Abstract
A brake shoe assembly is formed by precision stamping a net shaped web blank having a series of tabs projecting outward therefrom and stamping a corresponding table member provided with tab receiving apertures and bending the table member into a semi-cylindrical segment. The web blank and the table are assembled causing the web tabs and table apertures to be interlocked securely locating the parts temporarily prior to the cooperating tabs and apertures being permanently joined together without any portion thereof extending substantially beyond the outer semi-cylindrical surface of the table.
