Right, that was a lead. I guess I was trying to provoke a response as to what particularly Jim was measuring - e.g. net bearing only, or was he trying to get something meaningful in terms of isolating front bearing and back bearing.

In infinite detail, if you please. > Ron N Not for measuring net bearing. But I guess I'd like an idea what the components are. The plane of the bridge cap, and where bearing goes front and back of that seems relevant. Am I in left field? William R.
