I have a question . Does any company make a similar adapter for a regular bench grinder ? It seems like it would work nearly the same way. I would think it would do a good job.
China.... :( I just bought my YH directly from the guy who designed them. Very nice man to chat with on the phone. Those knock-offs vary widely with the "this is a 30 degree angle" and such. I'd rather support a small, USA business!!
Follow up Q - do different blades take a different sharpening angle? I mean, this looks pretty solid, is there a way to make adjustments like that or “you get what you get?”
All blades from what I have experienced take the same angle. But this will only work for flat blades. Some mowers have blades that have a dip or hump in the middle of the cutting portion of the blade. Those would have to be sharpened by hand without a jig.
