Another one I learned the hard way and which resulted in this solution;
Removing (and attaching) spring washers to pushers often leads to the frustrating jump of them (im happy my ears are well, I used to locate them by following sound)
Nevertheless, I lost a few. Until I came up with this solution: place the case inside a plastic seal bag and pressure the spring washer through the plastic. The spring washer jumps but stays inside the bag..
