I recently bought a 100 lb. Fisher anvil from 1883. When I bought it, it looked liked it had been badly mistreated. I searched forums and took the most common advice on how to fix the anvil, and now have 3/4 inch long cracks transverse to the weld, a lot of it pre existing in the hardy etc. I noticed them buffing the face with a 80 grit sandpaper, and then did a penetrant test on it. What should I do? Should I just leave it alone, or are these cracks going to keep getting longer? TIA
