Colin has polished the line slots on our shafts using some grinding paste and nylon cord, it has reduced the chaffing loads but the outer case of the dyneema still wears but the inner strands are fine for ages afterwards so generally no problem. The dyneema whishbones are made up just like Huan explained except we reuse the small washers as well (not sure if it is any advantage or not). Anyway the point I was trying to make was to check these washers out if you use articulated wishbones as an extra bit of kit check that might not usually be looked at.
