Help me find a stanchion top?

Sounds like it should be suitable.

Our Nylon Rod is a superb wear and abrasion resistant material and well suited to machining. Nylon Rod has high mechanical strength and good sliding ...'

It will also swell slightly when wet and tighten the grip.

Just to finish off the thread, some photos's:

These are the 4 good ones that I removed. These fitted over the outside of the top of the tubes http://rfelectronics.webs.com/Frolic18/stanchion_tops.jpg

And this is one of the new ones I made. This instead is a solid bar, turned down to fit inside the tube, much neater and easier to make http://rfelectronics.webs.com/Frolic18/new_stanchions.jpg
