"an innovative engineer

who’s designed some

of the most successful

and iconoclastic racecars

in motor sports history"


Preston Lerner,

Popular Science, 2004


  I have devoted my life to designing vehicles that competed successfully in many
                different racing series, including cars, trucks, bikes, and motorcycles. I've enjoyed  
          inventing, prototyping, and patenting unique bicycles, transmissions and CV joints.


My passion to invent and design continues to race forward.



Below is a historical time line of my accomplishments.

Lincoln Zephyr chassis for $15.
