re: TIPS ... for precision cutting

I don’t know about anyone else but I measure twice knife once mark once and cut twice. Let me explain. First I take off the glasses and close the weaker eye then measure and write it down. Then walk around the bench or project to make sure I’m not missing something. Then measure again and compare to my noted first measure. Next I cut the mark into the wood with my marking knife, closing the weak eye again, making sure to go all he way around, even if it’s just a table saw cut. Then I mark in the cut groove with my pencil. And add an “X” to show the waste. Lastly I cut twice, my first cut is about two saw blade thickness away, just to eliminate blade flex. Keeping tool blades sharp and clean in critical to a smooth cut. Most people don’t spend the time the way I do but I rarely waste by making a wrong cut.
