This is the third time the knotted bungee and cap have come loose from the pin.

viz: https://picasaweb.google.com/1081497986 ... 7707267202

I am guessing that my sin has been not removing the pin before flipping the hull on it's side to remove the wheels - subjecting the pin to a certain amount of twisting..... At least the slightly-deformed metal in the wheel frame seems to suggest that...

But a press-fit of a steel pin into a plastic knob that gets subjected to repeated pushing/pulling/twisting seems to be a bad idea to me - and eventually my luck is going to run out and one or both are going to get lost in the failure process.

So...

  • Am I the only one?
    .
  • Has anybody got a more elegant workaround than a 6mm SS bolt ?

That has happened to me maybe four or five times over the last few years.

I actually keep a small-grade electrical wire handy to string down and pull the shock-cord up when it happens.

I keep thinking of epoxying the cap on but then I worry if the bungee wears out it will be hard to replace. So far I've just lived with it because it only seems to happen once a year or so. I definitely found hammering in the pin keeps it in longer than just pressing it.

Where I think I am going at the moment:

  • 6mm (or whatever size is small enough to fit and big enough not to slide out by itself) bolt
    .
  • String teather around bolt just below head, secured to the cargo bungee
    .
  • Hunk of foam glued to bolt shaft also just below the head - to keep teather in place and to mitigate bolt's sliding around once in place.

Actually, now that I'm thinking of materials at hand..... a section of bamboo (pretty tough stuff) chop stick and then as above.

I was more interested in whether I was the only one and/or others see a flaw in the press-fit design.

We have a new style pin that is now threaded into the cap. No longer an issue. Not yet in stock under the replacement pin part number as far as I know, do re-assembly and install with some epoxy for a fix. Try not to let the cap snap back into the tube when done with it,. The inertia can work the pin out of the cap.

I like that one better my theory...

Thanks.

I lost mine when it fell apart, I usually just look around for a stick now

Is it possible to order one of these to replace the old-style (non-threaded) pin/cap? Is there a new part number for it?

I can't tell if this is the threaded-type or not:
