I'm seriously looking into materials to build a table like the one pictured below, I understand the overall construction of the table pieces and I have an idea on how I'm going to make some pretty sturdy legs. The thing I cannot find online are the same style of hinges used. I believe they are called Pivot hinges or Knife hinges. But what I am finding is way too small, too thick, and WAY to overpriced. Just wondering if anyone here has an idea? I was considering trying to make them using a Rivet as the hinge point but I would assume I could find something like this online. The last two pics are for a reference of the hinges.

Not sure if their knife hinges will work for your application or not.

Look for 'piano hinges' in your choice of color and material.

Google Rocklers.
