Flat pack / interlocking design question Answered
I'm trying to make a flat pack interlocking chair but cannot figure out how to get the bottom pieces from falling out when right side up. If I want the chair to have a uniform square shape, I don't think I can make the locking cuts at any angle.....so, the bottom keeps falling down.
Below are two examples of interlocking that confuse me. The first is a link to the table upside down. The second is a link to the table right side up.....Can someone please explain how the long pieces which are in the "under" position of the lock do not fall out when turned right side up?
