Load Pin Problems

After spending the morning running a few tests, I have found an issue with some of the load pins. It seems that if the metatarsus cheeks that support the load pins are not precisely aligned with each other the misalignment pre tensions the load pin giving a false reading. Having taken one apart and talked to Josh it seems we both came to the same conclusion that we should have fitted spherical bearings to the metatarsus cheeks as well as the tibia bearings already fitted, this would allow for any misalignment in either assembly. Its a bit of a set back but I'm going to have to take the ankles apart and get the inside faces of the cheeks bored out to take a spherical bearing.. dull!
