    Wow, that's a great idea, Bart!
    Saves the trouble of gluing/wedging in cross-bars  or disks for locating 
axles, and it's a on-size-fits-all approach! Also easy to  adjust the coil to 
spin with minimal runout, which is certainly helpful for  winding and coating 
(and keeps the darn thing from bouncing itself off the table  at high speed!)
    I'm guessing you use waxpaper between the coil form  ends and the insides 
of the disks, to keep from gluing everything together when  coating?
    Got a link to pics of your setup?
