This is the collection of photos showing the final progress of the ball chair. It consists of photos of the template and the p rocess of assembling the chair. So glad that it is finally done!
After several tryouts of different types of locking, i decided to go on with this one. Although my first aim is to have the chair as a seamless piece without the locking appeared at the surface of the chair, it seemed quite impossible because it won't hold the chair strongly. Therefore, this final locking system will be done from the outside of the chair instead of the inside, thus giving more strength.
After my first attempt of 1:1 scale chair failed, I reviewed the locking system and made some changes to it. I changed the template so that it is easier for the parts to join. And I tried to use another method of locking system, but it's not working really good because of the scale is too small.
Here is my first tryout using Xanita board in 1:1 scale. After spending few hours i managed to cut the template and V cuts.

Locking System
After that, life gets tougher! assembling the template was so hard. Xanita board is hard to assemble when the angle and measurement is not correct. But I managed to get the first side done.
Trying to lock the parts up
First side assembled
Then, I managed to get both side locked up though not very nicely done. I thought it was really good on my first attempt.
Next, is the inner part of the chair, this part is a supporting role to the chair so that it is strong enough to hold someone weight when it is seated.

When it is done, it is placed in the inside of the chair that I have assembled.
Inner side of the chair
Sadly, some of the angles of the V cuts weren't right and the worst part is that the locking system is not strong enough to hold parts of the chair when it's pulled together. I had to use tape to make it stayed and you can see from below pictures, the locking system is too tight and pulling out.
This is one part of the chair, there are four sides with this type of shape. So, to get the shape i want, i have to make V cuts on each side so that it can fold properly.
Here is my first attempt :
First Attempt
I made the angles too big so all side did not come together closely as you can see there is gap in between.
Here is my 2nd attempt :
Second Attempt
In 2nd attempt I successfully made it :). The V angle was smaller so all side are coming together as one.
