Based on the blog Ben showed us during class, I planned to make a simple joinery like this:
So I drew two files:
And I picked the first one to cut.
The biggest mistake I made is cutting that middle line by CNC – it was too wide, more like a rectangle, but I just wanted to cut the square apart.
So I kept the heart shapes and cut the square again. It was exactly the same file, but the heart shape showed differently. And the pockets showed like contours.
Finally my joinery was like this. It almost fit, but it was awful and breaks very easily. I think it’s because of the shape, which should be narrow in the middle and wide at both ends, but the heart shape doesn’t meet the requirement.
It’s a terrible trying and I think I can do better next time.
