I bought a Stanley #48 in good shape to cut tongue and groove joints. This is my first joinery plane of any kind. It has one small blade and one wide one. They were on the wrong sides and really dull when I got it. I sharpened the blades at 30 degrees and reinstalled them on the correct sides.
One thing I'm not sure of is how to set the blades? If I bottom them out in the groove, they slightly overhang the shoulder. If I line them up with the shoulder, they don't seem square. Also, how far should they project and what's the easiest way to adjust the depth? When I did some test cuts, the joint works, but is slightly loose.
