For new instruments, a vinyl adhesive is used; for restorations, an animal-based glue is used. All surface finishing is done by hand planing.

 

Depending on the function of the part, it is left unfinished or treated with a natural product, beeswax or shellac.

 

A stock of hardwoods - walnut, oak, chestnut, cherry and fir – is stored outside the workshop.  Other prestigious woods, such as ebony, boxwood, olive and rosewood are also used for some particular components: keyboards or decorative inlays.

 

The use of modern manufactured materials, such as plywood, chipboard, veneers, etc. has been rejected absolutely.  Manual operations require the use of high quality hardwoods exclusively.  These must be carefully selected and then carefully cut to match their functional requirements

Keyboards consist of grained fir levers, covered with bone or boxwood, with carved key faces for the diatonic keys and ebony or walnut for the chromatic keys.
 

The bellows, made of fir or oak with alum tanned lambskin gaskets, supply air to all the organ, maintaining a single pressure and constant wind.

 

     

 

The wind chests, the heart of the instrument, are made entirely of oak, with the exception of the pallets, which are fir, using only the best slabs, rigorously selected, to guarantee long life and efficiency over time.
