I started cutting the sides for the jewelry box project in shop last week. I cut the front and back pieces properly, but I screwed up the side pieces.

My technique was perfect. My use of the machine was perfect. My measurements were perfect, to the point of anal retentality. I cut a perfectly-sized 3¾” piece.

I was supposed to cut a 7¾” piece.

It doesn’t matter how many times you measure if you’re measuring for the wrong target.
