Changing shape of wood

Wood is easily formed as desired

Changing shape of the wood was common in all types of wood. The wood consists of millions of pillar composed of pores and several water that settles. When the tree was cut will free themselves from the pores of the wood. Nevertheless the water contained in the pore is not going straight out.

As the temperature increases the water that is in the wood will be forced out. Water will come out of the wood through the process of evaporation. If water is coming out of the woodwork then there is "space" empty in the wood and will create a bond among the pores become much closer. Thus the wood will shrink due to the loss of volume in the wood.

The water could have been back into the wood, although not as easy when it evaporates. The process of evaporation of the wood was heavily influenced as the drying process, the hardness of wood, as well as the position of wood when dried.

With advances in technology the forest easily results in the process. For the process of wood products should know the properties of the wood, so that best results will be obtained.
The most common thing the wood is hygroscopic which can absorbs and release water and also  be anisotropy, which has different properties in the longitudinal, tangential and radial direction.
The main disadvantages of wood can be attacked by pests and is flammable in the dry form.

The process of drying the wood very need to know to determine the final dimensions of the wood that will be used. With the drying of wood would be free of mold, making the wood more easily in bright paint or in varnish.

The prevention of the occurrence of cracks, ruptures and changes the shape of the wood  need to factored in wood drying process before being used.
After the drying process also remains a concern because the wood is also easily absorb water. After dried wood storage must be free of rain and heat and should not be merged with wood that is still wet.
Circulation in the wood storage space should be good and time the rainy season should be indoors. Plug the appliance in heating.

Anyway, for those of us who can not afford to buy four-part tables just for an original window frame, but we want it to look respectable, we have to - choose the cheapest tables. That said, I am pleased to add that smooth cutting boards are more than sufficient if you choose them well or if you are ready to "cope with the consequences". However, dealing with the consequences may not be as serious as it seems. To treat a board with a deformation along the edge (curve), you only have to cut off the offensive edges.

Take a straight edge and use the method I described in "Cutting a perfect line with a circular saw"  (This method does not work with larger woods, thicker than the maximum depth of the saw blade). Since you will have a board whose amount is less than the amount you have just cut, it is advisable to buy wood that is slightly wider than what is really necessary if there is a risk of deformation happening in the most cases. Cases and especially if it is possible that you are not using the tables immediately. Keep in mind that the longer you can sit and sow the wood, the longer the deformation will be.

The treatment of boards requires action against "brute force". Suppose the board is straight as long as I fold it "flat" and leave it that way, which just has to be done. All you have to do is find a shape that forces the wood to bend in the direction you want while making sure that the other end does not turn in the other direction. For example, suppose you want to build a very simple rectangular door frame, but its vertical planks look like screws. (Note that in real life there is only a certain amount of twist that you can do to get a piece of wood.) First place the 2 vertical boards on the horizontal top.

Now put the rather delicate frame on the wall. After the upper half is secured, it must now "lock" between the non-displace able wall amounts, except by applying a force with a hammer or the like. But the lower half of course hangs free like a rag doll and can be manipulated arbitrarily. Since the vertical boards were twisted and the upper ends were set at 90 degrees, the lower ends should show the full splendor of the curves.

Make your final position inside the wall bolts and lift a bolt through the bolts and into the frame. - You probably do not want to see any screws or nail heads on the front of your door frame. This is to secure the top end so that it does not change, so you can focus all your energies with confidence on the bottom end. Cut out a wooden plate that has the same width as the door frame. With a piece of plywood on each end to protect the frame surface, knock the plate against the side of the revolving frame. This will essentially crush the rotation.
