My monitor arm clamp keeps sliding off this cheap desk top
Three years ago I built a desk from a 1.5 inch hollow core door from Home Depot and it's been fine until last month when I added a second monitor arm. The clamp pressure is now bowing the thin top and the whole thing shifts if I lean on it, even after I added a plywood backing plate. Anyone else run into this with hollow doors, and is a solid butcher block insert worth the extra $60 or should I just rebuild the top now?
