I'm now working on the lifts. Where the lift comes down through the top it rubs against the edge of the lubber hole. (see the blue arrow and temp green rope in the pic) This doesn't seem right as it would fray the rope eventually. None of the books I have mention this, but Mondfeld does show the same thing on pg 314. I've measured everything twice and all the parts seem to be the right size but there is no way I can get the lift to go in a straight line without cutting away most of the top. Can I trust Mondfeld on this one?
