Now to clean up the baselines. I do this using a bench hook. Before chiseling, I deepen the scribe lines on just the waste using a knife. Pro tip - A sturdy bench helps a lot with chiseling. If you don't have one, position your work right over a leg. This will eliminate any bouncing or spring and transfer all your energy where you want it. Also I prefer a heavy metal hammer to strike chisels. The less force I have to put into my swing the more accurate I can be.
