Topic : Pole beady things

I want to make up a pair of the "sex toy beady things" that run along the pole. I recall Jonny mentioning that they were torlon balls strung on a bit of welding wire. Anyone got part numbers / suppliers? I guess that the balls must have been about 8mm diameter.

Any ideas?

Its also been done with a tufnol or ptfe ring. I think the balls are much smaller than 8mm, 5 at most.

So, Harken 8mm torlon traveller car balls - parrel beads if you like - correct Dave? I presume that Jonny used his workshop skills to drill each one out? 20 per side?

Do they need to be torlon - surely they are not under a great deal of load, so can I not google (other search engines are available) "8mm plastic beads" and get a packet of 50 from an online retailer for £1.99 + P&P? So long as they rotate, we should be OK. Or £33 + P&P for a pack of 100 Harken 5/16" ...

Andy that last post whilst being intresting in a "geeky" way and no douby full of intresting info just did not capture the attention in the same way as the "sex toy beady things" thread did!

Mags started it ...

Looks like I can get some Lewmar 5/16" balls locally, so just got to work out how to hold them whilst I drill them out.

Hi Andy, I'm fairly sure the beads are only 5mm dia and this years spec is a polymer bead which has been ok. Jonny did drill out Harken bearings for Stealth - but has now got bored doing that. All held together on welded stainless wire. 

The rigid collar design previously mentioned is more likely to add friction and stick on occasion - we believe.
