Seems to me to be a big deal about nothing, socket can't damage the flywheel, they are both travelling at the same speed, if the socket decides to jump off it just falls on the ground. Trust me I have never had to go looking for a far flung socket, and the only reason my socket might come off is because it is all a bit loose from years of hard work and as it doesn't cause me any more problem than having to bend down (that is the hard part) to pick the socket up off the ground. My setup is a 3/8th socket shaft that I turned down at least 30 years ago so it would fit in my drill chuck, then it has a 3/8th to half inch adapter and then a 1/2 inch drive socket to fit the nut on the top of the crank. I have been doing this sort of stuff for close on 60 years and if I thought it was dangerous I certainly wouldn't be doing it Each to their own, but I will continue to start and test run mine with my half inch electric drill
