Remember Safety First. Always read and follow the instructions that come with your router. Wear safety glasses when working with all power tools. Routers generally work better in one direction over the other, usually counter-clockwise or right to left (read the instructions). Make sure that your "Circle Making Jig" is securely attached to the router and firmly nailed to the centrepoint of your corner radius.

 Try a practice curve on a spare piece of wood first (see Handy Hint #3). Generally, you should make one forward pass to cut the groove and one backward pass to clear out the debris/cuttings from the slot. Any more than that and you risk messing up the slot. Remember, always cut the corners first, and then join them up with the straight-aways. Don’t route your curves too far.... the curve should stop when the radius line is at right angles to the straight-away. This makes for the smoothest transition between curve and straight.

 To cut the straight-aways, remove your trusty "Circle Making Jig", place the router in the end point of one curve that has already been cut, nail a bracing board (1" x 2" x 6’ or similar) securely to the table and just touching the base plate of the router. Hold the router steady, power it on and just run the router in a straight line, against the bracing board down the table towards the next corner. The bracing board will have to be lined up so that the router groove meets the next curve. If it doesn’t quite meet, see section "How to Fix Any Routing Mistake".
