I recently picked up an old junker 26" rip saw to practice on. I needed to joint the teeth approximately 50% because it was a quite uneven. Then I went ahead and re-shaped the teeth. Now I measured the set. It varies from 20% to almost 50%. I use dry hardwood so I'd like to get them all to 20% (that's what I have read but I am open to suggestions). Do I use a ball pein hammer and lightly tap on an anvil?
