A very simple, quick and beautiful diy that anyone can do. Watch the instruction video to see how I built it using an old soviet table saw.
Step 1: Foundation
To hang my shelf, I used two metal 90degree angles. This way I got and durable and solid foundation and saved some time since I didn't need to build a wooden frame. Make sure you don't forget to measure the interior distance of the shelf to space the metal brackets properly. And use a level, don't trust your eye!
Step 2: Attach the Shelf
Slide your shelf onto the metal brackets and you're all done. There is no need to put any more screws or nails into the wall because the shelf hangs right as is. And of course it's durable, but not durable enough to hang on!
