Well, there is a lot of good stuff on this thread pertaining to pallet projects. I am glad to hear you are finding some inspiration.
Also, Thanks for sharing your photos on your pallet coop build. Love it.
Most of my pallet projects use wood from pallets I breakdown and reuse. There are some suggestions in this thread about tools that will help speed up the pallet breakdown process. Some people manage to use full pallets without breaking them down. That would save a lot of time.
If I can use full pallets, without breaking them down, then that is what I would do. But, I'm all for taking the extra time to get the wood in a form that I need for my projects, and I don't mind (much) if it takes me a bit longer to complete the build. I just think about how much money it would cost me to build that project with new wood.
