CNC Milling
This week's mission is to make something big by using the ShopBot to CNC mill. We learned from designing the toolpaths, milling, post-processing and assembly.

Toolpaths Design
I always want a stool for outdoor painting. So I made this easy-to-assembly stool that can be laid flat in the car trunk and assembled on the go. It's in a palette shape cause I think it could also be a palette on the back at the same time..

SketchChair
I also found a software from KickStarter: SketchChair. It is a free, open-source software tool that allows anyone to easily design and build their own digitally fabricated furniture.

Fail #1
Even though I reserved 1 inch on each side, it still exceeded the milling area. The bit hit exactly on the nail in the wood and got broken.. Lesson learned: always reserve enough space.

Post-processing, Sanding

Fail #2
The hole turned out to be twice as big as the thickness of the material. So I have to use these small cut-out pieces to fill in the gap. I then used staple to fasten it.

Hammer to make it fasten more steadily.

CNC on my carefully selected patterned wood

To achieve this pattern:
1/4 straight end mill
1 rough cut + 2 finishing cuts with 90% stepover, rotated 90 degree
