Step 6: Salvaging the 4' 2x4's
I smashed off the wood with the hammer, then yanked the nails.'
Every 2x4 had at least one nail with a stripped off head. I cut them off with an old pair of linesman's pliers.
People have suggested to me that using a sawzall to simply cut the nails was a better way. I _did_ try it, but I decided on this method as being the best. Your mileage may vary, depending on exactly what kind of pallets you want to use.
