Hello, To trim flush the balance bushings, I find it easier to use a good wood chisel. I take care of not waiting too much so the glue is not totally hardened. Leaves a neat surface, eventually a little wood can be trimmed at the same time (shave). I trim with a sliding motion. I've seen others using wooden cauls and trimming on the wood. I too would be concerned by the wear of the cauls if trimming on them. Of course a very good sharpening stone and a little habit for sharpening helps. With the chisel, I trim flush the sides of the front bushing of the sharps. It cut better than any cutter, and the flat side is of good help. I recently bought a carver's knife with the bevel one side, and it seems to be the good tool for that too.
