as construction has shifted over from hand nailing to power nailers, the "hammer snob" position has been that hand nailing structural framing is still superior, because the hammering also pushes the wood more tightly together, resulting in a stronger joint, while drivign the nail with a power nailer doesn't. there is also a debate over whether a person should press the nail gun to the material and then squeeze the trigger, or if it is acceptable to hold the trigger and bounce the nail gun on the material, letting it fire when the bounce depresses the tip safety. the contention is that nail placement is less accurate when bouncing the nail gun. however, I'm a bit curious if the bouncing nail gun comes a little closer to how hand nailing knocks the joint together, resulting in a more secure joint.
the logic is that this is a bit like using a floor nailer, where the flooring is held tight, the gun placed in position, and then fired by smacking a top trigger with a rubber mallet, this forcing the flooring tightly against the subfloor and the neighboring piece.
anyway, obviously something I can test if I ever get around to building my woodshed, but also something that can be discussed in committee.

I haven’t had much experience with power nailer‘s other than the ramset type that uses the explosive charges. And those seem to have no problem securely fastening wood, or anything else for that matter, to concrete. When I rebuilt the pump house up at our cabin, I used screws.

When I rebuilt the pump house up at our cabin, I used screws. it's a running joke with one contractor that they use screws for changes so they can take them apart and change them again. the trim guys all use pin nailers now, and they like them because they don't disturb wherever they are holding the trim - because you don't always want to pull the trim tight. but in framing, there's the question of power nailers drive the fastener into the wood so quickly, that is doesn't have the clamping action that banging the nail in with a hammer does. if the wood is an eighth inch apart before you shoot the fastener, it stays an eighth inch apart. my ramset is a basic hammer actuated model, so similarly, you have the tool hitting the material as the fastener is fired but is that enough impact to take any incidental gap out? |

I think if a carpenter consistently has an eighth inch gap, they need to re-calibrate their tape measure. As for the nail gun, I would think that with the force most of them have, the head of the nail would be enough to pull the pieces of wood together. Isn’t that why nails have heads? |

Isn’t that why nails have heads? nails have heads to make it easier to hit them, and easier to pull them back out. case in point being pin nails, which don't have heads. you can't hand drive them, and you can't pull them back out. and no, it's not about measuring, it's about not clamping. |
