I bought a bunch of these at the local Habitat for Humanity store the other day. Thought I would make a butcher block with them. I have no idea what they are or what they were for, but they are all hardwood. The issue is, as you can see, each one has the corners chamfered. I will need to mill these away to glue together with no gaps. They are too small to do anything safely with them on the jointer or table saw. Only thing left is band saw or hand plane and I'm not that proficient with hand planes to really get them square. Whats the best way towood blocks 2.jpg square them?? Randy
