I need an air nailer to put together armadillo traps. They are primarily 1 x 6 pressure treated, some 2 x 2 pressure treated in there. I had a Harbor Freight nail gun that was a 6 in one nailer. It would do several angles and sizes, clipped or unclipped. I had some 2 1/2 nails that worked fine for this use, but it is shot. I bought another framing nailer, but it will only do 21 degree full head 3 1/2 inch I have used my trim nailer that uses the little wires with no head, not really impressed with those for this use. what size nails do I need, and I will find the correct nailer for them. Looked at Harbor Freight today and they have mostly finishing nailers and staplers.
