S. Blakely presented a paper, "Demonstration of a Full Scale Egyptian Pulley," at the 8th Experimental Archaeology Conference, Oxford University, UK, January 10, 2014.

Stephen Blakely was accepted into the membership of EXARC.  EXARC’s goal is “the investigation, contextualisation, presentation and interpretation of archaeological and experimental archaeological heritage.”

The full scale Pulley used in the successful 5,000 pound weight lift was on display in the Egyptian Gallery of the Spurlock Museum on the campus of the University of Illinois, summer of 2013.

The actual full scale test described in above article was completed successfully late on April 15, 2013 (test facilities courtesy of Marcal Rope & Rigging, Alton, Illinois).  The photo below shows the (first) full scale Egyptian Pulley (of limestone) used in the successful test, in lifting a ~5,000 weight up a 52 degree incline.  The Roller is 12 inches in diameter.  A video clip of this successful full scale pull is on YouTube at:
