What is the turning circuit
Since I worked for a long time in the production of furniture, I've often faced with similar designs lockers.
In the manufacture of such products for the assembly of wood may be several solutions: dowel, spikes, conventional tongue and groove or dovetail connection.
When do these lockers of chipboard, it often employs a compound at the SCREW (evrovint). In this case, you need to use a little trick to screw the shelf to the central rack.
The trick is this: one of the shelves is attached to the B-pillar than one evrovint.
Then this shelf and the second shelf pivots fixed to two screws. After that, the first regiment put into place and secured with two screws to the side of the rack.
Ie, one shelf is fixed as usual on the four screws, and the other three.
Such a method of securing well-behaved shows for quick assembly of cabinets with lots of shelves and when small flange width (200-500 mm) this manner can collect, for example, filing cabinets or lockers like.
