ATM Secondary holder design (thanks!)

[Tom.Stock@gsbsc.gensig.com]

     Thanks to everyone who replied regarding a good secondary holder and 
     spider design! 
     
     I ended up going with a pull system where the secondary holder is 
     pulled against an acorn nut by three screws.  It seems more solid, and 
     more like the commercial designs common right now.  Once painted flat 
     black, it looks great.
     
     I used it last night along with the spider I built using the steel 
     ribbons and am very pleased.  It took me about 30 seconds to adjust, 
     and it's rock solid.
     
     If anyone wants the details on my contruction methods just e-mail me.
     
     Next I will probably attempt Richard's idea that was posted earlier.
