Furniture that has play is subject to breakage. It is important to remedy this, without the need to disassemble everything.
Make a false tenon
To change a broken post, cut a new one in wood similar to the wood of the piece of furniture, or otherwise, the medium.
The old tenon is removed and replaced, either by cutting a mortise, or by fixing the new tenon with ankles.
Create a mortise
Saw the old tenon flush. To equalize with lime.
Then cut a mortise in the room, using a chisel.
Cut a piece of wood, the size of which must be double that of the mortise, in medium.
Coat the mortise with vinyl glue and insert the new post.
Fix new tenon
Obtain three wooden pegs.
Drill three holes, the width of these ankles and half their length, in the wooden room.
Glue the dowels and place them in the holes.
Drill three identical holes on the false post.
Glue vinyl glue the other part of the dowels, and push on the false post.
In this case, the tenon is longer than in the other.
How to consolidate and stiffen a wooden chair
To eliminate easily the play between different elements of the chair, simply fill the gaps with blocking glue.
If this proves to be insufficient and it is necessary to disassemble the chair, give small shots of rubber mallet to separate the pieces from each other.
A spacer clamp allows to remove a bar without having to disassemble everything. With each pressure, the jaws deviate one centimeter.
Hold the bar securely on the workbench and sandpaper the mortise so that the remaining glue is removed.
Glue the bar post liberally with vinyl glue (or white glue).
There are quick-setting white glues.
Replace the bar, then remove the excess white glue with a sponge before it dries.
Keep the elements tight for a few moments.
Using a strap, firmly hold the pressure between the different parts of the chair.
Let dry overnight.
