Motor Mount 1.2

The initial design, based upon the measurements described in the previous blog entry (dated 2/14/2013, Part 1), was constructed using 3/16 inch plywood, 1" thick wood blocks, and nuts, washers, and bolts.  The final finished product would be fabricated using plate steel and a good welder. 

The concept is to have a metal arch that rests directly on both BMW motor mounts.  By using three nuts, four washers, and a fully threaded bolt, it was possible to rigidly hold the two wooden arches parallel to each other during trial assembly and fitting.  The final design would include a metal band bent with a radius of about 5.725 inches (11.45 inches is the outer diameter of the Warp 11).  The base of each arch would be welded to the curved band.   Strategically drilled bolt holes in the curved base band would allow for the insertion of bolts directly into the motor housing.  These bolts would help prevent torque induced rotation within the motor mount while under full load.

This design requires that the arches be cut from steel plate, a curved base plate formed, and final welding all three pieces together.  The final height required to provide adequate strength of the arch (and the depth of the arch below the motor) has not yet been determined.  If the top of the arch were made flat, then the surface could be used as a mounting point for other components.  This design is simpler, but less universal, when compared to attempting to incorporate a modified BMW style left side motor mount as was previously described.
