I am relatively new to woodworking. Has anyone used hardwood flooring as material? I have access to scrap hardwood flooring. My wife works as an accountant for a hardwood floor installer. I have been dumpster diving for years but typically used the wood for my fire pit. I started thinking that maybe I could buy a planner and mill down the planks. The problem is that the wood is really hard. I am thinking the material may dull blades and not be very good to work with. Any ideas, comments or suggestions?
