As well as the hammer felt close to the core swelling from the water in the formula, and more or less exploding the system of compression of fibers, which is really pretty tenuous: it doesn't want to be stretched around the core to start with, and the fibers are compressed that much more in the interior, and even without added water, they are trying to "burst free." Add water, and they have that much more pressure to apply. I wonder about applying a formula with less water content (91% isopropyl for instance) and not entirely saturating. I have some old Hamiltons ripe for experimentation, as well as at least one set of hammers and butts that I salvaged and saved. When I have time, I'll fool around.
