This belt is 27.5" long. The high range belt is always used on pulleys A and C without using the tensioner. This belt is 33" long. 4. Close the side cover and secure it shut with the cap screw. The lathe is now ready to use at 150 RPM. ▲WARNING Use a low RPM when machining heavy eccentric workpieces; Objects thrown from a lathe can cause serious injury or death. ▲WARNING Use a minimum of three independent clamping devices when turning eccentric workpieces on the faceplate. Failure to provide adequate clamping will cause workpiece to eject. = 150 RPM 150/ 300 560 720 1200 2400 № BC2 BC3 AC1 AC2 AC3 Figure 30. Pulley combination (BC1) achieves 150 RPM at the spindle. -28- Model M1099 (Mfg Since 10/07) SHOP FOX, Power Feed Rate Use these steps to learn how to setup your lathe for a power feed operation. The example in Figure 32 shows lathe setup for a power feed rate of 0.012". Remember, the carriage direction is reversed when spindle rotation is reversed. To set and engage the power feed, do these steps: 1. DISCONNECT LATHE FROM POWER! 2. Turn the feed dials to the numeral and letter indicated by the chart in Figure 32. 3. Using the chart in Figure 32, gather the required change gears. 4. Open the side cover and use a 6mm hex wrench to loosen the lash adjuster (Figure 32) and swing the change gear assembly out of the way. 5. Remove the spindle E-clips and cap screw, lubricate, and swap out the change gears in the order shown on the chart in Figure 32. 6. Move the lash adjuster so the gear backlash is between 0.003" to 0.008", tighten the lash adjuster cap screw, and close the side cover. 7. Using a 5mm hex wrench, loosen the carriage lock (Figure 31), and use the half nut lever to engage and disengage the power feed when required. NOTICE Feed rate is based on spindle RPM. Pay close attention to the feed rate you have chosen and be ready to disengage the carriage. Failure to do this may cause the carriage to crash into the chuck. Figure 31. Carriage lock and feed control. Figure 32. Power feed setup. -29- OPERATIONS OPERATIONS SHOP FOX' Model M1099 (Mfg Since 10/07) Inch Threads Use these steps to learn how to setup your lathe for inch threading. The example in Figure 34 shows lathe setup for cutting 64 TPI (Teeth Per/Inch) thread. To setup for inch threading, do these steps: 1. DISCONNECT THE LATHE FROM POWER! 2. Turn the feed dials to the numeral and letter indicated by the chart in Figure 34. 3. Using the chart in Figure 34, gather the required change gears. 4. Open the side cover and use a 6mm hex wrench to loosen the lash adjuster (Figure 32) and swing the change gear assembly out of the way. 5. Remove the spindle E-clips and cap screw, lubricate, and swap out the change gears in the order shown on the chart in Figure 32. 6. Move the lash adjuster so the gear backlash is between 0.003" to 0.008", tighten the lash adjuster cap screw, and close the side cover. 7. Using a 5mm hex wrench, make sure the carriage lock is loose (Figure 31). NOTICE During threading keep your hand on the half-nut lever ready to disengage the half nut to avoid potential carriage/ chuck crash. Figure 33. Thread dial chart and thread dial. 8. The lathe is now setup for threading. Note: For faster threading and manual carriage return, based on which TPI being cut, refer to the Indicator Table in Figure 33 to know if you can use the thread dial scale to show when to re-enter the thread manually after disengaging the half nut lever. Figure 34. Inch threading setup. -30- Model M1099 (Mfg Since 10/07) SHOP FOX, Metric Threads Use these steps to learn how to setup your lathe for metric threading. The example in Figure 35 shows lathe setup for cutting a metric thread pitch of 0.45mm. To setup for metric threading, do these steps: 1. DISCONNECT THE LATHE FROM POWER! 2. Turn the feed dials to the numeral and letter indicated by the chart in Figure 35. Note: You may have to rock the chuck by hand slightly to get the gearbox gears to engage one another. 3. Using the chart in Figure 34, gather the required change gears. 4. Open the side cover and use a 6mm hex wrench to loosen the lash adjuster (Figure 32) and swing the change gear assembly out of the way. 5. Remove the spindle E-clips and cap screw, lubricate, and swap out the change gears in the order shown on the chart in Figure 32. Note: All change gears are stamped with the number of teeth they have. 6. Move the lash adjuster so the gear backlash is between 0.003" to 0.008", tighten the lash adjuster cap screw, and close the side cover. 7. Using a 5mm hex wrench, make sure the carriage lock is loose (Figure 31). 8. The lathe is now setup for threading. NOTICE During threading keep your hand on the half-nut lever ready to disengage the half nut to avoid potential carriage/ chuck crash. Note: Since this lathe has an inch lead screw, do not use the thread dial when cutting metric threads. Instead you must leave the half nut en...
