Cutting boards are a valuable, and, at times, under-appreciated kitchen accessory. In this plastic age, we have been overrun with sick, milky-white slabs of questionable origin, claiming to be safe and clean. After a few weeks, you end up with a scarred, savaged scrap, un-saveable, collecting crud in all those crevices. The alternative? A solid, reclaimed hardwood cutting board made from old flooring, hand-rubbed with tung oil to a high, non-toxic sheen. In a pinch, it's solid enough to chock the tires on your inlaw's RV, or knock a kitchen intruder unconscious. It's also cheap (nearly free!), beautiful, and can be continually refinished, lasting for generations.
I put this cutting board together with oak and maple floorboards pulled from old Chicago bungalows. Save what you can from alleys, building sites, and salvage shops, get some good glue, and set aside an afternoon. If you are lacking some of the heavier equipment needed -- thickness planer, pipe clamps, router -- you could laminate it together using the technique found in this table I did a few years ago: https://www.instructables.com/id/Scrap-Table/
You will need these materials:
Reclaimed hardwood (not laminate of any kind!) flooring
Waterproof wood glue

Step 1: Preparation
The first step, key to safety throughout this project, is to thoroughly de-nail the floorboards. One nail can chip teeth off of a table saw blade, ruin a planer cutterhead, or fly up and take an eye out. Go over the boards carefully and remove all nails and staples. If you have a metal detector, use it. Zircon, maker of stud finders, makes a handy pocket-size metal detector that is handy for this sort of thing, as well as finding wires in walls, rebar in slabs, etc.
