I am not exactly sure what you are arguing for or against now, Tom.

For all those people who don't have expensive new planes, this new turn of events is a godsend. It finally makes their humble Stanley #4 or wooden coffin smoother performing the way it was designed to be. Of course the information has always been there, just not very explicit. And their have been enough naysayers to the virtues of the capiron to make the most stuborn tinkerer doubt himself. You mention Larry Williams, he is a prolific figure and it turns out he is plain wrong about the capiron.

For me the eye opening thing was about the numbers. I saw 0.1 to 0.3 mm mentioned in the video. So I meassured my fine tuned chipbreaker and found 0.4mm. At that moment I realised that I had to go closer and suddenly everything clicked.
