I've been working on a 70's model BB Mason & Hamlin for a school, nearly finished when I start trying to adjust the spring tension of the repetition lever. Everyone is stiff, nearly half are so stiff as to be unadjustable, to the point of stripping out the head of the screw. I've tried multiple flathead screw sizes and nothing seems to work. Is there a lubricant anyone would recommend? Other suggestions? Bruce Pennington -------------- next part -------------- An HTML attachment was scrubbed...
