Wood glue my dude.

My old dining table, which has been moved like 8 times, used to be a grandparent's, and was one of those pull-apart styles with leaves to make it l o n g e r, was super wobbly. Creaking and swaying all over the place.

I took the legs off and apart, and placed a good dab of glue in every single joint and screw hole.

It's gonna be a bitch to disassemble when I move again, but that whole table is SOLID now. I wouldn't have trusted sliding it across the floor before, now I can reasonably(?) stand on it if I need to dust this one weird window that's kinda high in my dining room.
