ABSTRACT:
The method involves forming an impeller with a slightly out-of-round hole in the center, and an impeller shaft with a complementary out-of-round peripheral surface, slidably engaging the impeller and shaft together, and then rotationally torquing either the impeller or shaft (relative to the other) to effect a binding lock-up of the two.
