Traveller: stopper knot or bowline or clamp or ...

I am rebuilding the traveller system on my older Windward 28.

The original owner started with a good track and a good cart but then used pulleys too small and mounted them at dumb angles that foul on everything. The result is high friction; you have to PULL to adjust things.

Since I have some modest machining capabilities, the redesign has been a relatively easy fix.

The last decision to make is how to fasten the fixed end of the line.

A spliced eye through a padeye is the nicest option, but now you lose some travel in an already short track as the thickness of the splice won't enter the pulley.

A bowline through a padeye is another option, and what I'm leaning towards but it's .. inelegant .. AND the sharp bend would seem to stress the line.

A stopper knot through a padeye JUST the right size would seem to have a less sharp bend at the critical point but I worry about the knot holding.

Finally, I could just clamp the line, squishing it between two plates. If it were a piece of metal, I would have no hesitation doing so. But as I've NEVER seen this strategy used with line, I'm more than a bit hesitant.


Any thoughts or opinions appreciated.


Alan

A stopper knot should work fine, I'd use a double overhand.

I bowline the ends on my padeyes just because I dont want the line to go either way. (not that it's likely under tension, but well).

A stopper knot or a simple figure eight knot will work just fine - it's what they were created for.

Yep, I scrolled down this thread to see if someone pointed out the Ashley stopper. It's closest to a sphere and larger than the other knots so it maximizes it's cross section for stopping (as opposed to the figure 8 which is oval in the wrong direction). I think the double overhand is the cleaner looking knot but the Ashley should be the best at stopping.

Thanks to all!

I have an idea for a big stopper knot that I can bury inside the pulley block (to keep everything tidy) that's also clamped on the free end so it can't worry itself loose.

I may be going a bit overboard here (if you'll pardon the pun), perhaps over thinking trivial details, but it's been my experience that bad things never seem to happen at convenient times ...

Don't forget it's only a traveller control line - it's not like something big is going over the side if the knot comes undone.

Alan, Selden uses that method to attach the furling line to their Furlex furling systems. I don't see why it wouldn't work fine for a traveler control line termination.
They have a small aluminum plate with a screw in the middle. The line is circled around the screw 180 degrees and then the plate is screwed tight to the inside of the drum. The plate also has raised ridges that help grip the line.
Some variation of that method would probably be a very elegant way of solving your problem.
