Product Information:

Rob Cosman has been woodworking for most of his life. While earning a B.Sc. in Industrial Technology/Furniture Design at Brigham Young University, he was Dr. Dale L. Nish's teaching assistant. Rob has also worked with many of the world's best craftsmen – including Alan Peters, Sam Maloof, Tage Frid, Monroe Robinson and Peter Korn. Rob's dovetail marker allows you to lay out both the angled face and the squared end cuts of dovetails so you save time and reduce the chance for errors. Made from eastern maple, Rob planes the angles on a shooting board to ensure the gauge is highly accurate. One side has a 1:6 ratio for layouts on softwoods, the other side has a 1:7 ratio for hardwoods. The top of the gauge is wide enough to mark 13/16" material.

    Comments about Rob Cosman's Dovetail Marker :

    Useful whether you are new to dovetailing or are a prolific pro. Two advantages over the standard adjustable bevel gauge. First, the angle is accurate and consistent, not subject to accidental bump or creep. Second, and more important to me, it acts as a saddle square guaranteeing the angled face mark is aligned with the 90 degree edge mark. I was concerned that it's made of wood (there are excellent aluminum ones out there) but now that I use it I'm pretty confident the only way I'd break it is to step on it (grimace). If you only use one angle, consider an aluminum one. But this T saddle is a clever design that gets you two different angles while still letting you flip it for the left and right marks.
