Ken, I was talking about positioning the straight edge like you describe
but spanning both flanges on both wheels. Obviously one would need a long
straightedge to accomplish what I am referring to. USUALLY, only the
forward bogie arm is bent, and most often it is bent towards the frame with
tire wear evident on the outside of the tire. When the straightedge is
placed across one bent like my example, the flange will only contact the
side of the flange towards the rear of the coach while daylight will appear
between the straightedge and front of the flange. I hope my description is
not too confusing. Picture the coach on stands with tires and wheels
removed, with the bogie arms parallel with the floor. The straightedge
narrow edge is held against the mounting flanges on both bogies at the same
time. Side to side distance across the coach is supposed to be the same on
the front and rear bogies. SO, if one holds the straightedge tightly
against the rear bogie flange and against the front flange at the same
time, if in fact they are parallel, the straightedge should make uniform
contact on both flanges. Clear as mud, right?
Hope this helps rather than confuses you.
