Re: Stus-List Masthead sheaves replacement
I replaced my main halyard sheave around 5 years ago with UV Stabilized Black UHMW Poly. I had several made up, thinking I would also do my jib sheaves soon. Well, they were bigger! If anyone is interested I would like to sell them, probably 5 bucks each. They are bored to accept a pair of commonly available SS roller bearings (not included). With these, the dimensions are 5/8 thick, 4 Diameter, and 1/2 axle. Very smooth, as you would expect. http://www.vxb.com/page/bearings/PROD/Kit21063 Bill Coleman CC 39 -Original Message- From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Barbara Hickson Fellers via CnC-List Sent: Wednesday, December 03, 2014 1:08 PM To: cnc-list@cnc-list.com Subject: Stus-List Masthead sheaves replacement The main on Flight Risk is very difficult to raise or more difficult than I think it should be.

Re: Stus-List Masthead sheaves replacement
David, I replaced several of my sheaves many years ago. The groove for the wire is not that deep. All rope halyards run over them pretty easily without any additional drag. I replaced mine because the plain bearing material had worn away. The original stainless steel shafts were easy to clean up with emery paper.

Re: Stus-List Masthead sheaves replacement
When I switched from wire/rope halyards to all rope I removed the sheaves and machined them from a V groove to a U groove. At the same time I replaced the bearings with new oilite bronze. After two years I pulled the sheaves again and the bearings were noticeably worn with cracks at the edges. Replaced them again. Two years later it was the same story so I replaced them with Isomat Acetyl sheaves that run on a matching Acetyl bearing. The bearing was drilled out to be a press fit over the SS shaft. The last part was adding custom cut sheets of delrin on both sides of the sheaves and in between to act as thrust bearings. I suspect that a process was occurring that added significant friction and wear with the previous aluminum sheaves and oilite bearings. The bearings were crushing down enough even over one racing season to allow some slop, which translates into the sheave twisting in the mast head. The side of the sheave would then rub on some part and cause friction as the halyard tensioned. The original setup used two sheets of aluminum to separate the sheaves, both were heavily scored. At some point a previous owner swapped the plates around to get a clean surface again. There is not that many rotations of the sheave under load so judging by the depth of the gouges on the material I would say the twisting force would have to be pretty high. The bearing diameter on the acetyl sheaves is larger, and the plastic to plastic slipperiness presents lower friction than the oilite on SS did. I have not pulled the mast apart to do a thorough examination but a check when I unstepped the mast for the season looked like there was no wear. I did head sail changes during the Lake Ontario 300 in 20 to 30+ kts true. Usually an outside hoist would require hard winching most of the way up, with the new setup it was much easier. The sheaves on a 30-1 are 3.5 OD and 0.5 width, 7/16 ID on the bearing. A reasonable fit was the Isomat 85mm x 15mm ( 3 3/8 x 5/8 ) using a 22mm ( 7/8 ) ID and a matching acetyl bearing. http://www.rig-rite.com/Spars/Isomat_Spars/isomat_sheaves.html The acetyl is rated for handling wire halyards.

Re: Stus-List Masthead sheaves replacement
Burt, I beilieve I need to replace* a jib masthead halyard sheave on my 33-1 since one halyard raises the 135 easily by hand while the other halyard requires a hard grinding via a winch to reach full hoist. My boat is on the hard with the mast stepped. So if you are visiting your boat, I would like to see photos of the jib sheaves and if possible the dimensions of the sheaves (diameter, width, and pin diameter). Knowing the sheave size would enable me to have a replacement(s) ready if and when I drop or climb the mast. * The problem sheave is the one I've used for the furler for many years and the bronze/brass bushing is probably worn and no longer round. Rod Randow CC 33-1 _ bstratton wrote I have a '74 33 3/4tonner. I believe our rigs are very similar if not identical. I just had my mast un-stepped in order to haul the boat to my property for some winter projects. The mast is stored at my marina. If you like I can take some close up pics for you. I should be heading down to the yard this weekend. I have no experience in replacing the masthead sheaves but you might be able to get a good idea of what is involved if you decide to go that route. My main can be difficult to raise also but I chalked that up to my lack of experience and extra hands. I found that feeding it into the track is a huge help but again, extra hands would be helpful. I also learned the hard way to move my running backs out of the way.
