Marking Gauge

To mark a uniform width slot for the inlay strips, I made a simple but effective marking gauge.  It's made from a scrap of cedar with a pencil hole and a small fence to ride along the one finished edge of the inlay slot.   The small fence is made from a glazier's point, driven in at the required distance from the pencil hole. It simple to make and easier to use than a compass.  It worked well for me because I left a gap as I was installing the strips which allowed the fence to slide easily.
