Finally got round to examining my aft keel roller. The axle is not a bolt like Jim's but appears to be a metal dowel. The hole is (or has become) oval. The roller is jammed solid. Has anyone come across this arrangement? The dowel appears well fixed, there was quite a bit of rusty steel/iron in the oval holes! not, I think, from the keel, suspended in grease.
Has anyone got the measurement for the stainless steel strips that hold the lower block to the keel? The arrangement on mine has been altered. The season gets closer, and like most years I am awash in outstanding jobs! I don't feel I've time to experiment. Any knowledge gratefully received. Jon
