Subtraction Week 1: Router

To finish the assigned shape, firstly I need a pencil. (The pencil sharpener is much worse to use than knife)

I need to make sure where the center is.

Then I need to fix the wood.

And I need to grill some holes to fix the ruler.

When I tried the first time, I forgot to combine the ruler with the router, so I made it really awful.

Then I fixed them together and I got the shape I want.

When making the line, I drew two lines and tried making their distance equal the radius of the circle ruler. But when I fixed the ruler, I found it not exact, and it was hard for me to move the ruler and fix it again.

So the line I cut is disgusting… I hope I can┬ácontrol the screw better next time.
