I have an early type Stanley 8 that needed a new chip breaker. I just went with the LV combo and bought a blade too. Very nice, heavy duty, great finish. However, its a bit thicker than the standard. I have moved the frog back as far as it will go but I still can't get it to project. The opening stays filled no matter how I adjust things. Should I be having this trouble or is it common for these blades to require plane fettling?
