Hi Roger, Interesting you should bring this up... You wrote: > Walloping the felt punching with a hammer on a hard surface, is preferable > to removing material. I've seen another tech doing this on occasion. I was never taught to do this, and had already been swapping punchings for a year or two before I saw it, so it's not a habit I picked up. What I wondered about was... do those punchings that get 'walloping' maintain their smaller dimension pretty faithfully, or do they tend to return to where they were before the walloping? I can't remember ever seeing or hearing the question or the answer. Any thoughts? Brian Trout Quarryville, PA btrout@desupernet.net
