DescriptionThe Woodwork Lathe * Preparing a wooden blank for turning between centres * Craft & Design Product Design.jpg |
As part of the required course knowledge pupils need to be able to outline the process involved in taking a square wooden blank and preparing it for turning between centres. These pictures depict that process chronologically. Stage 1 * Preparation of wooden blank. Cut to size. Sand square. Mark across diagonals. Centre punch the centre point. Use spring dividers to mark circumference. Repeat on other end. Stage 2 * Plane off corners down to circumference line. This takes cross section from square to octagon. This reduces force on cutting toll in initial prep of blank. Mount between fork [driven] centre and dead [or live ] centre at tailstock end. Apply grease a dead centre end. apply force from tailstock end to force fork into material at driven end. Adjust toolstock height to suit. Check for clearance. Stage 3 * Roughout using scraper to diameter. Use combination of gouges and skew chisels to add beads and other decorative detailing as required. Ensure spindle speed is appropriate for material and cross section under consideration. Obey all safety instructions. |
