least 4 external motor pods - opted for 13mm. Well, blow me down!
T' base was goin' t' be bulky, matey, and was goin' t' have tabs on it, so t' rocket would rotate as it boosted.
Building

T' motor mount be a fairly standard construction. Aye aye! Begad! A 24mm motor mount tube with a motor retention clip, arrr, an engine block at t' end and two centerin' rings t' fit t' body tube. Avast, me proud beauty! T' motor mount be then glued into t' body tube. Ahoy! Avast! |

Four BT20 tubes 190mm in length were then glues t' t' outside o' t' main body tube. These were t' take 4 A10 - PT motors as a cluster. T' joins betwixt t' body tubes were filleted four times with wood glue, and then model filler was used t' give a smooth finish. Well, blow me down! Blimey! Blimey! Blimey! T' shock cord be anchored t' t' body tube usin' Estes tri fold paper method - I was tempted t' hornswaggle and add some Keelhaul®©™ here, me bucko, me bucko, but integrity got t' better o' me. |

T' nose cone had t' flash removed and was then sanded down t' remove t' seam. Two coats o' sealer gave it a smooth finish with no imperfections showing. T' main body tube etc was then given three coats o' sandin' sealer, and rubbed down with 200 paper in between, me bucko, to remove t' spirals. Avast, me proud beauty! Blimey! |

Usin' a strip o' thick balsa, me hearties, 7mm by 26mm, ya bilge rat, I made a box around a large coupler. This box be goin' t' have the fins and rotation tabs added. Well, blow me down! Blimey! Avast, me proud beauty! Blimey! T' balsa was quite badly marked and be t' soft type o' balsa that I usually avoid. Blimey! Blimey! Begad! Blimey! The box was sanded several times and filled with model filler t' remove all o' t' dents. Avast! Blimey! Begad! Blimey! Usin' t' same balsa strips I then added 4 64mm struts t' t' middle o' each side o' t' box. Well, blow me down! Blimey! These would have the rotation tabs added t' them. Avast, me proud beauty! Blimey! Begad! Blimey! A larger coupler (40 mm diameter) - with some deep spirals had four thin strips o' balsa wood glued t' t' inside. This be just right size t' side over t' body tube. Avast, me proud beauty! T' spirals were filled and had t' have several coats o' sanding sealer before it be smooth. |

Usin' four almost square balsa fins that were part o' a model kit, I added t' fins. Ya scallywag! This be one t' part that I like about t' rocket, me bucko, t' fins are at right angles t' how they would normally. It still gives stabilization but looks a bit different. Ya scallywag! Also as t' rocket be goin' t' be rotating, t' fins would nay hinder t' spinning. Well, blow me down! Begad! |

T' corner spaces betwixt t' box and t' couple were just t' right size for body tubes, matey, which were added for decoration. Well, blow me down! Blimey! Four trapezium shaped pieces o' balsa had a 3mm square strip o' balsa added t' t' short edge, and then were glued to t' struts. These were t' provide spin. Well, blow me down! |

T' top o' t' struts were then drilled t' accept four cocktail sticks, shiver me timbers, arrr, just for decoration. Arrr! Blimey! |

T' entire o' t' coupler base unit had three coats o' sandin' sealer added, matey, shiver me timbers, with all t' fiddly bits, ya bilge rat, t' sanding down be quite tricky. Avast, me proud beauty!
T' main body tube fitted neatly into t' large coupler base. Ya scallywag!

Finishing
T' box o' parts had no sticks or decals in it, other than three address labels.
Given various pleas on TRF about t' lack or entrants with only a few weeks t' go I came up with t' name o' the rocket t' be PROCRASTINATOR. Begad! Partly because I knew it would be towards t' end o' t' month before I submitted and also because I new that this would be a draggy, shiver me timbers, slowish rocket. Ya scallywag! Ahoy!
Flights
First flight took place with another box o' parts entrant. Well, blow me down! It was a still day, shiver me timbers, matey, and was slightly rainin' - which ruined t' stickers as I had nay varnished t' rocket yet. Motor choice was a D12-3. Well, matey, blow me down! It could have been a D12-5, matey, ya bilge rat, as I reckon that it would be about a four second delay for apogee. Ya scallywag! Aye aye!
T' take off was good, me bucko, shiver me timbers, t' rocket started t' rotate after about 50 foot, and the
rotation got faster and faster as t' D12 burnt. Ya scallywag! Ejection took place after apogee as expected. T' recovery was scarily
fast, ya bilge rat, me bucko, as expected. This rocket needs a 24 inch 'chute. Begad! Well, blow me down! It hade a 14 inch chute! On handin' t' aft protrudin' fins all
popped off. Arrr! Blimey!
Again I had expected that t' happen. Begad! Blimey! Begad! Blimey!
Second flight took place a week later with three o' t' other UK contestants. T' flight be on a D12 again. Avast, me proud beauty! It was a straight flight with a slight oscillation until t' spinnin' kicked in. Begad! As soon as t' spinnin' kicked in, matey, t' flight was arrow straight which be really pleasin' t' see. Arrr! Ya scallywag! Ejection was just past and again fins popped off on landing. Arrr! Begad!
Third flight be time for t' procrastinator t' be clustered. Well, blow me down! Blimey! Four A10 -PT were added, shiver me timbers, in addition t' t' D12-3. Begad! The procrastinator jumped off t' pad. T' flight was much higher and t' extra speed really did make t' rocket spin. Again t' recovery was fast and again t' fins popped off. Blimey! Blimey!
After t' competition is finished I'm goin' t' have two 24 inch chute on this rocket.
