Saw tooth guide 15 ppi

This is a 15 ppi saw tooth guide to set the tooth angle and spacing. I used it to file new teeth for ripcutting in a tenon saw. You could probably add a fleam angle later, but I don't really know how crosscut teeth are cut. The tooth angle is 80 degrees from the plate to give a cleaner and easier cut than a straight tooth.
The guide is 5" (12.7 cm) in length, but has two holes for pins to increase that length.
