With trial and error you will find the solution without a doubt, because you there a 5247 possible ways to arrange the discs. You can make the puzzle more difficult to add some restrictions: It is forbidden to put two pins on each other. Now you can find 66 solutions in total. 

Making this puzzle is not difficult, but you have to drill the holes very precise. If you make the discs you can use a special drill to saw round plates, a so called 'seven hole drill'.
