Last night, I followed the advice of this fellow with a #4 Stanley. I actually did it in reverse order, but the results were the same. That #4 Stanley cuts fantastically and *easily*. I was surprised how easy it was to push through the piece of pine I had nearby. Listening to it cut, the note it sings is quite a bit higher than it was before.
Mating the frog and the plane body was the tedious part, I actually had to remove quite a bit of material to get the front of the frog to sit firmly on the body. I guess I could have shimmed the front of the frog, but I didn't think about that last night. When I got done, the frog screws were bottoming out before they secured the frog so I had to install a couple shim washers.
One thing I did that he didn't mention was I put a few drops of oil on the adjustment screw threads and the yoke. That made the action SO much smoother.
