Hi Steve,
First, click on the 'lamination' button to display the laminated board and then click the 'details' button. This shows how you set your miter angle to 25 degrees and then make a series of identical cuts so that each of the strips is 1-1/8" wide. Then take two of these strips and flip one left-to-right and put them together to from a V pattern (a chevron). The chevron is the repeating unit and it consists of a left strip where the pattern declines and a right strip where the pattern inclines. Do this with all the remaining strips and glue them together in a series of chevrons and you have a first generation (chevron) board.
If I understand correctly, you then want to make a disk from the 1st generation board using a total of four repeating units. Now, while this is not difficult, it is an intermediate task in terms of difficulty.
To do this task, click the 'radial' button and this will show you where your cuts are to be made but I will elaborate. First, take your first generation board and then draw a line from end-to-end right through the center of the board. The center is measured is half-way from the top of the 'ears' to the bottom of the bottom ears. For a four-sided disk, your cuts will be made at 45 degrees and the cut must go exactly through the point where the left edge of the repeating unit (chevron) crosses the center line. You can then either flip the board edge-to-edge and make the next cut through the other boundary of the repeating unit, or you can not do any flipping and make all the cuts in the same direction, skipping every other repeating unit and then come back and make the other cut.
The 'radial' button screen shows you exactly where these cuts are to be made.
Finally, you'll notice that the top segments have a different pattern than the segments on the bottom. Your intended design is made by using just the top segments and another design can be made using just the bottom segments.
I hope that helps.
Lloyd
