Oops.
If you weren't wide awake before, you certainly were while that was going down.

That must've been exciting for a moment or two! Did you find some bits stuck in the walls?
Dude. You should play the Mega Millions... 
Wow I'm 1000% happy you are in one piece. Holy smokies man. Be careful!!
Is the underside of the deck good 'n clean now?
Also.
That's not the way you turn drill bits into end-mills.

Most important tech tip for running a mower on a bench, TAKE THE BLADE OFF. Wow.
I also lost a finger doing a stupid thing with my mower while on a bench.
It had the wrong blade on it anyway.
Lucky I didn't catch any shrapnel. I did, in my younger days, mow a little piece of two by four on the bench. A 'shard' hit me in the leg and left a big purple and black bruise that lasted a couple weeks. Just a little 'visual/literal' reminder of what not to do. Like cleaning the carb and plug, and doing several 'housekeeping' items on a mower before checking for compression or to see if it's locked up.
I never run a mower unless it is on the ground, preferably out in the driveway.
Me too, but I've seen a lot of homeowners running their mowers on the driveway and on the street where their houses are facing and use the mower as a vacuum to round dry leaves from the ground through the mower bag
It often will not start like that. Mowers that don't have a blade clutch depend on the inertia of the blade to stay running. For such mower applications, engine designers have created a lower cost lightweight flywheel which is not heavy enough by itself, because it doesn't need to be.
Always test on the floor or ground.
