HUTCHINS 2000 Straightline Sander

Features ^The only 2-Cylinder, common piston straightline with vertically-engaged, twin-drive gears. ^Lack of rolling gears common to all other straightlines eliminates humping and jumping at the end of each reciprocal stroke. ^Two in-line cylinders, micro-honed to eliminate cylinder-wall drag, power an oversized high-alloy piston. ^Double rack and pinion gear assemblies give twice-normal gear contact for maximum balance and thrust.
