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.

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