Japanese ink pot.
This is part two of the Sumitsubo blog.
This is where we ended last blog.
What I do here might seem destructive to some.
I dye the Sumitsubo black.
Why? Because it will be used with black ink and I then will not have to worry for stains later, and also I think it will be a beautiful contrast to the light colors of the plane bodies.
Color the wheel and smoking the pipe.
Hanging to dry.
Here the handle.
Then some layers of shellac, I think I gave it five.
Adding it with a cloth in thin layers.
And sanding in between.
And here we are.
I banged the rod for the handle a little flat where it was going through the wheel, and put some clay epoxy in the wheel hole before I mounted the handle.
It seems to work.
I don’t know about you, but I really like it.
So my ‘stuff’ arrived from the shop.
Silk line – Tsuboito.
Ink – Sumi, here in the form of chips.
Bamboo Marking Pen – Sumisashi.
(Yes I should have made my own, but I have no source for bamboo – sorry).
I also bought a Japanese square.
(Cord for my frame saws and two extra wheels for Veritas wheel marking gauge).
I rolled up some silk line – Tsuboito, remember that 7-10 meters should be more than enough for most tasks., in fact 3-5 should also do it, and I have 72 meters here so enough for the rest of my life.
On my lathe I turned this little fish shaped Karuko
Added a broken drill bit that I grinded pointed on a running dish sander while it was spinning in an accu drill, but this can also be done with a file on a drill.
Big fish – little fish.
The line is fastened to the fish and then you make a loop around the pin.
Time for the wadding.
App double than the size of the pot.
Make half of it wet and place it in the bottom of the pot.
Let the line run over.
Add ink chips.
The rest of the wadding on top.
Make some ink by grinding some ink shaves and dissolve it in water. (or buy pre made water based ink)
Eating the big fish…
A little water on top.
So we are ready to use it.
Put the Karuko in the one end of the wood you want to mark.
Run the line to the other end.
Lift the sting and snap it down.
Then you will have an ink line on the wood.
It can also be used for marking with the Sumisashi just as we would use a pencil.
Ink line (I need more practice or more ink…).
The square Sashigane is shaped so ink will not get trapped under it (it’s rounded up).
And this is where this blog ends.
With a picture of my new Sumitsubo ready for future projects.
For me this has been a really interesting tour in the Japanese world of tools, I will continue, and continue to share it with you.

Hope this blog can inspire others to make a Sumitsubo, or perhaps just to have been an interesting reading for someone interested in the Japanese tool culture,
