Instead of relying on precise measurements from your straight edge guide to your circular saw blade and then transferring this to your work piece try this instead.
- First clamp your straight edge guide to a scrap work piece
- Draw a line along the “guide” side of it
- Make your cut using your circular saw
- Cut off the piece on the other side of the line you drew
Now you have a story stick that can be used for every set up which will give you the exact distance needed from the your straight edge to the cut as long as you are using the same saw and blade.
