118° And 135° Drill Point Grinding Gauge
A flat gauge for checking twist drills while you sharpen them. Lay the shank against the fence and slide it into the V: the right face is set at 59° for a 118° point and the left face at 67.5° for a 135° point. Each face has tick marks every 5 mm for comparing lip lengths. The body is 112 x 50 x 12 mm and takes drills up to about 13 mm, and there is a 5 mm hole for hanging it on a pegboard.
Mower Blade Balancer Cone Stand
A bench-top cone balancer for checking a sharpened lawn mower blade: the blade drops over the 53 mm tall tapered cone and the heavy end tips down. The continuous taper runs from 42 mm down to 9 mm diameter so it self-centres any common blade centre hole from 1/2 in (12.7 mm) through 1 in (25.4 mm), and the three-arm foot (88 mm across, 5 mm thick) bolts to the bench with M5 or #10 screws through 5.5 mm holes. Cone is hollow-shelled with an 8 mm vent hole in the centre so it can also drop over a protruding stud.
Flagged: a sharp edge or blade. Not for safety-critical use without independent engineering review.
