I only just thought this idea up but it should work, it is how I would try it.
Once you have the first part of the spiral started you can make a guide to attach to your router at exactly the right distance you want the lines apart.Put the guide into your start point and it should follow round and round in circles to create a perfect spiral.
Hope this makes sense
