Just got it set up and sharpened my 24” buzz saw blade. As heavy as the base is ( made out of cast iron) this blade, when mounted would almost tip the sharpener over. Won’t be a problem with smaller saw blades. I had to make a center adapter for this blade had a larger hole than the ones supplied with the unit (not a problem for my shop). It comes with a diamond wheel. Some indicate that they don’t get but one or two blades sharpened before it wares out, but in their pictures they are not using the water cooling. Take the grinding slow and use the water cooler and it should last thru several blade sharpening. The diamonds don’t ware out, they get knocked out of the binding material. The angle markings seem to be spot on, this makes the set up quick (once the individual blade settings are figured out ).
