I made a checker board using my Ryobi Router and Ryobi Drills. I first glued together douglas fir boards with a biscuit jointer then I made a jig for my Router to fit in. This made the router slide in a straight line to make the squares. I then turned the circle over to make the 1/4" grove using a 1/4" straight bit on the router with the base guide. This was to accept the 3 pieces of pine board that fit into the bottom of the pie. Woodworking is something I always wanted to do more of and Ryobi Tools has made it posible with there great quality in there tools with a great price.
