Abstract
A method of using a masonry block mold includes the steps of loading the mold with block fill through the top of a cavity formed in the mold, drawing excess block fill from the top of the cavity, compressing the block fill within the mold with a compression head moving into the cavity from top to bottom of the cavity. The mold includes opposing sidewalls which each have at least one step formed on their respective top edge to retain additional block fill proximate thereto and assist in the formation of a flange or other structural feature on the formed masonry block.
