MAKE SOMETHING BIG

 

SCISSOR TABLE

 

Specifications :

-3/4 sheet total material

-25 minutes total machine time

-40$ total material cost

-1 hour assembly time

I began making a corrugated cardboard model to test construction sequence and rigidity.

 

 

Underside view of Scissoring notch connection. Despite being diagonal to top surface, the legs are all perpendicular to one another.

 

Table top behaves like a compression ring, preventing the legs from splaying, increasing rigidity significantly.

 

First CNC'd module.

 

First full prototype

 

I CAN STAND ON IT!!!

SOME NOTES ON NOTCHING / ASSEMBLY

Variations in notching system .

Right Example produces less rigid connections that easily slip out, although easy to put together

Left Example produces more rigid connections that wont slip, extremely difficult to assemble. Must bend material to align.

The final piece must be rotated into position. It's rotation causes the other 3 legs to bend out of plane.

Best strategy is to loosely connect all four notchs per module. Then two people gently flex the 4 legs back and fourth until they fall into equilibrium. Once in place the module is sturdy.

Same issue on the actual table. The assembly requires two people to work in unison to complete.

Moral of the story, dont brute force it, work in concert with another and things fall into place.
