Hi all-
I just purchased the Lee Valley side rabbet plane. The directions explain about docking the point of the blades so they don't dig into the bottom of a dado or groove. I understand this - but what I'm confused about is that the amount the tip protrudes is a function of how deeply the blade is set to cut. So it seems to me one has to decide on a specific depth of cut and stick with it. Once you grind off that tip, if you set it less deep, the blade won't reach the bottom of the side wall and if you set it deeper, it will dig in again.

Am I misunderstanding this? It seems odd to have a situation where you have to choose a single depth setting on a plane and only use that.

Thanks!
