I shared this procedure I used with Chris Feickert, Michael Fremer, and those attending the event about 5 years ago during one of Michael's seminars at RMAF.
Halcro's comment is correct.
The Feickert alignment tool can be used in this manner with the bearing cap removed. The pin on the Feickert tool will position itself center of the bearing cap prior to locking down the threaded pin lock on the tool. Once the pin is centered and locked, the threaded lock for the measuring bar can be tightened. While doing this the platter should remain locked down. Overhang can then be verified with the platter locked down and the bearing cap replaced.
