Not a common topic on a boat, I know, but I suffered the indignity at the weekend of having the wheels fall off my SIB
Launching wheels, that is.
Having taken lots of advice on this forum regarding launching wheels I invested £80
but the ironmongery was stainless, nice big, soft, rubber wheels, the whole lot swings up and down easily, or is easily detached if required. Perfect. Sort of.
The wheels are held on to the stub axles with washers that have a serated tooth arrangement to the internal diameter (I'm sure someone will come along and tell me what they're actually called). You put the wheel onto the axle, press the washer on and, in theory, hey presto. What's supposed to happen is that any sideways loading from the wheel causes the washer teeth to dig in and resist. Nope. Wrong. Not in this case, anyway.
The washers are not symmetrical, so they have to go on the right way as the teeth are angled along the axis of the washer. In so being, again, the theory is, easy to put on, hard to take off.
The washers are plated mild steel and the axles stainless. And there, I think, lies the problem. The mild steel teeth won't dig into the hard stainless and just slide. In 200 yards the wheels came off about 10 times
The language was awful
I'm about to convert to thrust washers and Beta Clips.
Moral...check before you buy

Codders...as an aside, this type of wheel is still the dogs
