2013 Personal Best Second Place Winner in Unusual and Unique, LT15 owner Bob Harbrige
Inspired by a steam engine design in his grandfather’s mechanic’s book from 1900, Bob Harbrige decided to build a fully-functioning, wooden air engine. Using his Wood-Mizer LT15 sawmill, Bob sawed 30 board feet of hickory, white oak and black cherry for the 39” x 20” x 19” machine. “The engine has been used to run a small generator powering LED lights,” said Bob. “It has a three inch bore and a six inch stroke and works on approximately four psi of air pressure created by a vacuum.” The intricate work that went into the four month project makes plenty of use out of quarter sawn materials from Bob’s Wood-Mizer sawmill.
