CNC for Custom Engines

Retired Electrical Engineer Terry Mayhugh of Round Rock, Texas used his Tormach PCNC 1100 to build a Jerry Howell 4 cylinder twin cam 4-stroke engine—a project two years and approximately 3000 hours in the making. Mayhugh’s other machining accomplishments include a Rudy Kouhopt radial engine and a Howell V-Twin 4-cycle gas engine.
