Anyway, here's what I've got so far. Right now, it's just round on the top, but I'll be milling a hex into the top of it so I can use a wrench, or a 6-point socket, and never have to worry about rounding it off or using a set of vise grips on it.
I never even considered using the 1/4 drive hole. I just pulled out one of my favorite weapons, the big vise grips, and grabbed the top. No muss no fuss, off she comes.
I like the big vise grips a lot. You can make a mess with them if you are not careful, but you don't have to.
