The composition of the alloy for each pipe is based on its use, melted and then poured on a cloth or sand covered table.  Exactly as the practice undertaken hundreds of years ago, a container with liquid metal passes over the table, leaving behind a sheet of molten metal.  In this way the Pradella Workshop has recaptured the technique used by the renaissance masters. 

The metal sheet is planed by hand, and then cut to the dimensions of the register desired.

Then the sheets are rolled into pipes, one-by-one, soldered and finally all of the pipe’s parts are assembled.

This kind of casting and the pipe fabrication are high precision operations, and there are few in Europe that have attempted to adopt them.

Every type of reed wind case is built in the workshop.  Shallots, tuning springs and nuts are produced from different moulds, and the patterns are made by hand in the workshop.  Original designs by Serassi, the early organ making family from Bergamo, were studied, allowing Pradella to reproduce faithfully their reed stops.

 The workshop has the tooling available for the fabrication of reed cases of many schools.  The Schnitger style has been reproduced and moulds are available for the French style.
