Japanese scraper plane
I posted the plane quite some time back (July 2011), but forgot to post the blog…
So here it is finally.
Time for learning a little Japanese…
A symbioses between a Japanese Tachi-Ba-Kanna (standing blade) and a Krenov style scraper plane, made for the purpose of tuning the sole of Japanese hand planes.
I have now also build a Naga-Dai-Kanna (Japanese jointer plane) in this style: http://lumberjocks.com/mafe/blog/37783
My kind sister brought me some Japanese chisels and a plane from her travel in Korea and this inspired me to look a little into Japanese tools. So while on holyday I read the book The care and use of Japanese woodworking tools of Kip Mesirow & Ron Herman (not so impressed) and the wonderful and so inspiring book Japanese woodworking tools their tradition spirit and use by Toshio Odate (please read this book) and now two years later a few more books, this one the last inspiration that goy me going: http://www.e-hon.ne.jp/bec/SA/Detail?refISBN=4416809115 .
Here the plane, a scraper plane, made for setting up my Japanese planes.

The project started out with some staves of Ash from a old table top.
On table behind you see the iron I was thinking to use, but this steel was to hard, so I could not create a burr.
Fist the opening for the mouth here set for 45 degrees.
Then the bed for the iron.
This cut on the opening gives a stronger edge and allows tuning.
I decided for a big mouth opening, so that it was easy to look what I was working on.
Don’t know if there are some rules for this.
Then cut to length.
Slicing up pieces for the sides.
Here we get the picture.
Some glue and the Krenov magic begins.
Clamps, never too many!
Here I also am able to clamp down.
After drying, this is what we got.
So cut to final size.
Flatten the sole.
Braking the edges.
Making the wood for a wedge.
Now it all starts to make sense.
And a cross pin for holding the wedge.
Actually the Japanese scraper planes are not made like this, just as the normal planes, the iron is wedge shaped and clamps it self into the plane body this way, but here I use a Western iron, so I have to be creative. Also I try to hold the style of the Japanese planes this way, since they use the pin for holding the chip breaker.
Then its just to drill the holes for the pin.
Bang the pin through.
Dai-Naoshi-Kanna making shaves.
The iron I had selected for this project is laminated, with a hard steel on the cutting edge.
So a tour on a diamond plate.
And correcting the edge, but finding out it is much to hard a steel to ever be able to make a burr, the steel will break before bending.
So I cut up a cheap block plane iron I had in the drawer.
(Not as sexy, but softer hardening).
Giving it a burr.
Then I cut down the plane body, this only for the sexy factor… I thought it looked better and would be more easy to control.
Giving it my mark.
MAFE tools. ;-)
Finally making some super fine shaves, it can go from dust to shaves, depending on the burr.
Kind of Japanese or?
I think it will do.
Now ready to help setting up the rest of the planes.
A few more planes have arrived since, and the Dai-Naoshi-Kanna have been a friend to them.
Hope this blog can inspire to some tool making, after all, the tools you make always become special.
