The easiest to do is a sliding lid , I make my boxes with half lap joints doubles the glue area , and a half lap for the lid into a groove cut the grove off from one side , and the sides should line up .
Thank you, that is a good to remember.
I'm including three pictures of not that gerat box and three pictures of a good box.
First one is chinese cheap plywood, the box was in that state when new and I got it.....Whole inerior needs a rework.
Second one is Polish made and it is cheap but allready usefull.
Last one is pretty good really, good hardware, good plywood and interior is solid pine.
And rest of you: Stop barfing - it is just wood, splinters will not kill you.
