The curved cornetts are completely handcrafted, in the historical manner, from a piece of wood cut in half, gouged out, finished to the most exacting standards and then glued back together with modern adhesives. A covered brass ferrule serves to strengthen the mouthpiece end of the instrument. An especially penetrating oil is used to preserve the bore's fine finish as well as the instrument’ pitch and tone. The cornetts are covered with a high quality leather. Historic decorative stamping, which enhances the beauty of the instrument, is also available. Although traditional construction methods are more difficult and time-consuming, cornetts made in this manner are actually stronger than resin and more stable than one-piece, steam-curved instruments.

   Straight cornetts, which have separate mouthpieces, and mute cornetts, whose mouthpieces are built right into the instrument, are individually turned on the lathe. They receive the same meticulous attention as the curved instruments, and have an easily maintained oil finish.  Maple instruments are stained to enhance the beauty of the wood. 

    A variety of select, well-seasoned hardwoods are used, normally rock maple and black cherry. German plum and Central American boxwood, especially fine woods, are recommended for solo instruments. The curved and straight cornetts are provided with an "acorn" mouthpiece made from horn. Trumpet players doubling on cornett may request a cushioned-rim mouthpiece made from acrylic material.

    Because each instrument is made to order, special requirements can be accommodated.
