Paul & William, have you ever seen a Viennes valve - inside ? It is much simpler than a rotary valve. The difference is the fact, that the valves action is divided for inlet & outlet, which work as simultaneously activated pistons, which are assembled each other in the opposite way.
The McCracken horn in question (have never seen it) should have two rotary valves, acting simultaneously. So the description. No opposition to innovations except if excess weight is loaded to the instrument. No opposition against innovations, if adjustments can be made by the player easily, adjustment to make perfect rotor alignement. Furthermore, connecting two rotary valves needs linkage, which will act with changing the direction of movement for 90 degrees twice at least. This is not the case with the Viennese valve (double piston). ################################################################################ Am 10.07.2010 um 15:38 schrieb LOTP: > > King 1155 (modified Sansone wrap 5-valve Bb single--Geyer's > modification). > Players even in their 40s and 50s simply have had NO experience with > these > and other non-standard designs.
