Breathe some life into your old Kimbrough servo saver
 

I noticed that my Kimbrough #124 servo saver was getting a little softer over time. I got a hint from somewhere (don't remember where, so I can't give credit) to pack it with RTV silicone. So I opened up the servo saver, filled the channel where the spring goes with RTV silicone, put the spring back in and popped it back together. It still gives a little bit--somewhere between a rigid servo arm and a new Kimbrough servo saver--just what I was looking for.
