non slip rubber - what is the non-slippiest?
 
I do a bit of windsurfing and the masts have got narrower over the years. I have an adapter that goes on the mast and then the clamp on the boom clamps to the adapter. Unfortunately the adapter is made from a fairly hard plastic and the joint slips.

It is just a round pole with a round clamp, the clamp is oversize.

I want to make my own adapter and had a look on ebay.
I saw two possibilities.
Silicone sheet and reinforced conveyor belt, both at 6mm thick.

Any thoughts for a good material which will not let the clamp slip down?
thanks

non slip rubber - what is the non-slippiest?
 
The trouble is that the non slippiest tends to get itself coated in stuff
and is then not so non slip like the material in those non slip mats, which
you can get on a roll, and its wonderful when new, but...
So is the problem up and down slippage or rotational?
I would have thought it should rotate, but not move up and down, in which
case some kind of araldite on rings top and bottom would seem to be needed.

Is it because the fits aren't good and if they were, all might be
well?

I have 3D printed all sorts of 'split collars' to overcome that sort
of thing and they have worked very well.

If you had an accurate OD, ID and assuming the width was no wider than
about 150mm and the OD (inc any flange) was less than 200mm, I might
be able to help?

Cheers, T i m

Up and down slippage is the problem

Some Dycem bought.
Hopefully no swearing at the clamp next time I am out.

Not quite sure I follow (as another poster has said). Is it that the
boom slips down the mast? Is the boom expected to have freedom to rotate
about the mast or not? Or does the mast rotate at the board joint.

If you have rubber and a reasonably tight clamp I would not expect it to
slip, so no need for the tacky no-slip materials like Dycem or those
little mats you can use to stop mobiles from sliding around on the
dashboard. Best if it is clamped up dry, of course. I'd go for a softer
rubber that will adapt better to surface roughness than, say, reinforced
belting. Something like inner tube material? Some things will be more
ozone and UV resistant than others but if it is going to be replaceable
that doesn't matter so much.

Googling "windsurfer boom clamp" seems to throw things up for a tenner.

Bit of bicycle innertube? Free at bicycle shops, not much more new.

I have tried the bike inner tube, and the tyre too, both slip. I have also bought an adapter made for the job, and it slips easily.
The tyre is the best so far, but it still slips quite quickly.
I have a friend with a printer Tim, I'll ask him if the Dychem slips.

You could try mounting it with double sided sticky tape, as used for golf club
grips?

This is how it's done for golf club grips: sticky tape stuck to shaft, peel off
outer protective tape, exposing outer sticky side. Coat tape with solvent
(white spirit, Stoddard solvent, naphta, special solvent, ...) and also use the
solvent as a lube inside the rubber grip. Slip the grip over the sticky tape,
which is now not sticky because of the solvent. The grips are generally a very
tight fit, and it will work easily *if* there's enough solvent, and if it dies
up or gets wiped off, the grip may get stuck halfway on. Then, let dry: the
solvent evaporates eventually (overnight to 24 h), the stickyness returns,
fixing the grip in place. This is pretty permanent: the usual method on removing
the grip is to cut it with a knife and peel it off. See youtube for more...

I expect that a tight-fitting tube slipped on forcibly would hold better than a
tyre, which is open, but that's just a guess.

Sounds like it is not clamping tight enough. Presumably it has to be
removable, so can't be "glued" solid? Perhaps if you glued one layer of
inner tube to each part so that you are then clamping rubber to rubber?

Remember that inner tube is lubricated with talc to stop it sticking. I
would try to clean it by scrubbing with detergent, then abrading with
sandpaper to improve the key.

Np.

I it seems there isn't a day goes by when I don't design and print
stuff these days. Things that I could possibly fabricate from wood or
steel or turn but it's a darn sight easier to print. ;-)

Yesterday, whilst waiting for a bracket to print, I designed little
retainers to stop rowlock crutches accidentally coming out of their
rowlocks (as I can't seem to find the commercial ones any more).

I finally went out on the windsurfer last night. I wrapped the Dycem matting around the mast and used it to match the diameters.
Flipping Brilliant, no slip at all.
Thanks all.
