Those using a handheld grinder for blades

For those who use a handheld grinder for blades.What type of wheel do you use. I used a friends who a special type of wheel for i think for aluminum that took to the blade real good without using much pressure.

most wheels for grinding aluminum are made with sillicon carbide. Since aluminum is a soft metal it clogs harsher grit wheels in a flash. For my blades and most all my metal grinding i use zirconium flapwheels by norton.

I'm going to use an angle grinder on my blades this year. The suggestion I read was to use a carborundum-coated/fabric backed disc on the grinder. Supposed to do the job quickly and easily.

I used a dremel too for a while to grind my blades. I now have a cheapy bench grinder from costco that does the job very quick.

it's only about $45.00 from costco to get a bench grinder and if all your doing is grinding blades it should serve you well for a while. it really cuts down on the sharpening time if you have multipule blades.
If you are believing the Truth, it will never let you down.

A student taking a philosophy class had a single question on his final: "What is courage?" The student wrote: "This", signed it, and turned it in.

in Iraq, ever since the beginning of time, men have fought for, land, power, money, and greed. but what are we fighting for? .... we are fighting for something new, we are fighting, because it is the right thing to do.

Don't round off the tip of the blade with a grinder. If the square shape of the ends of the blades get rounded off , you will start to see uncut strips of grass, because the blade circles won't quit overlap anymore.

I use a 4.5" angle grinder too. the layered sanding discs work great for me. make a nice clean edge. iv'e tried a bench grinder and hated it, and yeah it's easy to start rounding the end with one. Iv'e even tried a Lesco blade grinder and I don't know if they are just junk or what but no matter what I did to adjust it it sharpened terrible. So i stick with what works, the 4.5" angle grinder with the layered disc.

The fastest way is with a 4" angle grinder with a 50 grit sanding wheel backed up with a cut off wheel. I use the cut off wheel as a backing because the standard rubber wheel they provide can get chewed up if you slip off the edge. I have done thousands of blades....and balancing don't seem to be necessary. I have never had to replace a bearing in spindle ...25 years and many mowers.
