To the list - I ran into the worst case of jumping pins that I have ever seen today on an old Hardman grand. A4 was only 6 cents flat at start and when pulling to pitch a good dozen would jump up and then when setting the pins, those suckers would drop out of site. What the heck causes this and is there any easy remedy? CA? Sandpaper shims? Repining? Don Bee, Chicago
