    Stan Ellerbeck purchased this 1869 Gibbs and Sterrett steam engine frame from a collector in Bradford, PA, where it worked on a local oil field. The engine was converted to gas in the late 1800s but the cylinder and other pieces from that conversion are long gone.

    Stan came up with the idea for his crosshead assembly after visiting Coolspring Power Museum in Coolspring, PA, and looking closely at the Gibbs and Sterrett engines on display.

    Stan needed to make a cylinder adaptor mount for the intake valve assembly. In this photo, Stan is boring a hole in the intake valve mount casting to the correct diameter of the intake valve assembly.
