Tips and Jigs Part 1: Circular Saw Straight-Cutting jig

Step 5 Make the guide for the saw

I took 2 pieces of scrap poplar and cut them to the length of my already cut panel. I used my router to trim away some material for the guide, but you can also just use a shim to create the offset. I opted for the router because it was set up and I thought would give me better result.
I used some other scrap to get my fence gauged right. I make the cut such that I created a shelf in the wood that was as deep as the thickness of my aluminum angle.
