Without doing the math on an 11,000 rpm machine driving what appears to be a bicycle chain, my guess is this might not be the best thing to do with an angle grinder.

Chain sprockets look pretty close to 52 teeth and 13. So 3000 RPM at the blade, give or take.

Too much time spend shooting needless video with not enough time spent on good design. If he wants to spin that chain the hard, a guard might be a good addition.

The use of a much larger driven sprocket is a very good point. I was thinking about the small chain size combined with the drive speed resulting in metal shrapnel flying everywhere

In order for this to be really useful, wouldn't it need to be made on a much larger scale? Or is this for the cattle rancher with only a dozen or so cattle?
