Gluing solid shelves into dado

Hi Lumberjocks, quick question, is this a cross-grain glue up and if so, how would you handle it. I need the ears on the shelves to stay tight to the rails. Material is Cherry.

The parts look quiet narrow, so I wouldn't worry about expansion and contraction here. It looks to me like any movement will be matched by the adjoining piece, so I don't see any issue.

Just use spring clamps or quick clamps to hold the ears down, then add parallel clamps from underneath to close the joints.

Besides the fact that the pieces are narrow, all the wood movement is going in the same direction on all the pieces, so, no, it is not a cross-grain situation.

The issue you might have is keeping the dado joint tight, as this is all long-grain-to-end-grain joinery. Clamp it well-and maybe add a few fasteners. Will it have a back, or something to keep the sides from spreading?

I envision a low-stress use (spice jars?) so it's probably fine, but a couple fasteners would buy some insurance.

Thanks lumberjocks. It is a display shelf for small bottles of essential oil. About 14×12. I glued it up last night and clamped across the width. All the ears were tight. I tapped one of the down. Gouldnt figure any smart way to clamp the ears so i just left it. I used tight bond III and appears to be solid now.

I put a little natural Danish Oil on it. I am spraying satin laquer over that.
