Would you reuse these rotors?

Me, in my younger days, I would take an angle grinder with a sanding pad, with the rotor on the car sand away. If you was good with holding the grinder/sander, it will spin the rotor while your working. It was just enough to get the glaze off and the rusty edges. And I have also brought the rotors in to have them turn, only to be told it would be to thin to have them cleaned up. I told the guy to clean up the one side with the grooves, it passed the thickness test.
And to make sure, I am not telling any one to do such things, not recommend by NO means. But this is what I had to work with. It got me by......Now days, measure by the book, no pass, buy new....
