Thought i'd give here a try for some help. Have one of these and trying to remove disks as they're slightly wobbly (no fault of mine ) can't find a way unless i start taking gearing to pieces under the disks. Btw its not the same design as L2. Also do the disks have to be perfectly in balance?mine aren't to bad really. Before i start digging in and making matters worse for myself! Tia
