MAKING A RECORDER

The beginning

After 15 to 20 years seasoning, sometimes even more, the boxwood logs are first split to follow the direction of the wood fibres.

Other woods with larger sections are sawn into squares.

Roughing down the pieces of wood

Spoon drills are used for this operation which is carried out on the lathe For better centering,the piece of wood is made to turn instead of the tool.

Each reamer is made to measure for one specific part of the bore, to which it gives its final shape and measurements.
