Jack Rossman, a Seven Mountains resident, retired from his job as a machinist in 1989. That's when he began constructing his models of early 20th century engines. The devices, known as "hit and miss stationary gas engines," were used prevalently in the early 1900s. Farmers found them useful for a variety of tasks.

Rossman works on about 10 engines at a time and he says it takes him a year to complete their delicate construction. He then attends shows to sell his work. The only models he won't sell are the first prototype engines he built when he first took up the craft.
