Calibration Process



and remove the marks that the sawing process leaves on the pieces.



and leave the pieces at the desired measurements.



almost ready to varnish.


1.  It allows you to reduce calibration costs.

2.  You don't need an industrial sanding machine in your workshop.

3.  You save a lot of time and effort in sanding and calibrating the parts manually.

Final calibration is done with a machine that has two sanding rollers with 80 and 100 grit sandpaper.

The first roller roughs the surface, while the other roller helps to remove the first roller marks and to leave the surface completely uniform. It is in this process that one often discovers the true quality of some woods, whose beauty was hidden under that rough surface just got out from the sawing machine.

Obviously, after our calibration, the luthier or craftsman can adjust the piece to achieve the measure that he prefers, since they are left with enough margin to do so. In fact, this happen in most cases, from the guitar maker who finishes adjusting the piece with a brush and a cabinetmaker's blade until it is completely to his liking - there is no finish similar to that obtained by a knife in expert hands - or the electric guitar builder who, once the top has been calibrated, uses a milling machine to give it relief or to mill the cavities of the electronics.

In Maderas Barber we have our own list of final measures for the different pieces: necks, fingerboards, tops, etc. However, you only have to tell us if you want the piece to be calibrated to another size and we will do it without additional cost.

You can add the calibration service directly on the products that have this option available.
