Hello Martin,
In order to understand how to do, I am looking into building a scissors crossover from design to lasercut. So I started to read Archive topic 465 from John Preston. All the steps I have done can you find in the word document. Also I added the box file. When I look to the final result in the figure below, the exercise looks rather okay, I thought, although it just fits because of the minimal adjacent centre distance of 44,67 mm I used. But there is a small problem and I don’t know how to solve this in a proper manner. The problem is that the inner track doesn’t fit exactly inside the pie slice determined by the radius and the angle made by the outer track. The rootcause is of course that all turnouts are the same (N=8) where the inner turnouts should have a bit smaller radius and factor N. ... and this causes again that I cannot put the timbers in both the upper left as right area opposite to each other. Do you have an idea how I can solve this?
