Dimensional bad, when it's done very handsomely

The assembly is difficult. Unfortunately, the dimensional accuracy of the pre-drilled holes does not fit together with the sunken sockets. Much hammer and verknörte thread and a lot of time are necessary to the closet to get then in the end still look good. If the screws do not go in, I recommend 5er tapping screws. The eat pure and hold.
It is also difficult, the plastic buffer which are opposite the hinge and on which the disc rests rauszubekommen to move to the stop. Did they get bored and replaced by other buffer that I had at home.
