Secondly, check whether the connection between the metal blade and the plate body is tight and firm. Whether there are defects such as looseness and holes.
Please check the remaining thickness of the metal part on the back of the blade. If it is too little, it means that this plate has been maintained many times. This is equivalent to the meter of a used car. Followed by the plate body, according to the material of the plate body, the attention points are also different. First of all, it is not recommended to buy second-hand wooden boards. Because you can't know what kind of suffering this board has gone through. Wood board is sensitive to curing and preservation because it is organic and full of holes. In the case of improper maintenance, the freezing and thawing cycle of internal water in winter will damage the holes in the plate like water pipes in winter. The humidity and dryness in summer will make the board as uneven as the soaked wooden floor, changing the layout curve painstakingly designed by the designer.
For ordinary resin plate, please check the following points. 1. Whether there are obvious visible injuries and potholes (slight scratches are almost certain, but they have little effect on skiing. By the way, waxing is not to make the plate smooth, but to make the plate rough and dry. On the contrary, the friction of rough surface on snow surface is smaller than that of smooth surface. ) 2. Does it creak when you bend? 3. Whether there is garbage and slippery thread scar in the screw hole of the lock. 4. If it is Barton's EST system, please check whether the setting is smooth and whether the lock feeling is unnatural when moving. By the way, please ask the boss for more locks.
