I use a stationary grinder with a 1"x42" belt. I have tried all kinds of belts, and can tell you that the best belt is a Blue Zirconia belt made of aluminum oxide and zirconium oxide, 40 grit. This belt literally tears the steel away in a hurry without giving ittime to heat up. I don't bother to smooth the edge of the blade --- at the speed of the blade, the difference between a perfectly-smooth edge and a slightly-toothed edge is insignificant. Saves a lot of time for the process. Of course, removing the bur on the edge is important.

A 60 grit sanding belt will sharpen blades much faster than a grinding wheel and doesn't generate as much heat doing it as only light pressure is necesary. Balance the blades while sharpening and bearings last longer. A steady rest will help maintain the proper angle and reduce the tendency to rock the blade from the drag on it when I have the time. I use a 7" hand grinder with 60 grit sanding discs to sharpen the brush cutter blades without removing them when time is running out and the 1001 other things needing done are pressuring me.

I use a belt sander for sharpening many different tools and general grinding of parts for welding and fitting etc. It is one I made using a contact wheel from a Baldor which is the only part I bought. It is a 2x48" belt, the contact wheel is about 6 or 7" in dia. and it runs at about 3400 rpm. You need to watch that the part to be sharpened doesn't over heat, other than that it works fine.

One more thing to think about--If you have a dust bag on the sander TAKE IT OFF BEFORE GRINDING ANY STEEL or you just may have yourself a nice little fire in the dust bag!! I have seen this happen to a guy on one of our jobsites. Guy was lucky tho' he only had to replace the bag, not the sander,... or house.

Beltsander will work for sharpening an edged tool and the proper way is to grind away from the cutting edge. This puts the heat further back the blade instead of at the cutting edge. All looks to be going well until all of a sudden the edge of the blade snags the belt and you eat a lot of belt before you get the word DAMN out. Fred OH

I have not personally used a belt sander for mower blades but I have used a belt sander (machine style) for sharpening axes, and mostly drill bits at work. A couple of guys at work laughed at me when they saw me sharpening drill bits, but when they saw the nice cutting edge and the way I roll the drill bit upward to get the relief on the web of the drill they shut their mouth and said "wow that works good" I would say yes you can sharpen mower blades as long as you have a way to hold the blades stationary while you use your sander. I am assuming that you have a medium sized handheld sander. good luck.

I have used a 2" belt sander to sharpen my rotary cutter and finish mower blades for years and it works great. I like it a lot better than a grinder because it's faster and easier to maintain the correct shape and angles. Make sure you have a sander with decent power and the correct type of belt for steel, I get mine at Sears. If my rotary cutter blades get too bad I rough cut the edge on a mill first and then dress it up with the sander just so it doesn't take so long.

I don't believe it would work since a sander is made for wood working and if it does it would take a very long time to move enough metal to get it sharp but it would make them look like crome
