Description
This unit of competency defines the skills and knowledge required to manufacture patterns for cast marine propellers. Marine propellers may be built up using predetermined thicknessed timber, either over a mandrel or a layout. Patterns may be set up on a joint board or plated for ease of moulding.It covers timber, epoxy and composite constructions incorporating appropriate pattern making principles and techniques, Patterns may be set up on a joint board or plated for ease of moulding.Where the assembly of plated patterns is required, unit MEM04012 Assemble plated patterns should also be selected.Where the selection and use of precision measurement is required, unit MEM12003 Perform precision mechanical measurement should also be selected.No licensing, legislative or certification requirements apply to this unit at the time of publication.Band: AUnit Weight: 2
