one of my bats is JUST slightly "illegal" - when going through the bat gauge, the spine makes the bat get stuck in the gauge. I think the difference is about 1-2mm in spine height, with the "extra height" running for about 8mm along the spine.
so to make it pass through the gauge, i would need to lower the spine height by 1-2mm (probably just 1mm) in a small section (8mm long) of the spine. can this be be done by just gently hand-sanding that area? I figured by going slow and gently, with fine sandpaper, i should be able to maintain most (obviously not all) of the "sharpness" of the spine?
