After making a couple of table out of pallets and nailing them together the old fashion way, I decided to buy a framing nailer to speed up the process and save my fingers. I picked up a box of standard 2 3/8" nails when I bought the nailer. After spending what seems like days sanding all the wood down so it can be stained, I finally got to the nailing part today. On the very first board I tried to nail, out of the 6 nails fired, 4 of them split the living hell out of the pallet wood. The nailer is only getting 75psi, which is having no trouble sinking the nails. I did some basic research on how to minimize this (blunting the tips/pilot holes etc), all of which is easier said than done with collated nails. Does anyone have any advice on how to overcome this? My project is at a stand still now because I refuse to destroy anymore wood that I spent so long sanding. I did a brief online search at the local big box stores for blunt tip collated nails that would fit my 21 degree nailer, but came up with nothing... Any help is greatly appreciated!
