Here is a simple system I came up with for duplicating the function of the parallel guides. Everything is off the shelf parts that you can buy and only one small modification is needed. One feature I like about this is that each guide rail sits on top of the piece of wood so nothing is hanging down on the sides like the Festool set. I used it this weekend and it worked out great. I know it is not as nice as the real thing but it worked great for making a bunch of accurate repetitive cuts.
