Abstract: A machine for bending thin wall electrical conduit having first and second spaced apart forming shoes, each having partial arcuate forming surfaces and a movable arcuate shaped third forming shoe mounted on the tabletop between the first and second forming shoes connected to an actuator for lineal movement forcing a section of tubing against the first and second forming surfaces with quick release retention wheels mounted on a flat plate in a cavity in the tabletop, the cavity having a load-supporting vertical edge for supporting the retention members under load and a pocket on the opposite side from the load supporting edge receiving an edge of the plate preventing it from lifting out of the cavity under load.
