I recently had someone ask me why not make my hinges square since I was planing the back side of them flat. Truth is I considered it, but could not get past the problem of the hinge jamming into the box as it rotated. If you look closely at the picture below, you can see how the corner of a square hinge rotates down into the imaginary box in the picture.

Anyone have any ideas?

Put the hinge on “sliding pins” so when you raise the lid, the hinge actually comes up off the box rim ….

Trying to think outside the box here :-)

Jerry, The square thought occurred to me as well but I couldn’t figure out a way to make it work. Mechanically, there has to be clearance for the hinge pieces to rotate. And that means you need a round hinge sitting in a round cove (like yours).

Possibly, if you were to route a channel between each of the pins on the box to allow the corners of the lid to pass unimpeded it may work. It would take a bit of trial and error to get it to work but based on your sketch up diagram I see no reason why you couldn’t get it to function.

Looking at it again, if you were using 3/4 in stock, if you used a 1/2 or 5/8 in core box bit to make the channels it may work.

Try a Z shaped pin , the lid should lift a bit that way and rotate clear the box .
I can’t draw it in sketch up but could do it on paper if you need it .

Ok jerry, I’m no artist ( and I dont so sketchup) Sooooo, I hope this is understandable.

The hinge parts that are normally glued to the box are glued to sliding pins. As you lift the lid, the hinge will actually raise up on the pins which come up out of the box. The pins have been inserted into the holes and allowed to slide up and down. My crude illustration shows the lid coming up clear of the box, but it should actually stay flush and “rotate” on the box edge and not actually come that high up. Is this clear as mud?

That’s a fine picture Joe, yes very clear. I was thinking of sliding horizonally, and of course that would not work, but this does. Furthermore, you have just created a very interesting hinge mechanism. I’m definitely going to have to try the “Joe Hinge”

Thanks!

Just when I thought there were no more ways to do a wooden hinge…..............Joe comes up with a unique one!

Do a top view of that drawing. I think there is a problem with clearance in the front of each knuckle

woodust, I think you are right. It will bind on the front edge of each segment.
