I'm building a cedar pergola and was cutting decorative tails in my beams this weekend that are 2x12x16. I was using my circular saw to make some angle cuts by setting a speed square to account for for the offset of the blade from the saw's base plate. Well, on my third board I stopped paying close enough attention and accidentally started cutting from the wrong direction (about 5" different blade offset) and ended up cutting about 2/3 up the board before realizing the cut was too deep.
Is there any way to correct this screw up that won't be noticeable? I'm staining the boards with a semi-transparent stain in a natural cedar tint. There won't be a structural issues as the cut is starting from what would be the bottom of the board and it's not bearing any additional weight near the cut. I was originally just going to scrap the board, but they're fairly expensive ($115 locally) and require a pain-in-the-ass drive to get.
