So I came across some old library tables and I am going to use the tops for the tops of the workbenches that I'm building. They are solid maple 1-1/2" thick. I sanded one down to bare wood and cut it to size. I'm pondering what to do about a finish on them. I have been thinking about just using butcher block oil on them rather than a poly type finish. What have some of the members here done for their bench top finish, any suggestions?
