What kind of hinge do you think this chair would use? Answered

I know enough about furnature,and it look to me that that the is a 1/2in wooden dowel running through both halfs of the chair to forum a axle. I would make this chair out of some forum of hardwood because I do not think that a 1/2 in pine dowel would last under much pressure.

If you look closely, there doesn't need to be a hinge. A bar just behind where the back meets the leg will do the same thing-you can just see the bar between the first two slats of the back. Still folds up and you don't have to try to drill all those matching holes : )

I imagine that it just has a rod that goes all the way through where the back and seat intersect.
