Bill, Only has one occasion where the Vogel jacks saved the day and 
it was in believe it or not a Zuckermann kit, The Ed Kottick octave 
virginal which is based on that french monstrosity in the Berlin 
collection. The bass octave and tenor octave jacks travel between the 
strings and the soundboard. As the strings run transversely accross the 
vertical sound boards front and back all the jacks running in tenor and 
bass octaves must be mitered to place the tongue from bottom to top of 
jack. The vogels are parallel and miter very nicely except for an 
ocassional long wire spring. I used the standard I beam jack in the 
upper soundboard where tapered jacks seemed in order. Ed told me only 
six of these beasts were ever made after his prototypes. I had a lot of 
other rescue work that was needed for the thing to work. It has 4 jack 
rails. I have to admit that when folks pin the strings too close to the 
jacks, you can still get them to repeat.  JP
