Query: Another Option to Sharpen a Reel Mower

The sharpening compound works well. I did not want to use the crank or put the gears on backwards (a good suggestion by another individual, but takes a few minutes). I saw another suggestion to use a deep socket wrench on a drill, but did not have a deep socket the right size. Then I tried my 1/2" Dewalt drill and the keyless chuck opened just wide enough to take the spindle. I ran it backwards to crank the reel for 5 minutes with the sharpening compound on the blades and it worked like a charm.
