Marking hacks every DIYer should know
It’s notoriously difficult to mark cuts on curved surfaces. Dropping a straight edge or a measuring tape on a length of tubing or PVC will give you a line to mark against, but it’s very simple to roll or shift your edge when trying to pull a mark. Instead, try this hack: use a length of angle iron to create multiple touch points on the cylinder, stabilising the line and making it easy to draw a mark with a pencil or marker. If you need to pull a measurement on the surface, just put a tape measure or ruler on the flat surface of the angle iron. It’s a great way to make a tricky job simple!
