I'll record the first shape of the Yumi.
What to prepare.
Yumi
Tsuru
Camera or Smartphones
A point to keep track of when you buy a Yumi.
See the video on how to attach the Tsuru.
See how to attach the Tsuru.
If you have flooring, place the Yumi so that it overlaps the line of the board.
If not, place a string to mark the spot.
The first thing to record is the arch of the Yumi.
Check to see where it bulges out.
Check the whole thing and make sure that this width does not change.
Check it out after you draw your Yumi. Check it every time in the beginning.
Points to make the Yumi less deformed.
The Tsuru will be installed on the right side, not the middle.
If you continue to attach the Tsuru in the wrong place, grooves will form and you will not be able to correct them.
If you only use your hands to support it, it will look like this.
You can see that Tsuru is on the right side of the Yumi.
If the shape of the Yumi changes, the Yumi will become weaker and the Ya will not fly straight.
Let's be careful not to change the shape of the Yumi.
Thank you for reading to the end.
