We use a Neary blade grinder,with a new wheel about every season. Blade balancing comes courtesy of a standard cheap balance, I think the last one was an Oregon. These we replace every cutting season.

[QUOTE=mike174;3439161]Grassman - I doubt he's serious (refer to his eyes rolling face).


Also refer to Magna matic 9000, Blade balancer in signature. Blows me away that someone with 11 years in business still uses a nail.

[QUOTE=ALC-GregH;3439576]I use pretty much the same thing as Richard and it WAY more accurate then a nail.

Is that a little bearing between the two nuts?

I have never tried this "nail" theory. But, why doesn't it work?

i dont know much about the internals of balancers but i would guess that they have ball bearings inside which would make it much easier to spin if the blade was out of balance, and less friction then when using a nail. the more friction the less acurately balanced the blade will be

2 reasons.

1: As blakerugg said, the blade is not free to rotate on the nail. The blade could be grossly out of balance and you'd never see it.

2: This is related to number 1 but if you watch my video you'll see me adjust the position of the blade on the nail. The blade appears to go from slightly out of balance to balanced when it's on the nail. It is extremely difficult to get the blade centered properly on the nail so you can even get an indication that the blade is out of balance. I could have just as easily shown that the blade was out of balance towards the other direction if I had wanted to. That's not possible with a bearing.

My Sharpening Attempt

I have never sharpened my own blades before today. I used an angle grinder with a 60 grit flap disc. The blades are sharper, but not as sharp as I would want them to be. I can run my fingers across the blades with a little pressure, and not even blink. Am I doing something wrong, or is this the way it is with what I have?

I dont sharpen my blades to a razor edge. I used to, but they loose that edge so quick its not worth loosing the extra metal. I sharpen down to something like .5mm rounded (blunt) edge. Sharp enough to cut grass but it seems to keep that edge longer.
