Use slower speeds for large workpieces (4" diameter and over); use the middle range speeds for medium sized workpieces (2" to 4" diameter); and use faster speeds for small sized workpieces (under 2" in diameter). • Make sure the turning tool is against the tool rest the ENTIRE time that the turning tool is in contact with the workpiece. • Learn the correct techniques for each tool you will use. If you are unsure, read books or magazines about lathe techniques and seek training from experienced users. • Turn the lathe OFF immediately if the workpiece vibrates excessively. Check to make sure the workpiece is centered and balanced. Remove the workpiece and trim excess waste off corners with a bandsaw or table saw to reduce vibration. Make sure the workpiece is securely attached in the setup. faceplate Turning Faceplate turning (figure 38) is when a workpiece is mounted to the faceplate, which is mounted to the headstock spindle. This type of turning is usually done with open-faced workpieces like bowls. If screws cannot be placed in the workpiece, then a backing block can be glued to the workpiece and attached to the faceplate with screws. figure 38. Typical faceplate turning operation. To mount your workpiece to the faceplate: 1. Find the center of your workpiece in the same manner as when spindle turning. 2. Cut off the corners of the workpiece. 3. Center the faceplate on the workpiece and attach it through the faceplate holes with non-tapered head wood screws as shown in figure 39. 4. Thread the faceplate onto the headstock spindle and tighten securely. 26- G0657/G0658 Benchtop Lathe NOTICE: Only use tap screws or wood screws with non-tapered heads (Figure 39) to attach the faceplate to the workpiece. Do NOT use drywall screws or screws with tapered heads because these can split the faceplate, or the screws may snap off during operation. GOOD BAD figure 39. Correct and incorrect screw types for mounting faceplate to workpiece. To mount your workpiece to a backing block: 1. Make the backing block (figure 40) from a piece of scrap wood that is flat on both sides. figure 40. Example of mounting faceplate to a backing block. 2. Locate and mark the center of both the workpiece and the backing block. 3. Drill a W diameter hole through the center of the backing block. 4. Glue the center of the backing block to the center of the workpiece (look through the drilled hole to line up centers), clamp the backing block to the workpiece, and wait for the glue to cure according to the manufacturer’s recommendation. Sanding/finishing After turning, the workpiece can be sanded, as shown in figure 41, and finished (in the same manner) before removing it from the lathe. figure 41. Typical sanding operation. Sandpaper I Acaution Wrapping the sandpaper completely around the workpiece will pull your hands into the moving workpiece and may cause injury. Never wrap sandpaper completely Workpiece around the workpiece! Whenever sanding or finishing, move the tool rest holder out of the way to increase personal safety and gain adequate working room.
