The inspiration for this thread came from over at decks and fencing when talking about Drills and augers and how I'd recognized people use their cordless drills for heavy duty drilling instead of using a real drill. Here are a few other things I see disappearing in the age of what I like to call the "Home Depot cordless screw gun contractor"
#1 Hand drive nails....just simply outdated or are they? Is it no one knows how to drive them by hand? I've seen deck framers actually frame their decks w/screws.
#2 Framing squares and the ability to read "the numbers on them".....With the proliferation of trusses you might have to do a little overframing in hips and valleys....ah just tape em for the measurement....soffitt will cover any mistakes
#3 Plumb Bobs, water levels......lazers changed this. For long distances I still maintain water level is the most accurate
#4 Combination square...replaced by speed square...at least this one doesn't poke you in the leg all day long
#5 Lumber grading that makes sense....Don't stamp it #1 if it has knots as big as my knee
#6 Carpenters that are true Carpenters and not just one trick ponies
I could go on, so much has changed, I just don't want to completely change with it. If it sounds like a lament it's because it is. Feel free to add more. I already know a lot of the old timers on here, so I expect to hear from them
