I just picked up a new replacement iron from LN for my old Stanley #7 bench plane. I honed it up and put it in the Stanley. Now I have developed and issue I didn't even think about. The iron is now to far forward in the mouth and actually just bumps the front edge of the mouth before it pops below the sole. I'm sure this is a common issue but one that I am not real sure how to fix. I tried adjusting the frog a bit back but can only go so far before I loose a good seat of the iron to the frog due to the back side of the mouth opening. Is my option to file the front edge of the mouth until I get the clearance I need? Is there some kind of tips in doing this or a tutorial I've missed somewhere? I know this has got to be the right place to ask this question. I was pretty dissapointed to find this out as I was really looking forward to using this plane more with an iron that is actually useable.
