As I was about to install a toilet on a recent plumbing job, I made a discovery. I needed to draw a circular cutline on the subfloor for the toilet flange, but I didn’t have a compass handy. I did have my Sawzall, though. I removed its blade, and drove a nail through the hole in the blade into my center mark on the floor. With my pencil resting between two of the blade’s teeth, as shown, I was able to draw a perfect circle — just the size I needed.
