Re: Friend lost winch
He put it back together and sailed it with THREE broken screws??? Exploding winches can become lethal flying objects, I don't know if I'd get back on the boat until all the winches were completely removed and inspected. It sucks that he lost those parts, but I'm glad nobody was injured.
To me it's like brakes on a car, you do both sides at once because they tend to wear at about the same pace. One side may be in better shape, but if so, that's an indicator of a problem needing addressed somewhere. Those winches were likely installed at the same time, by the same person, with the same hardware. If one had THREE broken screws, the others likely aren't far behind.
Spares can be available, but with Barlow out of business, and some of those spares apparently needing to be machined as needed, it may be cheaper to find a complete used replacement.
