RECEIVING Remove the lathe from the shipping container and check for damage. Report any damage to your distributor immediately. Accessories are packaged in a separate carton which will be on the shelf of the machine stand. Clean protective coating from the bed, spindles, work rest and face plate with kerosene or a good commercial solvent. Read the instruction manual thoroughly for assembly, maintenance, operation and safety instructions.
Tool Support The tool support (shown in Figure 5), is designed to allow adjustment for height, position on the bed, and angle to the work. Your 4224 lathe comes standard with the 14" tool support. Other supports are available; consult the "Optional Equipment" list on page 24. Periodically the tool rest should be disassembled and the parts cleaned and oiled to provide free movement of the parts to ensure good clamp action.
TOOLS If possible, select only quality, high speed steel turning tools. High speed tools hold an edge and last longer than ordinary carbon steel. As one becomes proficient in turning, a variety of specialty tools for specific applications can be acquired. The following tools provide the basics for most woodturning projects: Large Roughing Gouge - 1" to 1-1/4", used to eliminate waste wood. Skews - 1-1/2" and 1" or 1-1/4", used to make finishing cuts and details.
FIGURE 2 STOCK SELECTION Stock for spindles should be straight grained and free of checks, cracks, knots and other defects. It should be cut 1/8" to 1/4" larger than the finished diameter and may require additional length to remove ends if required. Larger stock should have the corners removed to produce an octagon making the piece easier to rough down to a cylinder. 1. With a combination square or plastic center finder, locate and mark center on each end of stock.
ROUGHING OUT: 1. Begin with a large roughing gouge. Place the tool on the tool support with the heel of the tool on the surface to be cut. 2. Slowly and gently raise tool handle until cutting edge comes into contact with the workpiece. 3. Beginning at the tailstock end of the workpiece, roll the flute (hollowed-out portion) of the tool in the direction of the cut, Figure 6. Make long sweeping cuts in a continuous motion to rough the piece down to a cylinder.
PARTING OFF: 1. Use parting tool. 2. Adjust lathe speed to lower RPM for parting through a workpiece. 3. Place tool on tool support and raise the handle until it starts to cut and continue to cut towards the center of the workpiece. 4. Loosely hold on to the piece in one hand as it separates from the waste wood. SANDING and FINISHING: Leaving clean cuts will reduce the amount of sanding required. Adjust the lathe to a low speed, and begin with fine sandpaper (120 grit or finer).
there are dozens of chucks to choose from, the woodturner should first consider all the different types of turning that will be done, and read reports or discuss with other turners who own chucks before making a decision. A chuck is not a requirement but is handy when working on more than one piece at a time. Rather than removing screws, you simply open the chuck and change workpieces. The most popular ones are four jaw scroll chucks with a variety of jaws to accomodate different size tenons.
10. Stop the lathe, remove workpiece and attach face plate or chuck (see "Mounting Stock" above). 11. Finish turning the outside of bowl with 1/2" or 3/8" bowl gouge. Leave additional material at base of bowl for support while turning interior. This will be removed later. TO SHAPE INTERIOR OF BOWL: 1. Stop lathe and move tailstock away. Remove center from tailstock to prevent bumping it with elbow. 2. Adjust tool support in front of the bowl just below centerline, at a right angle to the lathe ways. 3.
TROUBLE-SHOOTING (4224 Lathe) PROBLEM POSSIBLE CAUSE SOLUTION Excessive vibration. 1. Defective spindle bearings. 2. Worm or defective belt. 3. Defective motor. 4. Workpiece warped, out-of-round, has major flaw, or was improperly prepared for turning. 1. Replace bearings. 2. Replace belt. 3. Replace motor. 4. Correct problem by planing or sawing, or scrap workpiece. Motor or spindle stalls. 1. Excessive cut. 2. Defective motor. 3. Excessive belt wear. 4. Improper belt adjustment. 1.
