Someone at the Creek mentioned Lee Valley as a good source of hinges and they do offer quite a variety. Barrel hinges and piano hinge with a positive stop both sound good and I will try them.
Most of my boxes will be 3/8" or 1/2" stock. Is there a butt hinge that has a leaf that is either 3/8" or 1/2" wide to facilitate installation via a simple dado vs more complicated mortise?
thanks
