Most sculptures aren't made to tolerances in excess of 1/1000th of an inch. Chris Bathgate's are.
Chris is a self-taught machinist sculptor who was born in 1980 in Baltimore Maryland. He still currently works and resides in Baltimore and has spent more than a decade learning how to build and use a variety of metal working tools and machinery. He has assembled an elaborate machine shop of repurposed and home made robotic and manual machine tools, along with a multitude of other equipment and inventions in the basement studio of his Baltimore home.
