If I knew the correct name of the hinge assembly, I might be able to find it. I picked up an old cabinet years ago with the idea that I was going to install a light and sheet of glass and make a light table. Now, instead, I'd like to put an old SM head into it, but need to replace the front flap which supports the machine when it is in the raised position. I know that people collect this type hardware from the most pitiful of cabinets. I have a friend who will cut and route the new part, but we need the invisible hinge assembly. Anyone know what I'm talking about?
