I know the feeling of building something and then finding it broken . I needed a huge table to set veg transplants out on last year so i built one . In a hurry to get it done , i had plants that desperately needed space ; i threw one one together DIY WORLD in design . After it was done i filled it with several hundred seedlings and was very happy i had them spaced out with room for air circulation . The next morning i went out to water them and found them in a huge pile on the ground . The screws failed and the legs caved in .
