I was flaming them for offering something way over priced to sharpen mower blades. However, the machine is so versatile that it can be used for so much more that the price starts to look appealing! I'd have one if I could afford it. I do "some" metal fabbing and do it well. I just don't do enough to justify the cost. Great machine if you do a lot of metal fab work and you need to sharpen some mower blades.
I was considering this sander. I think it would work to sharpen mower blades as well as other stuff.
