The wooden chair has set of parts which connect glue joints. Seams can disperse over time. The problem is that when drying the tree will contract. As a result, connections are loosened or absolutely disperse. Old glue can lose the properties that will also lead to breakage of chair.
Instruction
1. It is the simplest to repair chairs which have the legs implanted directly into the seat consisting of one thick board. The shaking leg needs to be pulled out. After that it is necessary to scrape out old glue. Then apply fresh glue on leg. The leg is ready. It was necessary only to implant well it back into seat.
2. It is much more difficult to repair chairs with side bar under seat. It is also heavy to repair chairs which have crossbeams between legs. Such designs have many finger joints on glue. For this reason it is necessary to sort chair extremely carefully. If only one seam has dispersed, then it is necessary to make thin opening in this place. Through it by means of the disposable syringe it is necessary to inject glue. The damaged site will be made.
3. Further it is necessary to understand as it is correct to glue legs. Old chairs which are executed from whole tree at the end of the past - the beginning of our century have normal connections of front legs with seat. They are inserted by thorn into frame under seat. Such design quickly is loosened and breaks. Even if you have eliminated similar defect, then in several years it is necessary to be engaged in repair once again. Any chair is exposed to loading from above. It is constantly moved, inclined, rearranged why there is shaking of glue joints. In this design the leg is literally the lever which can easily disconnect glue joint. That the design became steady again, it is necessary to take out the unsteady leg from framework, and then to paste anew.
4. By means of knife or chisel remove old glue which is on the top end of leg. Do it accurately not to scratch tree. Problems with chairs can arise because legs of the different size at them. Surely pay attention to it.
