From the why didn't I think of this first file.
I was trying to square up the base of my circular saw and after filing it for a couple of hours it hit me to use the conical sanding disc. I now have the sides straight and they are parallel to the saw blade. The saw follows a straight edge much better now.
I have an inexpensive Craftsman and the base won't remove from the saw without hammering it apart so I trued it up with the saw and motor still mounted on the base.
First check to see if one of the edges of the circular saw base is close to straight and reasonably parallel to the blade. If neither of these conditions exist you will have to mount the base on something straight like a piece of plywood and set it so the edge is parallel with the blade (double sided tape would probably work). Otherwise you will need to file one side straight and parallel to the blade.
Make the first pass (very thin) over the conical sanding disc then check if it's parallel with the blade, if not readjust everything or you can file one end down.
Take several thin passes until the the first edge is finished then turn it around and true up the other side.
I had to use a plywood spacer to go between the Shopsmith fence and the circular saw base because the motor wouldn't adjust high enough to clear the fence. On the motor side of the base I had to raise the SS table way up so the Conical Sanding disc didn't hit the motor housing of the circular saw.
Now when I have to take my circular saw and cutting guide with me to the lumber yard I can get a straighter cut. (Not all lumber yards have panel saws)
