While this topic has been beat to death, pun intended, I'll offer a few thoughts from my 65k miles of spinners and pin drive wheels.
Lead hammers work. I tried the dead blow, sorry no cigar. Lead hammer all the way.
I quit running safety wire after the first few years of my time with SPF spinners, 2004-2014. Did secure the spinners and then hit all again after a few mile test ride. Never an issue but did see a wheel come off another owner's car at Carolina Motorsports Park.
When removing or reinstalling, the wheel should be on the ground, maybe not holding the full weight of the car but at least providing some support to the impact. If the wheel is off the ground the suspension is absorbing the hammer blows and the hammer won't be as effective.
I am not a fan of a turning tool for tightening the spinners. I believe that you need the impact of the hammer. If it works for removal that is good.
And a note for the "low maintenance" owners. You really need to pull the spinners once a year or more and reapply new anti-seize. This will help to ease the removal. Saw or heard about many owners that were proud of the longevity of their tires only to struggle with spinner removal.
Anti-seize is nasty stuff and gets to places you don't want it. And now a cheap plug for a friend. Cobra Valley's Spinner-Eaze works, it's clear and way less messy than traditional silver anti-seize. A small bottle lasts almost forever.

Your car, do as you please, but I get to do the same.
