We're cutting high flanges using the special shoes, carbide inserts and wooden block. Using the specified brake cylinder pressure of about 10 lbs, the piston seems to flex in and out as the loco moves down the track. We are winding up with a legal flange at a given spot on the wheel, but maybe 70 degrees or so around the wheel, the flange is still high. Anybody have an idea what we're doing wrong? One suggestion was we should be using TWO wood block rather than one, but the manufacturer says only one, and they are not familiar with the problem. We don't want to cut too far on the now-legal part in order to bring the high part down, but it probably can't be considered legal until it's all within spec.
Any suggestions? Thanks!
