Should I sharpen my blades "knife sharp" or should they have a blunt cutting edge? Which is better? Stick it in a vise and use cheap mill files to make it similar to the way it was new. A grinder would be much easier, but it's not all that bad. daveA -- The only technical exercises for all guitarists worth a lifetime of practice: "Dynamic Guitar Technique". Nothing else is close.

I already have a grinder, and a vise. What I am asking for is the technique. |

I use a 4" angle grinder. It works pretty good for sharpening them. I can't seem to get more than a couple of cuttings before they blades are all beat to hell. I do have a few sticks and things in my yard, but no sandy soil. I don't know why my blades get dull so quickly. |
bench grinders with round wheels is a bit more difficult unless you can
master holding the blade at the precise angle everytime... I dont have a bench grinder so I use a sharpening stone specifically made for sharpening lawnmower blades that fit into drill motors/ cordless drills. Also I have an attachment for Dremel tools that are specifially made for sharpening lawnmower blades. The Dremel attachment isn't quite as good since it is hard to menuver the attachment around the part of the lawnmower blade which is bent up for air deflection. I nice new flat file would be the better way to go if you have the time. James wrote: While we are on the subject, can someone try to describe the entire process for sharpening a mower blade? When I get a new blade, I know what it looks like, but I don't know the correct "approach" to get it sharp. I use a small bench grinder, and I hold the blade up to the grinder, but usually I feel that I am grinding off more blade than I need. It seems that knowing the correct "angle" to hold the blade to the stone is the key, but for the life of me I can't seem to get the hang of it. And no, this is not a troll. --James-- |
take a new lawnmower blade... it is usually painted black. Take your
grinder or file and grind the edge so that the paint is filed off evenly. The new shiney edge should be even and straight exactly at the same angle of the blade edge. So on an old used lawnmower blade you will make the new shiney edge even and straight. James wrote: I already have a grinder, and a vise. What I am asking for is the technique. |
