I am making a shadow box display for a retiring military service member.

I ve been making a few valet trays to give away as gifts, and using splined miter joints (the ones that go across the joint for strength and decoration). The stock is 1/2” thick, and I m amazed at how strong the joints are, even before putting in the splines. I haven t gone so far as to break one on purpose, but I m confident they would be plenty strong on their own, particularly with a bottom glued in to prevent any sort of racking. Maybe if someone stacked some bricks in there and tried to pick it up by just grabbing one side it might crack — no, it d definitely crack…lol. Maybe I should include a warning not to do that :)

Edit: I m not saying don t use splines or biscuits, just that if the OP doesn t want to mess with them, it shouldn t be a problem for a small box with thick walls like that.

I’m not sure why you’re telling me all that. I gave the OP my opinion. Maybe my bad but when he said he didn’t want splines I thought he might be objecting to seeing the ends of splines. So I suggested blind splines. A well fitting spline will go a long way it aliening the joint and holding in place during the clamping process.

Edit to add. If he’s thinking of the doweling I think the spline would be better and easier. But that’s just me.
