Second Hand Blender Ⅱ & Ⅲ(Final)

Day 2 (20.5)
In this morning, I added the materials and completed the freefall mechanism. This structure is used three arms that is attached to the motor, get hung up and pull the string.


After this, I was adjusted length of the string and speed of the rolling while changing the chopping item(a spanner→a hammer→a knife).
I didn’t think a knife was made with itself really! After cutting a board of iron in the shape of the knife, I shave one side with a file and make it sharp. Sparks flew and the power was necessary and the iron became hot and was serious… But I felt like becoming a sword craftsman at all, and it was exciting.


A goal on this day was achieved for the time being, so a machine was operated!
The very first cut was mushroom from David. The knife was the good sharpness, so mushroom was shattered in no time.

This day ended here.
A target in the last day try various food, and do last styling.

Final day (22.5)
The first task was to buy a lot of fruits at a supermarket, before coming to Time’s Up. When I tested the machine at last time, fragments of mushroom had been scattered about here and there, so I decided to make a cutting board with barriers. The cutting board was designed with a good angle for rolling and entering the fragments to a dish.
It was difficult to cut a wood with an electric handy saw of holdings straight. An electric file was very convenient to arrange that.

The height of the machine was raised about 20 centimeters and it was tested.
An orange, apple, a kiwi, pear and strawberries wich bought in this morning were put on the cutting board, and switch-on!


It was crushed in a moment. Quite fearful blender…but, nice fresh fruit salad had been finished. Taste was good!
I made a sign of “ASUMI’s KITCHEN” in the end and my project was completed.

Then, presentation time was coming.
I explained the mechanism while cutting fruits actually. Many people enjoyed a movement of a chop. I also got the opinion that a knife seems to be a Japanese sword from several people. I think that it was especially good to made knife by myself and angled a cutting board so that cut food may be heaped on a dish finally.

There was a chance to learn “how to use the tool” by a course of a goldsmith and a carpenter several times up to now. But the experience obtained is entirely different and more powerful to learn by the viewpoint to which “how to construct to make the objective movement”, so this workshop was so good experience for me.

Second Hand Blender Ⅰ

Unlike today that is everything efficient, This blender is not convenient.

If you want to drink juice, you have to wait foods to be ground up as like the hands on the clock advance slowly.
When the machine work, an ax or hummer is swung down and foods are chopped. Foods are in bowl and the bottom of bowl has the hole for juice to drop off. After you wait patiently and foods is clashed, juice flows out.


Todays goal is make the structures that arms go up and down using rotation of motor.


First, I find just right metal materials, and then cut and weld those to make the moving arm and the frames fixing a motor.
I also assemble more one frame and succeeded to make them move the sinker put ahead of the string up and down.
But this is in the state which just still moves by uniform velocity, so It’s necessary to make another frame and make the structure of free fall with the next step.

I use square frame for the structure of free fall because it’s suitable to rotate arm freely and stably. For the arm, I use aluminum plate (it’s light).


Next time, I will finish to make the structure and if I have more time, I want to try to chop some fruits.
