I'm with @Rich Murphy on this one. You don't NEED to have both, but the impact is definitely better for driving screws. I have some quick change drill bits too. That way I can drill pilot holes and install screws with out the need to cart both tools up the ladder.
My current passion is making projects with pallet wood. Pallets are free and made of assorted hardwoods. It takes a little more sanding and finishing but the grains are great. Here are a 8' x 5' bar and bar stools I made for a friend.
Which is best, Titebond or Gorilla Glue? What's your favorite? I'm doing some testing, trying to see for myself just what the differences between them are.
I haven't really done woodworking since high school, and I graduated in 1987. My father and I are spending some quality time together over some woodworking, and so far it has been fun.
