I designed a display case with frame & panel sides and back with a solid top and bottom. I built the frame & panels before realizing I don’t know how to connect the panel assemblies to the top and bottom and still allow for wood movement in the solid pieces. What is the best way?
thanks.

This requires a little room inside the cabinet. About 3/8" from the underside of the top will do.
I make 1" long 1/8" wide and 1/4" deep slots in my sides, whichever way that will be perpendicular to the grain of the solid top. These will be 3/8" from the top edge. Then I make small L-shaped tabs. The narrow end of the tabs is sized to fit into the slot, but have room to slide left and right. The flat part of the tab is 3/8" thick and has a hole for a screw through it (See photo). You slip these tabs into the slots, then screw through the tab into the top piece. The screws hold the top, but the tabs move in the slots if the wood expands or shrinks.
If you look in good woodworker supply catalogs, you can find Z-shaped metal clips made to serve this same purpose.

*Bob, I also use Dave's clip method. I used to make wooden clips but lately have used a lot of the small black metal Z's. While they are a bit crude compared to wood, I don't find them too objectionable since they don't show and I can quickly and safely cut the slots for them with my biscuit joiner. Be sure to position the slot so that the clip applies a little pressure when the screw is tightened.
