I made a balans chair referring to Varier Variable balans.

You have to prepare
- boards 18mm thick, over 530*500mm
- a CNC milling machine capable of cutting over 530*500mm

Step 1:

Please download a zip folder.

balans4share_ai.zip contains ai files (I made them with CS3),
balans4share_pdf contains pdf files.

Step 2:

Cut the plans by a CNC milling machine.

I used Rockler CNC shark pro
(http://www.rockler.com/product.cfm?page=19666)
with BOSCH PMR 500
(http://www.bosch.co.jp/jp/pt/products/model.asp?id=PMR500).
with an 6mm endmill.

Step 3:

Assemble the parts.

You will need many hands when you assemble the seat part/the knee part with the bars
because you have to assemble all the bars at the same time
and wood naturally curves slightly so it will be very difficult for one person to do it.

Two questions, why aren't each of the sides made made from a sigle piece of plywood? Also, it seems to me, watching the video commercial for the Variér Furniture that leaving the center of the bottom part empty would allow the feet to touch the ground comfortably.

Thanks for your comment!

> why aren't each of the sides made made from a sigle piece of plywood?
That is due to the size of my machine(Rockler CNC Shark Pro).

Yes, I originally wanted to leave the part empty, but I didn't do that for its strength.
I want to revise it.

no tracing needed. Just apply printer tape to the wood and glue the plan on. You can work on it and pull the plan off pretty simple.

What are those circles in each corner? You used a CNC-robot - isn't that one able to cut that without such marks like a wood worker would be able to?
yuichirose (author)  tux_linux2 years ago
Miilling machines usually use an endmill to cut materials
so when you cut a rectangle, it will be rounded because of the roundness of an endmill and you cant get a correct rectangle.

So you need to make a circle in each corner.
Ah, ok, didn't know that. Well, could also be a design thingy. Anyway - well done.
That's awesome.

Nice! You could make a rocking chair with it as well. Very well done!

how are the rungs secured into the sides?
yuichirose (author)  Lorddrake2 years ago
The wood are slightly curves naturally so they are fixed enough.
There would be better way I guess though!
this could also be accomplished by the average jigsaw, correct?
yes, but you'd need to make templates to trace out patterns on the wood, and you'd also want a sandy and sand paper.
