You will read elsewhere that the scraping down of the sole is to reduce friction, which it does, but it does a lot more than that. The proper relief is what causes the wood shavings to actually leap out of the plane mouth as you plane. You can tell when your plane needs a bit of adjustment when it only works as well as a "normal" western style plane. Not to dig, but for me this is true. I still use metal body planes on occasion because they are so easy to use and, if well tuned up, will give good results. I don't feel that I am particularly good with either, in my opinion. To see some people work...........wow.

The question is, how much do you alter? I hate to think of myself as a tool collector (##$@@#$), I just want a nice tool to use. I want to respect the intent of the craftsman who originally made this, so I think that to alter it enough to make it work well and be a pleasure to use, that has got to be a good thing karmic-ly, right?

The last thing that I do is to freshen up the chamfers on all of the edges except the bottom front and back. Those stay square.
Two more rounds of scribble, oil and scrape get us a good snug fit that barely protrudes out the bottom of the dai body.

And the proof?
I am not some great pro or anything. Admittedly, I got really lucky with this kanna. It was a very good tool to begin with and wasn't in too bad of shape. I'll show some really rough ones in future posts. This took a total of about 2 hours or so of relaxing work. You really get to know your tools this way. If you are a set-it-and-forget-it kind of person, this obviously isn't for you. If you don't mind a bit of fiddling, you can do some really nice work for not a lot of money. This kanna looks almost new now and performs really well. I may still fit a piece to tighten up the throat, but for now, I'm happy.
