Jobbing-moulder
A moulder whose superior attainments enable him to mould more than one class of castings. Such qualifications are acquired only by perseverance and industrious practice in many foundries, which not only differ in the class of castings produced generally, but differ also in their modes of producing the same casting. Moulders that are engaged exclusively on stove-plate, hollow-ware, snap-work, etc., are naturally unable to do this; hence are distinguished as stove-moulder, hollow-moulder, snap-moulder, etc. See TECHNICAL EDUCATION FOR THE MOULDER.
