Here is a butcher block that I made for someone out of Maple, Mahogany, and Walnut. This one took longer than I thought it would. The boards were twisting quite a bit when I was cutting them out to their rough size. So I had to make sure to flatten one side for each of them, then plane them to final thickness. Once I got that down, then I was able to square them up on the table saw, clean up the edges, then glued them together. I finished it using Mineral Oil which is food safe for butcher blocks.
