FYI, Just installed five boat trailer rollers in the bunkboard that my Monty 17 keel slides on. Now it rolls on and off the trailer with just the port and starboard bunk boards rubbing on the hull. Discovered that the "Pal Nuts" that come with the 5/8 inch diameter axles are an iffy product to use. Had several of them tapped onto the ends of some of the axles. They were all the way on, about 1/2 inch worth of axle inside. Then happened to pull on one to see how well it grabbed the metal axle. It came right back off in my hand. Went on to check all of them and about half were just sitting there just waiting to come off and allow the spinning axle to unscrew itself and dump my beautifully restored keel down onto the metal braces for the rollers. Ouch. Ended up removing all the "Pal(?) Nuts" and drilled all the axles for 1/8 inch ss. cotter pins on washers at each end. This year's "shake down cruise" is fast approaching.
