Ok! This weekend I got a chance to really check out the scope for the source of the vibrations. What I found in the end was the Azimuth bearing bolt assembly was allowing to much play between the rocker box and the base board. It became apparent after I eliminated the Alt bearings as the source. I made a teflon bearing that slipped over the bolt between the plate and the base board flange. This acts as a spacer between them and makes for zero play in the bearing assembly. So now it is very solid like the 15" of the same design. Not sure why this 12.5" displayed this tendency when the 15" did not. But I guess it doesn't matter as long as there is a solution.
