Just an FYI, saw some gouges, mostly light, but one deep, on the inside of my boom extension, was coming from the screw end projecting out of the Chinook outhaul pulley. Decided to cut screw off flush with an angle grinder. Cut the screw end off from the assembled pulley and filed smooth, so when I disassembled the pully the nut made the threads correct.

The ones from Severne works much better.

Ahh, thought Chinook was the only maker, have one on every sail, will keep Severne in mind for any new sails, thanks.

I've just ordered a Chinook outhaul set. Haven't fitted it yet and never used one before. Thanks for the tip Sandman1221

Go to a ship chandler like Witworths and buy a shorter bolt.

You can also use acorn nuts.

That is a very thin looking grommet - no wonder. Just get shorter bolts, they are 1/4-20 US thread.

Why bother?, I just cut them down to the correct size!

I reshaped the plastic on mine more like teardrop shape like factory pulleys as well, much nicer as rope never gets caught & good purchase on doing them up/no serations on water logged winter hands. I also lapped the edges of the brass pulleys so the rollers don't bind if doing them up tight.

Unifiber do them also, prefer chinook as less bulky.
