Thanks for the reply. I had seen those in one of the table build threads, but there was no news on whether they have play or not due to the double hinge.Chris Chamberlain used these exact Lee Valley hinges in his table that he built. I had bought a bunch for myself and was worried exactly like you were about them having excess movement. I asked him to test them out and see if there was any movement. His response was while opening them there is a bit, but once open, they are very solid.
Have you tried them, or do you know if they have excess play due to the design?
