F21 Halyard Sheaves

Posted by Charles Rush Arasim (crarasim@…>)

Does anyone know where I could get new sheaves for both my Main and
Jib halyards? And do you know the size of stainless steel pop rivets
I would need to get?

The sheaves are Harken #131 Big Bullet thru-deck.

The rivets are aluminum. Get 1/8" dia x 1/2" long. The mast wall is
1/4" to 3/8" thick. Get a good rivet gun while you’re at it. The
cheap ones won’t handle the big rivets.

Mike,
Thanks for the info, I’ve got the new blocks on the way and have the mast ready to accept them. You really saved my cookies as I’m leaving for a week in Catalina on Saturday…

Thanks again

West Marine has the part. I do not know the part # offhand. Its a Harken sheave.
Duplicates what is there. Call them and give them the dimensions and if you are
lucky with who you get on the phone they will find it for you (assuming you
cannot go to one of their stores).

I think I used 3/8" rivets previously, but could have been 1/2" - its been
awhile
(bolted top sheeve in this time around, since I could reach the bolts).
