Wooden furniture backplane is the whole wood and finger connection what is the difference?
Use finger knife two short wood joints play jagged out on the machine, glue, two short pieces of wood can butt up, another head and teeth do not, then use the same way to the next block length, with the same length of the transverse plate together. Short wood, scrap, scrap, leftover material, which can be utilized, saving wood resources, of course, for some knotty species, to make clear the board, it can only by the finger joint way to make clear the plate out.
From the coefficient of deformation, the finger plate is easier to deform and crack than the straight plate.Now say solid wood furniture, back board for solid wood whole board problem,As long as the solid wood plate, whether you are a straight plate or finger board, thermal, moisture absorption, will cause mainly transverse expansion or contraction may, in check by nails, because the inner stress of the board to be hampered by the risk of cracking, deformation is very large, so not solid wood board to do the back board, the correct approach should be: knock frame, frame safely board, give you a knock on wood framed pictures look back;
The whole wood should be understood as straight plate whole plate inside it, because the back with a finger, here must first clear straight board is how to do it, after the trees cut down, according to the dimensions of sawn board specifications, such as 8 cm thickness * natural width *2.5 meters long, after drying it is good to do furniture, but not up to the back of the big area ah, how to do, the thickness of 8 cm cut, cut into about 1.5 of the thickness of 8 cm width of the blade, and then used the straight sliver width 8 cm thickness of 1.5 cm length of 2.5 meters to reach the plate, the standard plate area of 1.22*2.44 meters, the actual area is more than the thickness is, but after sanding and cutting irregular edges, thickness of 1 centimeters, has reached the area. It's a long straight strip with solid wood. It's called straight jigsaw.
