The Sticker gives you a graphic of the bit you are using, stuck onto the Router Plate. Against it on the Guide Rail, you set up a picture of your workpiece.
As the real bit moves across the real workpiece, so the Flightpath Sticker slides past the picture of the workpiece on the Rail, telling you exactly where your cut will come – its path through the wood and the width of the cut.
Most often you will need to know where the edges of the bit will come and place them against a line. We did consider a laser beam centre finder, but it was expensive and did not tell us the exact width of the bit... a bit of a gimmick.
Our sticker doesn't cost five dollars and it tells all.
With the Guide Rails in place:
Place a half inch straight bit in the collet and a piece of acrylic against the machine face and Lock it in place under the bit. Bring the bit with blades North/South gently to the acrylic. This places the bit diameter at the machine face. Lock down the router plate
Place the sticker on the Router Plate:
use the same acrylic slat, but flat on the Guide Rail up against the router plate, so that when you peel off the sticker backing, you can line up the sticker exactly against the edge of the plate. It could be best to place the sticker on the tip of a knife blade and slide it in place against the acrylic, before firming it down. The exact position is not critical but it’s best if the centre line of the Sticker is just in front of the countersunk hole in the Guide Rail then the hole is not in the way of the drawing.
The real half inch bit at the machine face is represented by the larger of the three half circles on the Sticker. You can now mark the face of the machine on the Guide Rail by continuing the near half circle as a straight line across the rail. Now the picture of the half inch bit on the router plate is touching the face of the WoodRat on the rail. Use a sharp pencil.
The line on the guide rail now represents the machine face. Unlock the router plate. It will slide up and down against the machine face line on the guide rail just as the bit will travel forward and back over the machine face and past or into the wood.
Put the back of your workpiece against the line on the guide rail and mark the front of it on the guide rail. Place the workpiece under the router in the Cam Lock.
Now as your Sticker moves against the picture of your workpiece, so the real bit moves against the real workpiece. You can tell exactly where the bit is: whether back safely behind the line or in front of it ready to cut.
The “fir-tree” graphic will give you the centre of your workpiece. Line it up symmetricallybetween the branches, you can now cut on the centre line.
To take three millimetres off the workpiece, mark 3mm on the workpiece on the Guide Rail and bring the cutter half circle to that line, and cut.
The Sticker is permanent, but if it is not accurate enough in practice, you can remake your pencil lines on the Guide Rail. It can also be used together with the Block and the Stops over on the left-hand guide rail. so that you do not have to refer to it at each cut when doing repetitive work.
