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, arrr, and before I knew five o' them entered it as well. Well, blow me down! So off went a large box with t' parts for 6 entrants, and a few weeks later another box returned -it was like Christmas goin' through t' box. Next be t' task o' splitting op t' box betwixt t' 6 entrants. Ya scallywag! At t' end 6 "equal" bags were formed and randomly given out. Begad! I be quite pleased with me bag, arrr, others had complete rockets in the, one had a parasitic glider, me hearties, another had helicopter rotor blades. Blimey! Avast! 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, shiver me timbers, ya bilge rat, helicopter be a possibility, me hearties, cluster, matey, two stage. Well, blow me down! After spendin' several weeks dry fittin' parts and changin' me mind I decided on a rocket in me head. T' criteria for me rocket was
T' main body tube chose itself - it fitted t' nose cone I wanted t' use. Avast, me proud beauty! T' motor choice be goin' t' be 24mm as I was headin' for a draggy model, so I would need a motor capable o' liftin' it. Ya scallywag! Ya scallywag! There be goin' t' be at least 4 external motor pods - opted for 13mm. Blimey!
T' base be goin' t' be bulky, and was goin' t' have tabs on it, so t' rocket would rotate as it boosted.
Building
|
T' motor mount was a fairly standard construction. Avast! 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. Blimey! These were t' take 4 A10 - PT motors as a cluster. Avast! Blimey! T' joins betwixt t' body tubes were filleted four times with wood glue, and then model filler was used t' give a smooth finish. Avast! T' shock cord was anchored t' t' body tube usin' Estes tri fold paper method - I was tempted t' cheat and add some Keelhaul®©™ here, matey, but integrity got t' better o' me. |

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

Usin' a strip o' thick balsa, me hearties, 7mm by 26mm, I made a box around a large coupler. Ya scallywag! Blimey! Aye aye! Blimey! Blimey! Blimey! This box was goin' t' have the fins and rotation tabs added. Arrr! Blimey! Blimey! Blimey! T' balsa was quite badly marked and be t' soft type o' balsa that I usually avoid. Ya scallywag! Blimey! The box was sanded several times and filled with model filler t' remove all o' t' dents. Aye aye! Blimey! Blimey! 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! 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 be just right size t' side over t' body tube. Begad! Blimey! Begad! Blimey! T' spirals were filled and had t' have several coats o' sanding sealer before it was smooth. |

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

T' corner spaces betwixt t' box and t' couple were just t' right size for body tubes, matey, which were added for decoration. 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. Avast, me proud beauty! Well, blow me down! These were t' provide spin. Well, blow me down! |

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

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

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