Needles & Grooves

I have a 5x5 and a 4x4. 4x4 completely filled w/ records. 5x5 two-thirds - wouldn't hesitate to continue filling it. YOLO. Or, if you are crushed under your collapsed Kallax: YOL....ugghhhh

Yea I feel like when I anchor the shelf itself to the wall it’ll be fine. Worst comes to worst I see something hinky going on I’ll pull everything out and wood glue all the seams shut.
