There have been many mounts which have benefited from four small pads of teflon in between the edge of the altitude bearing and the side board. Also reinforcing the sideboards and front board to the base board with shelf brackets reduces flexure.

Interesting Roger, thanks for the tips. The teflon idea is interesting.. As is the epoxy.
