After trying various things including nothing I have been happy with thick rubber pads. I purchase a couple of feet from a roll and trimmed it.
This may be the product, I think there was a choice of thicknesses at the store: https://www.princessauto.com/en/detail/heavy-duty-checker-plate-rolled-rubber-mat-by-the-foot-/A-p8681660e My thoughts were that the C&C 30-1 mast is stiff and even with a lot of pressure on the backstay it did not bend much with the mast blocked hard in the collar. There was some bend but more just pulling the masthead back inducing rake rather than putting a curve into the mast. When the mast is stepped I can leave the strips out, center and tune everything, then may adjust the heel to center the mast in the collar. The strips are in two pieces and run in a semicircle at the front and back leaving room for the hold down strips. The mat thickness I am using, slightly less than a quarter inch, will slide in from the bottom by forcing the mast back then forward. When checking the mast you may want to take the mast top casting off, held on by eight machine screws. The original sheaves are aluminum with a pressed oilite bronze bearing. If the bearing wears or crushes out the sheaves can lean, wear or jam. I replaced the bearings and found them to have worn significantly in two years. I replaced them with "hard plastic" Acetal sheaves that are wire rated though I have all rope halyards. I drilled the centers out to a larger diameter and made a plain bearing arrangement with another Acetal donut forced over the stainless axel. That has lasted years with no wear and is much easier to hoist with. Michael Brown Windburn C&C 30-1 Date: Wed, 6 Feb 2019 21:58:27 -0500 From: "Steven A. Demore" <sdem...@computer.org> I had my C&C 30 MK1 dismasted yesterday to do some work on it. The boat came with no wedges in the deck collar, so I made some one day, just to get through summer. While taking down the mast yesterday, I asked the rigger what kind of wedges it should have. He said he wasn't sure whether C&Cs came with wedges, or a metal spacer. Does anybody know what the factory used to support the mast through the deck? Also, while I am at it. Any suggestions on anything I should be checking on the mast? I'm replacing the wiring, going to LED lights, replacing all of the running rigging, new blocks and sheaves, and checking out the step. The boom has the internal blocks and wire for tensioning the foot of the main, but I don't know whether that is accessible for maintenance or not. One last thing. I was planning to mount steps (the triangular aluminum ones) on the sides of the mast. The rigger recommended against it because of the number of holes in the mast. Anybody have thought on whether a series of small holes (1/8, 3/16??) would weaken the mast? Thanks, Steve
