So I am trying to make my new goat shelters using the materials listed as 'free' on Craigslist. I have a stead supply of pallets locally. I think I can re-use this junk wood rather effectively in making new goat shelters... however, what tips might one have for taking the pallets apart? I am using the claw of a hammer and a small sledge to start prying the pieces apart then using nippers to remove the nails. The wood is quite thin in most cases and if not reasonably careful I can split it while trying to pry nails loose from the psuedo 2x4's used as the frames. Any tricks or tips for de-construction out there?
