I know how the pumpenhorn valves work - and the McCracken is a completely different concept.
I do find it odd how I've heard absolutely nothing bad about this configuration from those who have played it, and heavy skepticism from those who haven't even seen it. -William -----Original Message----- From: Hans Pizka <[email protected]> To: The Horn List <[email protected]> Sent: Sat, Jul 10, 2010 10:02 am Subject: Re: [Hornlist] McCracken 8 Valve Single Bb 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). _______________________________________________ post: [email protected] unsubscribe or set options at https://pegasus.memphis.edu/cgi-bin/mailman/options/horn/archive%40jab.org
