Abstract
A side rail for installation in a shredder and method of fabrication in which the side rail has fingers that are partially embedded in a base. The fingers are made from steel and the base is made from cast aluminum. The fingers have a dovetail shape at an outer end thereof that is immersed in molten aluminum in a mold. When the aluminum is allowed to harden the fingers are embedded in the base. The side rails are much lighter weight than previous side rails, and are still sufficiently strong to be used in a mobile shredder.
