Meredith Lamb, Bob or others that may have knowledge of Spregnether 5000 
Vertical Seis:
It has been my understanding that in setting up this machine it was 
imperative to have the unit mass indicator balanced between the upper and 
lower stop, which thus far for me has been illusive .  The mass indicator 
either slowly goes to the bottom or the top.  I have adjusted the spring 
wire and still I can not get it to remain balanced between the stops.  Does 
anyone have a copy of the manual who could provide a photocopy or email the 
setup instructions included or provide any tips or suggestions.
James Allen
