Site Considerations Weight Load Physical Environment Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Cleanup Mounting The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean. Although not required, we recommend that you mount your new machine to the floor. Because this is an optional step and floor materials may vary, floor mounting hardware is not included.
Assembly The G0733 and its components are very heavy. Get lifting help or use power lifting equipment such as a forklift to move heavy items. 4. If bolting the lathe to the floor, skip to Step 7. Otherwise, move the tailstock, tool rest assembly, and headstock to one end of the lathe bed (refer to OPERATIONS section, beginning on Page 19, for instructions for moving these components). 5.
Power Connection 7. Place the level on the lathe bed and make necessary adjustments so that the bed is level from side-to-side and front-to-back. —If you are using the machine feet, adjust the top and bottom hex nuts on each leg to level the bed; then tighten the hex nuts to secure these adjustments. —If you are bolting your lathe to the floor, use shims under the legs to level the bed; then tighten the mounting fasteners. 8.
Test Run Once the assembly is complete, test run your machine to make sure it runs properly and is ready for regular operation. The test run consists of verifying the following: 1) The motor powers up and runs correctly and 2) the STOP button safety feature works correctly. If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, then review Troubleshooting on Page 37.
Operations SECTION 4: OPERATIONS Operation Overview To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations. Damage to your eyes and lungs could result from using this machine without proper protective gear. Always wear a face shield and respirator when operating this machine.
7. Verifies the pulley ratio is set for the appropriate speed range for the operation, type of wood, and size of workpiece installed. Basic Controls 8. Verifies the spindle direction switch is in the "O" position and the spindle speed dial is turned all the way counterclockwise so the spindle does not start turning at high speed. Refer to Figure 17 and the list below to familiarize yourself with the lathe controls.
Stock Inspection & Requirements Some workpieces are not safe to turn or may require modification before they are safe to turn. Before turning a workpiece, inspect all workpieces for the following: • Workpiece Type: This machine is intended for turning natural wood products. Never attempt to turn any composite wood materials, plastics, metal, stone, or rubber workpieces; turning these materials can lead to machine damage or severe injury.
Tool Rest Adjusting Tailstock Adjusting Tool Rest The tailstock adjusts in the same manner as the headstock. The tool rest assembly on the Model G0733 has two adjustable components, to provide the safest and most stable position when operating the lathe. The tool rest base adjusts in the same manner as the headstock and tailstock. The tool rest pivots and may be adjusted vertically in the tool rest base. To position the tailstock along the length of the bed: 1.
Headstock Center Always operate the lathe with the tool rest assembly firmly locked in position. Otherwise, serious personal injury may occur by the tool being pulled from the operator's hands. 2. Make sure the mating surfaces of the center and spindle are free of debris and oily substances before inserting the center to ensure a good fit and reduce runout. 3. Insert the tapered end of the center into the spindle, and push it in with a quick, firm motion, as shown in Figure 22.
Tailstock Center Installing/Removing Tailstock Center 5. Make sure the center of the quill lock handle is aligned with the quill keyway to ensure that the tailstock center and quill will not freely rotate under load (see Figure 25). The included live center installs into the tailstock quill with an MT#2 tapered fit. Installing the Tailstock Center 1. On the tailstock, loosen the quill lock handle and rotate the handwheel until the quill extends out about 1", as shown in Figure 24.
Headstock Faceplate Installing Faceplate To install the faceplate: 1. DISCONNECT LATHE FROM POWER! 2. Insert the indexing pin into one of the indexing holes and rotate the spindle until the pin engages to prevent the spindle from turning while you tighten the faceplate, as shown in Figure 26. Changing Speed Ranges Changing Speed Ranges The Model G0733 has pulley belt configuration provided two speed ranges (see Figure 27).
Always choose the correct spindle speed for an operation. Using the wrong speed may lead to the workpiece being thrown at high speed, causing fatal or severe impact injuries. 2. Open the front belt access panel, as shown in Figure 29. 5. Reach into the belt access cavity and roll the belt onto the desired set of pulleys, as shown in Figure 31. Spindle A = High Range 330-3200 RPM B = Low Range 100-1200 RPM A B Motor Figure 31. Speed range belt positions. 6.
Spindle Turning Indexing Spindle Turning Indexing on a lathe is typically used for workpiece layout and other auxiliary operations that require equal distances around the workpiece circumference, such as clock faces or inlays. Spindle turning is the operation performed when a workpiece is mounted between the headstock and the tailstock, as shown in Figure 35.
2. Make a center mark by using a wood mallet and tapping the point of the spur center into the center of the workpiece on both ends. 3. Using a 1⁄4" drill bit, drill a 1⁄4" deep hole at the center mark on the end of the workpiece to be mounted on the headstock spur center. 4. To help embed the spur center into the workpiece, cut 1⁄8" deep saw kerfs in the headstock end of the workpiece along the diagonal lines marked in Step 1. 5.
Spindle Turning Tips: • When turning the lathe ON, stand away from the path of the spinning workpiece until the spindle reaches full speed and you can verify that the workpiece will not come loose. • Use the slowest speed when starting or stopping the lathe. Faceplate Turning Faceplate Turning Faceplate turning is when a workpiece is mounted to the faceplate, which is then mounted to the headstock spindle, as shown in Figure 39.
Mounting Workpiece to Backing Block 1. Make the backing block from a suitable size piece of scrap wood. Note: The faces of the backing block must be flat and parallel to each other, or the uneven surfaces will cause the workpiece to spin eccentricly, causing unnecessary vibration and runout. It is best to mount the backing block to the faceplate and turn the other surface flat prior to mounting. Figure 40. Typical attachment of faceplate to workpiece.
To outboard turn on the Model G0733: 1. Sanding/Finishing DISCONNECT LATHE FROM POWER! 2. Remove the tailstock and tool base from the machine by removing the hex nuts and clamp washers located underneath the assemblies, then lifting them from the lathe bed. After the turning operations are complete, the workpiece can be sanded and finished before removing it from the lathe, as shown in Figure 43. 3. Loosen the headstock, then move it all the way to the tail end of the lathe bed, as shown in Figure 42.
Selecting Turning Tools • Lathe tools come in a variety of shapes and sizes, and usually fall into five major categories. • Scrapers—Typically used where access for other tools is limited, such as hollowing operations. This is a flat, double-ground tool that comes in a variety of profiles (round nose, spear point, square nose, etc.) to match many different contours. Gouges—Mainly used for rough cutting, detail cutting, and cove profiles.
