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:

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: .

Here the plane, a scraper plane, made for setting up my Japanese planes.
You can read more about tuning Japanese planes here:

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.

Wonderful work! Quick question, do you see any pros/cons of building the dai from a solid piece of wood vs a Krenov build? Thanks.

Great work Mads. I am learning to love hand planes and hand planing. I will probably stick with my Stanley/Bailey and bedrock design planes since I have already laid out a fair amount of money for them, but that certainly does not stop me appreciating these fine Japanese style planes you are creating. I like your hybrid versions too. That is how designs progress and change, so a natural progression. All good. Keep up the good work my friend.

SirFatty, That is depending on your skills and tools, I think I can build one in a hour or so and then the glue drying time. When I build my first Krenov I probably spend a day, with only hand tolls I’ll say half a day. Hope this brad answer helps.
Siavosh, The answer is no. I know some that will say different. Some say it is only a Japanese plane when cut in one piece, this is like saying a Krenov type plane is not a Western plane. Some say the glue might not hold, as an Architect and house builder I will say there are no problem what so ever. As an Architect of course I can enjoy the beauty of a one piece wood plane.
RobynHoodridge, I am retired – lol – it is all pleasure now. Thank you!
Mike, I think you know by now, that for me it is not the need for planes, it is passion, I have more planes than I can ever use, I love to study them, to tune then, to challenge them, to find out the differences, the ways, the builds, the designs, the patina, the different types on the planet, the sounds, the smells, it all – I am a rhykenologist and a happy monkey, curious as a child and passionate as a lover when it comes to planes. God help me!

Good to have you back posting again Mads! Hope the next few weeks go by quickly and you can get back in your shop. These Kanna builds are timely for me as I have a toothed iron I want to use in a wood body plane.

Dough, it is easy, ‘just do it’, I have learned woodworking is all about that.
Jim, I try my best to show it all, even I do forget and sometimes have to go back and take new pictures…
Philip, on my hard drive there are plenty, so lets see. ;-)
