I have handled my fair share of pallets over the years working in warehouses, the ones I’ve worked with were strong, but splintery, I suspect this (and any other pallet wood projects) would require lots of sand paper and elbow grease, but I’m also sure that they would make strong structures if you plan carefully.
This guy built his tiny home (almost) entirely out of pallet wood and other recycled materials. I love that he has the story behind every piece of material he used. Enjoy these two videos.
