I want one of these
I think that might be possible using some sort of gyroscope stabilization deviceOK... try sharpening a bandsaw blade using a 9" angle grinder with a masonry disc, wearing a no.15 welding shade and boxing gloves, on a foggy day, while bouncing on a Spacehopper, on top of a waterbed, on a trampoline
I didn't say I could do it
The biggest reason people cannot sharpen drills is the most overlooked one. Anybody can sharpen a drill. Nobody can sharpen a drill on a wheel that is shagged. Forget the jigs and the gimmicks. Get yourself a decent wheel dresser and it’s so much easier on a square and unclogged / unglazed wheel....
