I would admit, Zephyrworks is awesome. I had a full set made for my Cal40 and everything fit perfectly. They were great to work with and extremely quick in delivery.

Not cheap, but they will build any sheave you want and are very top quality: http://zephyrwerks.com/ For halyards; 3/8" Sta-set works OK - relatively low stretch. 3/8" Sta-set X works better -- has even less stretch, but it "grows" after a while and in my case the cabin top clutches now are too tight, making it harder to handle. My Lewmar clutches were expensive and it's painful to think about replacing them. Spinnaker Pole length should equal your "J" measurement from the mast to the headstay. Cal 29 should be 12' 3" and this per PHRF rules if you want to race her as such. I replaced one of the through bolts on my stem fitting with a piece of 3/8" stainless threaded rod, cut to the proper length. I bought a section of 1" stainless tube and a 3/8" threaded stainless eye - http://tinyurl.com/eyenut - to cap it with. I made the tube/nut combination 6" long so it would clear the bow fitting but not carry too much side loading. It looks marginal but has worked like a charm for several years. I believe that the latest PHRF class rules allow this modification, though your local PHRF may not. Hope this helps: David Wilkie Owen On Jan 23, 2010, at 7:45 AM, cayugacalsailer wrote: Cal group, Upgrading from wire/rope halyards to all 3/8 rope. Looking for sources to purchase new sheaves.

Don, make sure to check the thickness. In some cases, the old sheaves were skinnier. Standard spin pole for symmetric chute would match your J measurement (front of mast to forestay base).

Charlie- Very good point. He only gave the diameter, but if enough people are having them made, then It may mean they are not available in the required thickness. R Read S.

Well, once again a lot of helpful links/tips. Thanks Sheave thickness is exactly 1/2 inch. Don't know if the old ones were original, but have them here. They're made of some kinda brownish composite material, doesn't look plastic, definitely not any type of metal or alloy. Think I will give Zephyrwerks a call. Rig-Rite has the exact sizes I need, but availability is iffy. I was thinking 12'3" for the spinnaker pole. Thanks for confirming it. Since haul out in October I've purchased new halyards, sheets for the blooper, had the sails serviced and cleaned @ Sailcare (I highly recommend them), and now working on the new sheaves. Think a spinnaker pole might wait a bit. Really looking forward to playing with the Blooper. How much attention should I pay to the pin in my sheave project? It looks to be 1/2 inch aluminum and in decent shape. Thanks once again Don Trepanier '74 Cal 2-29 Moses #613 Cayuga Lake Husar, Charlie [USA] wrote: > > > Don, make sure to check the thickness.

Don: I haven't been following your thread, just saw this latest post. If you're looking to replace the blocks with the original material, those are likely made of tufnol.

You desceiption of the sheave material matches my sheaves, which are Phenolic. Mine were machined by Svendsen's Marine in Alameda. There are actually 5 things you need to specify. Diameter, thickness, hole diameter, hole lining (bronze or not), and grove shape. There are 3 basic grove shapes. Wire is a "V", rope which is half circle, and high tech, which is a "U". There are also combinations like a half circle with a "V" in the bottom that will hold either rope or wire. My pin is a SS bolt. It used to be bronze but I bent it. There was no sign of wear in the old phenolic sheaves in the hole area after 50 years so I didn't get the bronze insert and am not too worried about the pin. I used SuperLube to grease things up, which was recommended by Svendsen's and is the best grease for a boat owner there is. I replaced mine because one of my crew ran the halyard up hard with the jib tack not snapped. The other thing to note is that this material is not always the same thickness because of how it is made. They can machine it down to size but that puts a rough surface on it instead of the stock smooth surface. Or you can get it a few thousands oversize if it happens to be a little thick like I did thinking it would be fine and spend 4 hours at the top of the mast sanding to make it fit. Obviously, take the time to figure that out and don't do what I did. Allen On Sun, Jan 24, 2010 at 7:59 AM, Donald <dt… [at] twcny.rr.com> wrote: > > > Well, once again a lot of helpful links/tips.

We used bloopers on IOR boats to improve steering balance . It added 1//4 to 1/2 a knot. It is trimmed with the halliard as opposed to the sheet. So the mast man trims it. Let it way out till it almost touches the water in smooth seas .It adds another layer of complication and is cut very full so it is best when going deep. You competition will know when you are going to gybe when the bloop comes down.
