Continuing on this sheave thread from November, I found this company in Port Townsend that makes black delrin sheaves with bronze bushings. Had me a quote back in 3 hours for replacement 1 1/4' x 3/8" sheaves. Has anyone dealt with him? I will be able to use 5/16" line which is the current diameter on my rope/wire halyards. 3/8" will chafe against the side of the mast head casting. http://zephyrwerks.com/ Thanks for everyone's earlier input.

I replaced the wire/rope halyards on my early (Jerry Montgomery built M17) with 3/8 inch Vectra using the origonal aluminum sheaves and it works great. I have all lines run through turning blocks and led to cam cleats on the aft edge of the housetop. I also have a winch there to tighten the jib halyard. With the very hard fiber, small diameter line, sailing gloves are nice.

Bill: Samson makes a rope called Amsteel™ that is stronger than steel and in small enough diameters to directly replace you wire halyard. It takes special knotting or splicing to hold, but is worth looking into. ⎈--Gary ☺

The wire section on my jib halyard is not long enough to reach to the deck at the stem fitting. When the jib is hauled down the top 2 hanks are still up on the forestay. The rope to wire splice is stopped at the masthead. I can get a new longer wire spliced on, or I was thinking about converting to all rope. However in looking at the masthead casting, there is not enough room for wider sheaves to handle rope. The casting only has a 3/4" slot where the sheaves are mounted. Has anyone done this conversion to rope? If so did you have to change the mast head to another casting? Where does Bob get the masts and fittings from? Dwyer or other? Thanks
