Hi, I am looking to upgrade my i14 to self tacker and was wondering if any one has an old track or slider (or both )
or knows of any one who has come up with cheaper ideas - I was thinkin
maybe a stainless steel rod (3-5mm thick) with a pulley run on it
connected to the jib pulley - i know it would slide well its just
whether it will sheet to the correct angle!If any one has some old track or sliders, or any information on other self tacker systems it would be very helpful!! ------------- Any one in need of quality carbon fibre work (tillers etc) at decent prices!

Oh yeh i forgot to mention - I can get the sliding track of an old dart
real cheap with the slider - does ne one know if a mainsheet
slider/tacker would work or is it 2 chunky to be worth while?

Be a big lump the mainsheet one. Probably more friction too.
One tip, if at all possible get track without any holes in. If you have the usual pre drilled track when you bend it to shape it tends - of course - to bend most where the holes are,and you end up with a ratchet jib track which is less than desirable. |

Thanks for that jim c, unfortunatley the dart track is predrilled so its an unlikely option now! ------------- Any one in need of quality carbon fibre work (tillers etc) at decent prices! Int 14 Gbr 1244 'Nucking Futs' The New Port rule!!. |

I wonder if instead of a track a strop (like a mainsheet strop) would work? ------------- Garry Lark 2252, Contender 298 www.cuckoos.eclipse.co.uk |

Yeh it would work but only straight across a boat - it cannot be curved
because it would need support - I am currently looking at using
stainless steel rod to the same effect but it can be bent thus being a
no go grab rail!! ------------- Any one in need of quality carbon fibre work (tillers etc) at decent prices! Int 14 Gbr 1244 'Nucking Futs' The New Port rule!!. |

When my Self tacker track broke I replaced it with a peice of aluminium tube which had previously been a cloths rail. With a U bolt as a slider.
It worked for a few days but tended to bend in the middle quite a bit. and had too much friction.
------------- If it doesn't break it's too heavy; if it does it wasn't built right |

| what kind of 14 do you have? mate tried the cloth trail, but it relly didnīt work very long, even in our light winds. |

Ive got a benedict 7 hull thats been modifyed by ovington and has
extended wings(racks like the new ones but solid like a 49ers), and a
prodder. It currently has a spaceframe with a open foredeck but we are
in the process of replacing that with a carbonkevlar fibre foredeck. I was wondering if a system along the ideas of the clothes line but using solid steel rod in stead of soft aluminum clothes line would work! - its certainly hard enough to bend into shape! How do you mean bend in the middle surely there is hardly any sheet tension as the sail passes from side to side? ------------- Any one in need of quality carbon fibre work (tillers etc) at decent prices!

Sargethesailor, I prefer to describe it as recycling. It is a skill I learned rebuilding some rather tired Laser II's Did you happen to study in the granite city yourself? The clothes rail only lasted a few days before it was replaced with a proper track. 
I would definatly agree with Jim C's comment that you should try and get a track that is not pre drilled. It is difficult to bend the track without gettng kinks. ------------- If it doesn't break it's too heavy; if it does it wasn't built right |

Part of the problem was that the slider was just a U bolt it would stick during a tack and would not go right to the end. Also the sheeting point was in board of the outer attaching point so it would twist the whole thing under load so that the center point of the track would lift up slightly. The Aluminium tube it was made from was verry soft I just bent it over my knee, Stainless steel would be alot stiffer if heavier. You would need to make the attaching points quite strong to resist all the twisting loads, remember that as the lead for the sheet is turning through nearly 180 degrees the track takes almost double the sheet load. ------------- If it doesn't break it's too heavy; if it does it wasn't built right |

Thanks very much for that info granite - it should hopefully just be a solution until i sort out the front deck and its track!
