Beginners of furniture masts are sometimes faced with a problem - where to buy a furniture shield. Factory samples are not always suitable for the conceived design, but the workpiece can be made independently.
1
For the manufacture of shields, it will take special equipment: planing machine, grinding machines (ribbon and flat octiculipal).
2
Board for work Choose one breed, without bitch, dried, with minimal charge. The best option is to buy logs and saw it on the workpiece of the required size. The corner of the cut is 90 degrees. Pine, oak, birch are suitable for making shields.
3
The dimensions of the rails must exceed the size of the finished product - necessarily the presence of an allowance for final refinement. Recommended proportions of widths and thicknesses - 3: 1, but you can make rails with proportions 1: 1. The width of the board should not exceed 15 cm, with drying in such blanks there are no high stresses.
4
In the furniture production, 20 mm thick shields are popular. Recommended billet - 25 mm. Excessively removed 2 times: 3 mm is removed before gluing, the remaining - during the finishing processing. To assemble the shield, a smooth rigid surface is necessary - a sheet of chipboard is suitable. On the perimeter, the planks are adjacent, prepare two wedges.
5
Place the boards on the chipboard and press each other. Inspect the tree structure on neighboring rails. The shield will be beautiful if all the billets of one color, and the lines in the adjacent samples are smoothly connected. Align the line, shifting the boards in length. It is more difficult to deal with oval lines and annual rings, so a lot of time goes to fit.
6
After drying the boards are always deformed, the direction of bends should be taken into account when selecting boards for shields. Most of all, wood is breeding towards annual rings, much less - to the core lines. For the manufacture of high-quality rail shield, place the annual rings in one direction or alternated with the opposite. In the first case, the surface of the shield will slightly get into the other - will be wavy.
7
If the shield is not power, the location of the annual rings does not play the role. On large shields, without rigidity (for example, for doors), it is necessary to alternate the directions of annual rings.
8
After placing the boards on the chipboard, their mutual layout label, which will allow you to quickly assemble the shield. The edges of the boards are treated with a fugomenon so that the surfaces of the rivers are located in the same plane. For tight fit of the boards, treat their ends. It is allowed to leave minor gaps if they disappear after pressing the hand. It is not recommended to eliminate gaps with clamps or wedges. After drying, such a shield will be with large internal stresses.
9
Finished boards are connected in various ways. Boards glue, if a large load will not be attached to the shield. Shields for furniture, which is operated with high humidity or in severe conditions, is made using brazening, knaps, plug-in rails.
10
Large-sized shields are obtained from smaller shields collected from 4-5 boards. It is easiest to make a glued panel. For gluing, buy glue for wood. Fold the boards into a stack and spread the ends glue. Position the boards to the chipboard on marking and press the clamps or wedges. After drying, the surface is treated on planing and grinding machines.
Wooden shields are very practical - they are not deformed, have a minor shrinkage, the structure of the tree is not damaged, so the invested means in the production of sawn timber pays off quickly.
