The sliding blades of this tool and diemakers' square can be adjusted at an angle (up to approximately 10º) with the beam for measuring the
clearance in dies (see sectional view). The larger knurled thumb screw locks the blades at any position, and the smaller one tilts the blades at an
angle. To set the blades at an angle, first release the blade clamp screw, then the blade may be tilted to the desired angle by turning the small
knurled screw into the beam. The blade can be held in position by tightening the clamping screw. Head and blades are hardened and ground.
The inch reading blade is graduated on one side, upper edge in 32nds, lower edge in 64ths and the millimeter reading blade is graduated in
millimeters and 1/2 millimeters.
The bevel blade is approximately 2-1/2" (63mm) long x 1/2" (12.5mm) wide and is beveled to 30º on one end and 45º on the other.
The narrow graduated blade has 32nds graduation on one side, and 64ths on the other. It is 5/32" (4mm) wide over a length of approximately
1-5/8" (41mm) and cut away at one end to a width of 3/32" (2.4mm). SquareS
The offset blade is used where it would be impossible to sight a straight blade. It protrudes from the square about 1-1/2" (38mm) and is 1/8"
(3mm) wide. Both sides of each edge are beveled to provide good visual line contact.
