Triple-Piston Pneumatic Circular Saw [Restoration] (1x109)

Air date: Nov 10, 2022

This restoration is on a 1920s Model B12 "Safety Saw" pneumatic circular saw made by the Ingersoll-Rand Co.. The "Safety Saw" name was in reference to the patented design of the retractable blade guard, one of the first of its kind. This saw runs off of a triple-piston "Little David" motor that Ingersoll-Rand seemed to use in a number of their larger pneumatic tools.
