Abstract
A lap blank and holder assembly includes a lap blank having two spaced apart flat surfaces separated by a given thickness and formed from a material capable of compressing about a member inserted into it. The holder has a projection extending outwardly from a front face thereof and is inserted into the material making up the lap to secure it against rotational and shifting movement while being cut in a surfacing machine. This arrangement further allows the assembly to be placed as an assembly in a finishing machine for subsequent polishing of a cut lens surface in a polishing procedure.
