![]() ![]() Shoot one pin into each end of the assembled joint to preserve critical alignment, then apply clamping pressure. Glue is slippery and clamps only make matters worse unless there’s something to hold the joint in alignment. Whenever you’re gluing pieces of wood together – especially large pieces of wood with lots of surface area – it’s almost certain that parts will slide out of alignment with each other under clamping pressure. After finishing this mark all but disappears. The tiny mark here is a very close-up view of what’s left behind by 23 gauge pin. But even when you can get clamps onto project parts, pins can still help. Small pieces of trim or wooden model parts that are difficult to clamp because of their shape are easy to hold tight with a judiciously applied pin or two. Although the strength of pins alone isn’t huge, they are ideal for holding wooden parts together while glue dries. I use my pin nailer most often as an instant clamp aide. On the surface all you see is a small spot that’s virtually impossible to notice after finishing. Some models are even capable of driving 2-inch long pins into wood as hard as oak or maple. Place the tip of the tool onto the wood surface, pull the trigger, then listen for the small “thunk”. About the same diameter as a sewing needle, these pins are so tiny that they join wood almost invisibly. Pin nailers get their name from the small, headless, 23-gauge fasteners they shoot. Pins are virtually invisible when driven correctly. The sewing pin (top right) shows the relative size. The two dark spots on this red oak board are 23 gauge pins. I made the video above more than 10 years ago, but it’s just as relevant today. These small, quiet, up-and-coming air tools offer an advantage for hobbyists, homeowners, professionals and anyone interested in joining small pieces of wood. They won’t take the place of traditional finishing nailers, but they do offer something that no other air nailer can accomplish. Just last week I met a professional carpenter who had never heard of them. Instant and virtually invisible wood joints – this is what 23-gauge pin nailers deliver. They’re not quite mainstream yet, but they’re getting there.
