x-board number 2

X-board number two and final. I think I have it all figured out. Eight or so more hours and......

We get this. I'm almost positive that the piece of board I got wasn't cut square, so all the fold channels were extremely difficult to do. When I folded it together the edges were floating off the ground. I was pretty pissed off. I had to hack at it many times to get it all to fit together. In the end this is my final product, I vow not to touch it again and can't wait to never have to look at cardboard for the rest of my life. If I do I will cringe at the thought of these last few weeks. 

Oh and the arms didn't work again for some reason. I cant work it out. I seriously think its the x-boards problem as it is exactly the same as my other 1:1 and it works on that. If I had a chance to make another one...... I wouldn't. 

I cant even judge anymore whether it is a nice looking chair or not. I have looked at it in anger for so long that my vision is impaired. Hopefully it works and you like it. Its super strong as well. 

x-board number 1

So I am ready to make my x-board model. Or so I thought. 8 hours later and wella...... a chair that is NQR. ( not quite right, for those unfamiliar with the lingo)

Don't do this at home. My hairdryer was nowhere near as industrial as the workshop one and I got extremely frustrated. Extremely!

As you may or may not be able to see, there is tape on the top of the back. This is because it was ripping more and more every time I folded it. Another thing I will need to resolve in my next 1:1. 

When I was cutting out the arm folds I had convinced myself that the 1cm channel would fall below the line. I was tired. and wrong. Therefore It was time for another 1:1 x board. damn. 

fixing the arm....

In my 2nd 1:1 mock up I thought i had resolved the arms. turns out I didn't. as you can see below. 

The bottom of the arm didn't meet up with the top of the seat as I had thought it would and the angle of the corner didn't meet up with front part of the arm. 

To resolve this i took another piece of cardboard and and drew out where it should go on my model. You can see in the bottom three images the new arm that fits and the flat version is the last image. Fingers crossed this will translate into X-board!

final design

I re-figured out all my angles according to the design tweaking I did and now have finalised the flat design to go onto my xanita. Finally. Here it is....

folding methods

I will also use the 45 degrees angles inside the x board to create my corners. These degrees may need to variate to accomodate my unique angles for the triangular arms. 

refinement

From my last 1:1 model I worked out a few things. The first being that as it stands the seat doesn't feel quite wide enough to sit on (currently 400mm). The second being that the angles of the arms don't quite work. Both of these things can be fixed easily. I will pull the edges of the seat out further and create a locking system under the seat system then make the seat itself slightly wider to make it more comfortable. I will then re-calculate the angles and sides of the triangles that make up the arms. 

The next thing I will need to work on is the folds in the x-board so that they all fit and fix properly. 

1:1

I made another 1:1 model out of one big piece of card. This made it easy to see how the folding chair would work. The angles were calculated using trigonometry. When folded together the arms still didnt fit together quite right but i think I just did the angles on the opposite side of the protractor. This can be easily fixed and I will draw up a new flat pack plan according to these angles.
