Is this what you are trying to do? If it is, I first drew a horizontal connected line with vertices spaced at 0.75 - 0.75 - 0.75 - 3 snapped to a grid of 1/8 spacing. Then I lifted the second vertex to the 0.75 to make the triangle. Then I converted the last line segment into an arc and lifted the center of it to 1.25. Then I drew the 3/4 circle in it and made it a cutout. Then I copied, pasted, and moved the whole creation over and over to take up the length of the board. With everything selected, I tweaked the overlapping vertices to connect the whole path together and then made it a cut path.
