Hi Carl, Your diagram didn't come through but I think I know now what you are asking. I assume the top curved rails are arcs of a circle. If you know the length of the chord AB in the diagram below and the height, CD of the highest point D above the chord then I can calculare the radius of the circle and work with that but there might be an easier approach. Suppose there are $n$ pickets counting the two at the edges of the gate, then there are $n  1$ spaces between the pickets. Measure the length of the rail from $A$ to $B$ before you bend it. Call this length $L.$ Divide $L$ by $n  1$ to find the distance between the holes. Drill $n  2$ spaced $\large \frac{L}{n1}$ units apart. Do you think this will work?
