Porsche 914/6 GT5R
A friend asked me to help out with his Porsche race car so I did some chassis TIG welding, body work and custom air ducting. The air ducting was made by creating a foam core and molding the fiberglass around it. The ducting actually worked too well- it flowed so much air through the oil cooler that it had to be partially blocked off in order to get the engine oil up to temp. I also worked up an aero package for the car with a rear wing, air dam and splitter.
Mazda CSR sports racer
This was a former Ralt R5 that was turned into a CSR sports racer. My friend asked if I could modify the existing bodywork to fit a new larger wheel/tire setup so I made quick patterns and snap molds so I could mold carbon fiber wheel arch extensions and graft them onto the existing bodywork.

Compressed air rockets

An enormous necklace casting I did for the amazing Missmonster. She sent me a fantastic sculpted wax piece and I cast it in Sterling Silver for her.
