Thank You BB1! Yes, I have details...
This Pair of Hinges started in a Neighbor's yard

This Branch from a Pear Tree, looks alright in the picture,
but has large splits end to end on the other side...
It took a good deal of finagling to get even a small piece!
I got this...

These are cut and drilled from two directions... Holes first
Two different size holes for the cheek side to fit the hinge pin
(one to fit, the other loose-fit, so it turns freely, both, not completely through!)
I use wooden dowel for not only the Hinge Pin
but also for the "Pins" that attach the hinge to the box...
The top holes are undersized pilot holes for that...
The hinge profiles are cut next and a Hinge Pin is Tapped into the bottom half...

The hinges are set in place, and the bottom halves are glued on...

The holes are re-drilled to the correct size next... (Pre-drilling holes
is a lot less likely to split these small parts, than boring the whole hole at once!)

Dowels are glued  and tapped in next, one by one...

The bottom halves first, then the top halves, same way (glue first, dowels after...)
As I've said before, these take a lot of time and effort, but they do add a nice touch, 
are surprisingly strong and durable, and cost Nothing! :)
