Matthew, I have four of the large Merriman snatch blocks on my boat. Over the years, all the center shafts have failed at some point. The little screw that hold the holds the shaft in simply isn't up to the task. If you want to fix it for less than 5 bucks, get a 3/8" x 3 1/2" stainless bolt, which has 2 1/2' of solid unthreaded shank for the roller to use as a bearing surface, and cut off just enough of the threads with a hacksaw to accept a washer and locknut. If I recall, you have to drill out one of the cheek straps to 3/8", but the other strap already has that size hole. Its not as pretty as a the original, but it's not coming loose, and I'm guessing the snap shackle will fail long before the shaft and cheeks.
