At the same time, Lochhead expanded his knowledge of printing techniques with hand presses that used metal and wood type. He and his students also experimented with paper making. "I remember Rob Davies saying, 'I was going by the printing room, and I heard your students laughing. It's the first time I ever heard laughter coming out of the class on bibliography,'" Lochhead said later. "Well, we did laugh—we'd get ink all over ourselves, we'd make mistakes, and I also had anecdotes to tell, the things you pick up in teaching, you know."
