In Maderas Barber we also offer a bending service for those customers who don’t have their own bending machine or any other system that allows them to perform this delicate operation in the construction of a guitar.

1. CALIBRATION

Once the wood to be bent has been requested, the first step to do, prior to the bending itself, is the calibration.

This process leaves the sides at a final measurement of 2.5 mm and a completely smooth surface that will help in the bending process. This calibration process is included in the same price as the bending sides and doesn’t entail any additional charge. 

2. IMMERSION IN HOT WATER

Once the sides have been calibrated, they are immersed in hot water in a container that, through a thermostat, allows us to adjust the temperature to the optimum point required by the wood we are working with at that moment. There is a very wide range of densities and mechanical qualities among woods, which makes some of them better candidates than others for bending sides. If you have any doubts when choosing the wood you want us to bend, don’t hesitate to contact us, and our professionals will recommend you the best option taking into account your tastes, needs and budget.

3. BENDING SIDES

Once the submerged wood has reached a temperature that we consider ideal, it is placed in a side bending machine, the rings are covered on both sides with Teflon sheets that will help the wood to adapt to the mold with the least possible friction. This machine bends the sides by heat, the molds have internal resistances that heat them and we control the temperature with a thermostat; in the same way as the containers where we dip the sides.

We have two molds: classical guitar and cutaway. In the graph below you can see the approximate measurements of the sides in its final shape, once bent.   


4. PLACEMENT ON STENCIL

The sides remain in the bending machine for about 15 minutes until the machine automatically releases them. Once free, the sides are placed in a template with the shape of the mold and left to cool for 24 hours at room temperature to avoid breakage or deformation.

Please take this into consideration when placing an order: it always takes an extra day if some sides need to be bent.

Once the bending process is finished, the sides present some stains as a result of the same process, it is perfectly normal

Some oils naturally present in the wood, the bending water that evaporates unevenly, small sawdust residues, etc. A light sanding and the calibrated surface of the sides will appear again in all its splendor.

You can add the bending service directly on the sides that have this option available. We perform this service only on classical guitar sides and it is possible to choose the bending with the shape of the traditional classical guitar or cutaway.
