Posi-Driver & Hand held impacts are what I always used "back in the day" too! I also have an old crank handle drill that my grandpa used to use! PLEASE! Hand me that cordless drill any day! For me, that is what I now think of my hand held impact driver...It basically has been obsoleted from use. It still is a real nice backup when you are away from compressed air though. When I took my striker plates off last year, rather than bring the air hammer home from work I grabbed the trusty "old hand-held" and gave it a couple firm swings...NOTHING, I tapped several more hits while turning it like you are supposed to and then I stopped. I realized I didn't HAVE to do that the "old way" anymore! Next day, I brought the aforementioned Snap-On attachment and the air hammer home. 10 seconds later, one was off, then both were off. No swinging and super-easy! Like a hot knife through warm butter! To me, it really felt archaic to swing the hammer so hard so much, watching the metal jouncing...IMHO, I swear by that air chisel attachment...once you've use it...you'll pretty much NEVER want to use the "old stand by" if you can possibly help it. It works on so many more things than just these screws. It works on rusty bolts, shaking the rust from the threads while turning. It works on drain plugs and differential fill plugs that are sometimes rusty or damaged from other "Hammer-Techs" Trust me, the old "IF all else fails, GET A BIGGER HAMMER" line is the worst idea EVER!!!! I REALLY mean that! You WILL beat the crap out of your pillar post going that route if these screws are REALLY stuck and/or RUSTY!!!! It truly is worth the investment. (NO, I do not SELL Snap-On tools for a living, I earn a living with them though)
