So if it’s now fixed, I think that loose metal tab suggests that there could’ve been a little bit of play in the entire mechanism and while soft wood may not have presented much resistance to the cutting iron, when you tried hardwoods, they probably had a more jarring effect and probably was jarring the frog backwards a bit, causing the iron to retract ever so slightly (we are talking thousandths of an inch in shaving thickness so it probably didn’t take much)…
So, assuming the problem is now “solved”, I guess the lesson was just to make sure ALL screws on the entire plane are as tight as they should be…the 2 frog adjustment screws that seat it–when Paul showed how to do them, he tightened those very tightly and then backed off of them ever so slightly so as to allow minor frog adjustments if necessary. But yeah, if that back tab was not firmly in place by the screw, that could certainly allow for some frog movement…
So you’re good now?
9 March 2017 at 8:38 pm #309992Perhaps it was a mix of the lose screw (I didn’t quite understand, which one), the micro bevel and the frog sitting slightly askew. On your second and third image, I can see the frog protruding a bit forward on the left side.
On the images of the sole, the toe and heel are quite obviously a bit flat. And it seems, that you have a hollow from “8” to “40” on the scale of your ruler, last picture. It could be the light playing tricks on the camera, but you should check this. The flat areas on heel and toe are of course due to “natural” wear, but will take more time to take out, if you wait longer. The hollow area might hint to more ondulations in that area.
However, I am sure, the main problem is the shape of your blade and bevel(s). Although, another problem might be the shape of your board. Have you tried on another oak board, or even just the other side?

@hugonotti I have successfully planed off several boards now l and all is well. The hollow in the picture was created by the light reflection from the camera. It’s actually dead flat unless my square isn’t but I check my square regularly and know it to be flat as well.
10 March 2017 at 6:09 am #310000That’s great! Glad you got it working. Still I think the issue was the blade geometry. Since all issues with the body of the plane would have resulted in inaccurate planing, rather than a non-cut.
And it’s not a hollow but a belly that I see in the picture. Just judging from your description of the symptoms it sounds like something I have dealt with often while learning to free hand sharpen, which I still believe is faster, though not at first because it’s really hard.
Glad you were persistent and made it work.
You are most likely correct on the improper sharpening. Sad thing was that I ended up doing that 2-3 times. Havent had it happen to anything else I sharpened.
Must have been a brain fart. I have been sharpening free hand my entire life (since 10 years old anyway) so you think I could have done this right.
Granted the plane blade is different from a kitchen knife.
