What tools should I use to remove the tongue and groove from floorboards?
First, a disclaimer: Make sure the wood you are going to use will stand up in the environment you're placing them in. You may be better off using these with the T&amp;G on an indoor project. Weather outside will quickly weather non-pressure treated wood, and decks typically require thicker boards than you'd have inside since they don't have a sub-floor.

For long cuts along the length of a board, the best tool is a table saw. And the second best would be a circular saw with a jig. If you don't have plans for more projects like this, or simply need to save space, then the circular saw makes more sense. Setup a jig with a long straight edge that you can run your saw along and clamp it on top of your boards to be cut.




To smooth the edges, a router would be best. You could also use a block plane or sander. I'd be tempted to get a belt sander to make this project go quick and to give me the chance to cleanup the finish on the boards at the same time. A small orbital sander would also work and have other uses around the house, but it would take a lot longer and wouldn't be as useful if you want to cleanup the finish on the boards.
