I’ve been working on making wooden hinges that can withstand abrupt forces, will last as long as the box frame and look good. I believe these hinges may accomplish this.
The 3×5 recipe boxes in the pictures are not finished because this project is about the hinges, and I wanted to show how they could look on a project.
The box on the right the hinges are padouk and 7/16” thick. They are two strips of identical thickness laminated together.
Here is the procedure I came up with to achieve this.
On my table saw I first re-sawed a flattened board down the middle to get the approximate thickness of the two halves. http://s850.photobucket.com/user/dpatterson31/media/Hinges/photo-25_zpsaf595eba.jpg.html?sort=3&o=9. http://s850.photobucket.com/user/dpatterson31/media/Hinges/photo-37_zps227fc84f.jpg.html?sort=3&o=8 .
I then trimmed the pieces to square. My next step was cutting a 1/8” flat bottom crosswise groove on each end of the flats, 1/4”+ in from the ends. The depth of this cut is important. I am going to fit a 1/8” square .014” brass tube in these slots so that it sits halfway in. Actually a tiny tiny fraction more than halfway. When done with this I then wipe it with acetone and glue up the two pieces with the tube in the slots. The square tubes make it much easier to clamp. http://s850.photobucket.com/user/dpatterson31/media/Hinges/photo-38_zps3bb58d19.jpg.html?sort=3&o=7 .http://s850.photobucket.com/user/dpatterson31/media/Hinges/photo-39_zps7b4daf04.jpg.html?sort=3&o=6 .http://s850.photobucket.com/user/dpatterson31/media/Hinges/photo-41_zpsc552d605.jpg.html?sort=3&o=10.
When dry I trim it up then proceed to trim back the end to 7/32” away from center of square tube. Also make sure it is parallel with hole by running a 3/32 brass rod in hole and checking . Then I run it through the router to get rounded ends. Then Cut finger joints with Incra I-Box.
