C O M S I G N A G E & P R I N T I N G S H O P T A L K We made this two-hole punch for real estate and oilfield sign blanks several years ago. A matching pair of sheet metal punchers were modified with base plates and at- tached to a small, special worktable. The shape of the guide, with multiple rectangular cutouts, allows extra surface area for the tape to hold the guide better, no reason to clamp or screw it in place. Our sheet metal punching tools are off-the-shelf inexpensive models before customizing.
