For matching elevator halves, the CRC throw meter can be very valuable, though proper set up requires two of them. Set it up with the elevator neutral and a CRC meter on each half. Line up the scale so the needle is reading 'zero'. Then carefully swap the meters. If the halves are properly set up, the needles should still be at zero... if not, you have some work to do. This is not a new idea I know... but it's definitely an economical way to set up the halves and can be used through the full range of deflection. I have a Budd meter and like that too, and I also use a couple of sticks... but this works pretty well too.

The Hanger 9 meter is almost useless. It fell off my plane onto the table about 4 inches away and it stopped working... Got it working again but it is definitely less than accurate.
