You may have seen this video, but I just came across it. Nice music, very calm approach, very good camera work and lighting.
My longest-owned plane is just like the one he tunes up, and I can't say whether I am inspired to try the same on it or not. I know for sure I could not do the new washer thing he does for the adjustable mouth. He has a nice old metalworking lathe, and I don't.
I really like the look he achieves with the scraper tools. Much better to me than machine-ground surfaces.
