Not a lot of regular nails being used any more. Either screws or air nailers. I picked up a framing nailer several years ago when we put up the pallet building and machine shed. Later I drove by a yard sale one day and saw some air hose. Went back ang got to talking to the guy and ended up with 100ft or air hose and around 3K framing nails of various lengths for $60. Took me over 2 hours to sort out the different nails. Those loose ones will drive with a hammer too.Most of the nails will go in the garbage as my hands don't hang on to hammers all that well any more. Good for some whacks but steady hammering like the framing days, can't happen any more. That's why I have to use screws a lot in wooden construction like those tractor decks I built for the lift.
