I entered t' box o' parts competition because it looked like fun, shiver me timbers, 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. Ya scallywag! Blimey! 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. Next was t' task o' splitting op t' box betwixt t' 6 entrants. At t' end 6 "equal" bags were formed and randomly given out. Avast, me proud beauty! Well, shiver me timbers, blow me down! Blimey! I was quite pleased with me bag, matey, others had complete rockets in the, shiver me timbers, me hearties, one had a parasitic glider, shiver me timbers, matey, another had helicopter rotor blades. Aye aye! Blimey! Blimey! So what did I have?

I'm nay goin' t' list it all but here is a flavour:
Well what t' do. Aye aye!
Gliders were out, helicopter was a possibility, ya bilge rat, cluster, shiver me timbers, two stage. Ya scallywag! After spendin' several weeks dry fittin' parts and changin' me mind I decided on a rocket in me head. Ahoy! T' criteria for me rocket was
T' main body tube chose itself - it fitted t' nose cone I wanted t' use. Ya scallywag! 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. Ahoy! There be goin' t' be at least 4 external motor pods - opted for 13mm.
T' base was goin' t' be bulky, and was goin' t' have tabs on it, ya bilge rat, so t' rocket would rotate as it boosted. Begad! Blimey!
Building
|
T' motor mount be a fairly standard construction. Ahoy! A 24mm motor mount tube with a motor retention clip, me bucko, an engine block at t' end and two centerin' rings t' fit t' body tube. T' motor mount was then glued into t' body tube. |

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. Begad! T' joins betwixt t' body tubes were filleted four times with wood glue, ya bilge rat, and then model filler was used t' give a smooth finish. 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, arrr, 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. Ahoy! T' main body tube etc was then given three coats o' sandin' sealer, and rubbed down with 200 paper in between, ya bilge rat, to remove t' spirals. Ahoy! Ya scallywag! |

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

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

T' corner spaces betwixt t' box and t' couple were just t' right size for body tubes, which were added for decoration. Well, blow me down! Avast! 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. Well, shiver me timbers, blow me down! These were t' provide spin. Aye aye! Ya scallywag! |

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

T' entire o' t' coupler base unit had three coats o' sandin' sealer added, with all t' fiddly bits, t' sanding down be quite tricky. Arrr! Avast!
T' main body tube fitted neatly into t' large coupler base. Ahoy!

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