Old tables are sometimes a bit low for everyday use. Here is a simple method to gain a few centimeters of comfort. Turned feet, square feet, curved... the system adapts to all styles and is also valid for the repair of a broken foot.
After mixing the components, you have about ten minutes to use the resin. Do it twice if you are not used to it.
The hardening of the resin at the bottom of the pot (allow a quarter of an hour) serves as a witness to decide when to begin the next steps.

The solution implemented presents little difficulty for an average do-it-yourselfer and requires only basic tools: saw, chisel, mallet, drill, drills or wood bits (Ø 12 and 14 mm), wood grater abrasive paper or sander, 12 mm diameter trunnion length, glue and two-component wood pulp.
The piece of wood to be added (the future extension) is wider than the foot section on which it will be grafted. This extension is secured to a pin acting as tenon. The latter is housed in a hole of greater diameter, drilled in the center of the table leg.
● The resulting play facilitates alignment of the extension before drowning the post in a two-component wood paste that forms a solid sheath. After curing, the extension is worked with the wood grater until you have the exact outline of the model.
For convenience, dismantling the feet is recommended. Separate the bedframe from the frame, then remove the pegs securing the sleepers and the feet. Choose a wood fall of thickness at least equal to the diameter of the table leg.
● Debit the four lengths you need. Each of them is summarily raised in a cylindrical form. A hole 12 mm and 40 mm deep is drilled in the center of each extension. A trunnion of equivalent diameter is glued in and then cut so that it exceeds 40 mm.
● The feet are drilled in turn, with an extensible wick (Ø 15 mm) on 40 mm deep. Present each foot / extension pair "blank" and, if necessary, correct the length of the tenons that must not abut against the bottom. Rotate each extension on its post to the best position in the foot alignment. Draw a marker to facilitate placement during bonding.
As solid as new
Prepare the two-component wood paste in a lost pot to obtain a homogeneous color resin (Arabois, € 13.40 the 230 g kit). Fill one foot hole to the third. With a stick, line the periphery and then the edge of the hole with resin. Also place a resin film on the contact surface of the extension around the post.
● Assemble extension and foot by aligning the previously drawn marks. Starting at the bottom, wrap a masking tape around the foot and back to the extender while continuing the swaddling, all tight.
● With a mallet, tap a blow to drive the tenon into its housing and flush the excess resin that will fill all the gaps at the junction.
● Store the feet vertically while the resin is hardening. Adjust with a wood grater, finish with sanding on a stationary belt sander.
Debit the extensions
The extensions are cut in a woodfall of the same essence as the feet. With wood, use an old wood chisel to separate the pieces in the direction of the wood grain.
Train and cut the extensions
Give a summary cylindrical shape to the extensions. Their section must remain greater than that of the table leg. Cut with a saw to obtain a flat and square contact surface.
Solidarize the drafts
Each blank is made integral by gluing a pin of Ø 12 mm pressed into a hole of the same diameter, drilled on 40 mm and centered as accurately as possible. Cut to 40 mm.
Coat the interior
Mix the two components of the wood pulp. Pour the resin obtained in the hole of the foot to a third of its height. With a stick, coat the inside to the edge of the opening.
Push the trunnion
When inserting the extension, align the positioning marks on the table leg and the added part. Push the pin into the resin bath.
Maintain alignment of the extension in the axis of the foot during "swaddling" of both parts with paint masking tape. The ribbon must come in recovery at each turn.
After sizing with a wood grater, use a stationary belt sander or sandpaper hand squeezed around the mandrel to reach the exact outline of the model.
The application of a wax shade masks the graft and makes it invisible (Liberon). The resin can be tinted at the time of mixing to attenuate the thin thread visible at the junction of the pieces.
