Loktite or drip some candle wax on it.

Thanks Allison! I got the cover off and found the
adjustment side of the
terminal (left side looking at it from the front) and the focus is a screw
that goes into what looks like an HV transformer. I've adjusted it to be
razor sharp, now what do I use to "lock it down" ? What is that stuff that
looks like nail polish called?
