Would you believe Ballard has a cheap effective blade sharpening system? If any of you guys have one, lets here your opinions and how well it did on your blades.

just saw this myself and would love to hear a little user feedback on it from anyone! Might just have to bite the bullet and be the first to blow 70 bucks!

$70 for a piece of sheet metal and a adjustable guide is hardly what I would call cheap. You still need to buy a grinder anyway. Save your $70 and put it towards a blade grinder.

$70 for this fabricated bracket and $110 for a 2 hp bench grinder. Thats a $180 blade sharpener. Compared to the $300 one at www.northerntool.com

In my thread "true cost to own my LCO" It was stated that I should sharpen my own blades to save money... Well here I can do it for cheap and It has to be a better job than a angle grinder. Were only talken 10-20 blades a week so i don't know If I can really justify an expensive one.

I've been using my bench grinder without a guide ever since I started and it works fine for me.

Just hold it on a angle, Is there some kind of guide? Blades razer sharp? How well does it stack up to a angle grinder.

Also, would you say the Lower the RPM of the bench grinder the better? I saw a 2hp bench grinder running at like 1750 (?) rpm I believe. A 1/2 hp bench grinder was running 3500 (?) rpm and up. Thats a big difference.

Bigger motors don't need to turn as many rpms cause you run larger cutting wheels.

Yea, but does this translate to a lower temp on the blades surface because of less friction (which makes the blade stronger and more resistent to dull?). With a dad in tool and die I should know this stuff but he's sleeping, guess I'll ask you people.

Well, I used to sharpen my blades with a right angle die grinder. Took forever.
Tried a bench grinder with a mount similar to the one shown. Yep, that's right.
For a bit, it was okay - definately better than a die grinder.
Finally bought a used Foley United 400 and have used it for four years now.
Paid $100 for it and got two wheels in the purchase - one lasts me about six months now.
A particular concern with off-shore made grinders is the actual torque the motors have. It is very easy to "stall" a grinding wheel on the leading edge of a rotary blade causing a cup or dish to be cut into the blade because the motor lacks the torque for uniform grinding.
I am up-grading to a Mag-Na-Matic grinder and Balancer soon.
With thirty blades to sharpen and balance 2X weekly, everything else takes too much time.

It's 2 pieces of flat steel with a single bend. Find your friendly neighborhood welder guy and have him make you one for $25.

$70.. Sheesh.

I just hold it on angle and my goal is not for a razor thin blade just a good cutting edge at a steep angle. If you have a razer thin blade thats real sharp that would be good for shaving but not much good for mowing since the blade would chip for sure. It takes practice but I have been doing it this way for 17yrs so getting pretty good at it. I also like the low rpm of the bench grinder its more forgiving when your first learning.

I lock my blades in a vise and use an air grinder, use to use a bench grinder, but was going through grinding wheels to quickly. If you have a steady hand and good eye there is no need to waste money on a blede guide.
