I guess I just dont understand how it is not tension on the pin when the scales flex apart. If you were to press fit with just enough force to hold the scales tight against the tang with the blade open, then close the razor. The scales will spread when the wider portion of the tang is encountered, and pull away from the tang.

these scales have very very little flex, but they are peened very tightly against the tang which flexes the scales open to some degree, also I installed/glued the wedge in first which created a wide spread at the pin, but the scales are shaped to help them bend in the right places to create a path for the tang. there are no bushings or washers. there is a small countersink in the scale pivot and were peened flush as Ignaz recently described.
