That "measure twice cut once" rule is missing a step
I keep seeing guys on job sites measure twice and then just go for it without thinking about the kerf. You know, the width of the saw blade? I had to redo a whole set of cabinet doors last spring because I measured twice with a tape, but my circular saw ate up an extra 1/8 inch on every single cut. That mistake cost me about $80 in plywood and a full Saturday afternoon. If you're using a table saw or even a handsaw, that tiny line of wood dust is real material that just disappears. I always mark my cut line and then account for which side of the line the blade goes on now. Has anyone else had this bite them on a big project?
