Mechanical Restoration

We bring back the precision and comfort of your bandoneon's action. Every part, restored with artisanal care.

What do we do when you leave your bandoneon with us for an action restoration?

Mechanical restoration is one of the most delicate and precise jobs we do. The action is the mechanical heart of the bandoneon, and its proper working is essential to the instrument's response.

At Bilbao Bandoneón, every part is recorded, cleaned and restored with special care, making sure it goes back to exactly its original place, now working like new.

The Restoration Process

A meticulous seven-step process that transforms your bandoneon's action

Opening and Disassembly

We open the bandoneon, setting aside the covers and bellows to focus on the action. We remove the hammers, detaching leathers, keys and pads. Throughout the process we carefully record where each part goes, so that after cleaning and restoration it returns to its original place.

Removing Components

We remove all the springs, tijeritas and stops that will be replaced with new ones. We clean every part: hammers, pads and table. This takes patience and precision to avoid damaging the original parts.

Crack Repair

If there are cracks, we repair and reinforce them: this fixes air leaks and improves the instrument's compression. Bandoneons often arrive with broken parts; in that case we replace them with new parts of the highest quality.

Fitting Leathers and Joints

We fit leathers to the base of the pads and glue the joints that connect the pads to the hammer. Every leather is carefully chosen to ensure the best possible seal.

Spring Calibration

We replace the springs and calibrate the weight of each one. This calibration is essential for an even, comfortable response when playing, preventing hand fatigue.

Keyboard Leveling

We fit the keyboard, leveling the keys so they sit evenly and harmoniously and feel pleasant to the touch. Good leveling noticeably improves the playing experience.
