Drill-Sharp Belt Sharpener

thingiverse

A drill mounted belt sharpening tool. Uses 1/2 by 12 inch belts available from another brand of sharpener. SCAD file can me modified to use cheap air sander belts too, but I haven't done that. This will put convex edges on your knives. When compiling the angle-guides from the scad file, the two inputs are bevel angle and convexity. To make a convex edge, simply pick angles, and then push the knife into the coarse belt until it hits the stop. The belt will curve around the edge setting a convex bevel. Touch up as needed with finer belts. I like to finish with a very fine belt and an angle guide with no convexity. Print Settings Printer Brand: RepRap Printer: i3 Rafts: No Supports: Yes Resolution: .3mm Infill: 70% Post-Printing Build Clean up supports and brims before building. You will need additional hardware as well. Basically you need some 5/16 screws and bolts, 5/16 all thread, a reversible drill, a couple half inch wrenches, and 6 skateboard bearings. I have attached a build video. How I Designed This Openscad is awesome. Use that for everything and modifying your work will be easier later.
