The final assembly is what kind of people with a lot of patience and a sharp drill. Screw thread with rattan WRAPPED requires only times the exposure !! and drill through the thread, where the screws should fit, but only if one the jeweilgen ca 1 cm wide displacement of the opposite thread has somehow overcome with a spin, the "around the corner" pierced ... Cave final weight: nix for heavy people (no, I'm very thin) max 50 kg per side, otherwise break the screws !!
