Pinless mechanism

The pins that anchor the mechanism to the axles have disappeared on Eloy flutes. These pins that transmit movement from one part of the flute to the other weaken the mechanism and have been replaced by bridge parts that directly link the keys together. This stronger mechanism also eliminates binding keys and provides for a smooth action.

The long trill rod has been constructed in such way that no side play can occur. Controlled spring tension on one end of the rod ensures that play due to wear is automatically corrected.
