Tips for blade sharpening, how do ya’ll do it?

For sharpening a mower blade, I have started using flap grinding wheels, and there's nothing that removes as much material as fast as a flap wheel.

A (bench) belt sander is easy to use leaving a smooth finish compared to other methods used. The rounded end on the sander can also be used for curved blades. Buy a dedicated balancer if you are serious about blade balance. You don’t see a tyre (tire) fitter not balancing a new tyre on a car, which doesn’t spin as fast as a mower blade. I guess that the heavier and longer the blade, the higher the necessity for correct blade balance.

I’ve seen ads for blade sharpening tools and such, I used to use a bench grinder to sharpen them until I got an angle grinder. I’ve been using that, but I feel like there is a better way to get a flat edge with a consistent angle. Any opinion on drill mounted sharpeners? Perhaps ya’ll have or use something else? Any way to speed this up?

After research on blade sharpeners, I saw one American model that cost $269.00. I found a sim looking model on temu for $56.00 and ordered it. I had to do a few little mods at the joints for smooth action. I use a flapper disk 36 grit and get amazing results. Adjustable angles for different blades, (I use 30 degrees on most blades). I'm away from the shop now but will post info from the container when I get a chance. Good luck with the cheaper model.

I'll be getting a flap grinder for my Makita .

Sorry Stevestd - no idea how Took MakerTims name got attached to your words

You only have to worry about blade balance, when you damage the blade OR sharpen it.
Can only try and avoid damage - S--t happens!
Sharpening is a deliberate choice, that you impose on yourself, for little gain & substantial cost.
