4. Using a Hypertherm Powermax45 plasma-cutting system, we cut the trunk in sections. First we drew the rough cut’s lines, using a piece of angle steel as a straight edge. Using this straight edge to guide the torch helped us keep our hands steady and obtain a clean cut through the metal. On the top right of the photo you can see where the cut was done freehand and we had to go back and recut a few places. We saved all of these pieces in case we needed them for reference later on.
