I've been breaking down pallets for years now. I don't want nails on my boards as I don't want to wreck my blades and equipment. I also want to have boards as long as possible to make sure I have options and to not be limited. This is how I do it. I can have an entire average pallet broken down and rid of all its nails in less than 15 minutes without breaking a sweat. Enjoy!
