Based on earlier answers here and other places, I have decided to use my pneumatic die grinder to sharpen the flails on our 5" mower in place. I will disconnect the mower and roll it over so the flail drum can be accessed. I haven"t decided exactly how to hold everything in an accessible, solid position, but I"m a pretty good equipment operator so will figure out something.
My question at this point: What is the best kind and source of die grinder stones for this operation? My die grinder has both 1/8" & 1/4" collets, but I"m certain the 1/4" shank stones are best for this relatively heavy duty operation. I don"t know what grit to ask for, nor where to get the best deal on stones that will work well.
Thanks in advance for the help!
