After talking about the fairleads I got to thinking maybe I'll try and make one, so I fettled one out of two pieces of styrene profile glued together, well I thought it came out ok, then I thought about the moulding of it, to make a mould of it standing upright would need to be a split mould due to the nature of the hole, I felt this was a bit complicated for such a small fitting, of course I could fettle all eight of them but I doubted I could get them all identical, it then dawned on me it could be moulded laid on it's side, which is what I did, and the first one has just been done, after sanding off the excess resin, I think I have some passable fairleads that are actually stronger than I had thought.
