Guide
1
Take planed plank width of 140 mm - is the height of a standard cinder block .The board must be carefully treated to the surface was smooth.Length of the board's your choice, it must be a multiple of 140 mm, - the width of the block, the shape may include three, four or more blocks.Do not make more than 2 meters in length - to work with the long form of uncomfortable.

From one board cut with a saw the cross, their length should be 300 mm.Connect the extreme longitudinal cross with planks so as to obtain a rectangular frame.Be sure to observe angles, exposing the
board before they are assembled on a perfectly flat surface with the help of the polygon.

cutting sheet metal thickness of 3-4 mm plate size of 140 to 300 mm.In addition to metal and other suitable durable sheet material, such as PCB.The main thing is that it has a smooth surface was hard and resistant to moisture.
