Carefully turn bed upside down on skid (make sure nothing is beneath that would scratch the bed ways). Turn it opposite direction from Powermatic logo plate to prevent damage to plate. 5.
8. 9. With assistance, raise bed and leg assembly right-side up. 7.7 Lamp holder set 1. Bed and leg assembly is heavy. Use care when lifting. Install shaft of lamp holder (F, Figure 9) into guard bracket hole, and tighten handle (G). 2. Install collar (H) beneath and tighten set screw on collar. Rotate the leveling feet as needed to establish level for the lathe. 10. Install headstock, toolrest base and tailstock, and both stop bolts (B, Figure 3). 7.
Figure 13 Figure 11 4. The guard can be pivoted to one of two positions: Operating mode, or tilted back for stock loading. 5. Pull up on plunger and begin tilting guard, then release plunger. When guard reaches either of the two positions, plunger will engage. (Swing lamp holder away for guard clearance.) 7.10 Optional accessories The following items are optional and purchased separately. See your Powermatic dealer for information. If you did not purchase an optional accessory, proceed to section 7.11.
Figure 16 4. Install elevating system (Figure 17) to bed extension with four 3/8" screws and washers, and to lathe leg with three 1/2” screws and washers (A, Figure 17). Note that top screw is installed from inside the leg and secured with the nylon nut (B). Refer to exploded view, section 17.5.1 if clarification is needed. 5. Install handwheel and tighten setscrew. Figure 14 7. Unscrew stop bolt from lathe bed (Figure 15), and insert it into hole at end of bed extension. Figure 15 7.10.
IMPORTANT TIP: It is unlikely that a full-size shelf can be completely built and then inserted between the Lathe legs. Therefore, construct the shelf in pieces and insert screws only after the shelf has been established beneath the Lathe. Shelf Style 1 (Figure 20) Lay two 2x6 boards flat upon the inner ledges. Shelf Style 2 (Figure 21) Lay two 2x6’s (or 2x4’s) on edge into the outer ledges. Figure 18 Cut two pieces from a plywood board, and screw them to the top edges of the 2x6’s.
8.0 Electrical connections Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury. The 4224B Lathe will operate on single phase or three phase, 230 volt power supply. Make sure the characteristics of your power supply match the power specifications on the lathe inverter. Figure 22 Before connecting to power source, be sure switch is in off position.
The inverter does not require any programming; it has been pre-programmed from the factory. The buttons on the face of the inverter should never be pushed at any time. Use only the controls on the front of the headstock. If you suspect a problem with the inverter or its settings, contact Walter Meier (Manufacturing) Inc., technical service at 1-800-274-6848. A lightning strike or power surge may cause the inverter to fail.
9.3 Tool support now be removed by holding body stationary while unscrewing cone. A 14” tool support is provided with your lathe. It is designed to allow adjustment for height, position on the bed, and angle to the work. 9.6 Indexer The indexer is used to create evenly spaced features in a workpiece, while keeping the lathe spindle locked; for example, when cutting flutes on a spindle blank with a router, while the spindle blank is secured between lathe centers.
9.7 Centers: Installing/removing 1. Disconnect lathe from power source. 2. To install a spur center or live center (a spur center should first be mounted to your workpiece; see section 11.4), clean tapered end of center and inside of headstock taper spindle, then push center into headstock spindle. 3. If at any time you will be reversing spindle rotation, make sure the two set screws in the face plate are tight! Failure to do this may cause the face plate to loosen from the headstock spindle. 6.
4. There should be sufficient slack in the belt to reposition it to the other steps on the sheaves. The label on the access door shows the required belt position. Figure 29 3. Install comparator dead center in the comparator bracket and tighten lock handle. See Figure 30. 4. Mount spur center with the spindle blank that you will be turning. Loosen tailstock locking handle, and slide tailstock until live center is about 1-inch from spindle blank, then tighten locking handle.
NOTE: You may have to tap the end of the spindle with a wood block to move it. (Never use a steel face hammer directly against the spindle.) Figure 32 5. The bearing lock nut should be tightened just enough to remove end play, and spindle should still rotate freely. Run the lathe for a time, and check for heat from the spindle bearings. If the bearings are running hot, the bearing lock nut is too tight and should be loosened slightly. 6.
10.0 Operating controls 11.0 Operation See Figures 33 and 34. The information which follows is general in nature and not intended to be a complete course in woodturning. Nothing can replace the knowledge gained by talking with experienced woodturners or consulting books or trade magazines. Above all, simple trial and error will aid in developing proficiency in the craft. (H) Vacuum on/off switch with gauge. (I) On/Off (headstock): Push in to stop lathe; pull out to start.
11.3 Spindle Turning Parting Tool - 1/8", used for scraping, making a cut-off, or to set diameters for sizing. Spindle turning takes place between the centers of the lathe. It requires a spur or drive center in the headstock and a live or dead center in the tailstock. A cup center rather than a cone center in the tailstock will often reduce the risk of splitting the stock. Figure 36 shows the basic profile shapes in spindle turning. Figure 36 11.
3. Drive the spur center about 1/4” into the workpiece, using a wood mallet or dead blow hammer as shown in Figure 38. Be careful that you do not split the workpiece. Never use a steel face hammer and never drive the workpiece onto the spur center while it is mounted in the Lathe spindle. used. Consult headstock. digital readout on the Figure 39 11.5 Cutting Techniques 11.5.1 Roughing Out 1. Begin with a large roughing gouge.
6. Add details to the workpiece with skew, parting tool, scraper or spindle gouge. 11.5.2 Beads 1. Make a parting cut for what is to be a bead to the desired depth. Place the parting tool on the tool support and move tool forward to make the full bevel of the tool come into contact with the workpiece. Gently raise handle to make cut to the appropriate depth. 2. Repeat for other side of the bead. 3.
11.6.1 Mounting Stock 11.6.2 Faceplate or Chuck? Use of a face plate is the most common method for holding a block of wood for turning bowls and plates: While faceplates are the simplest, most reliable method of holding a block of wood for turning, chucks can also be used. As 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. 1.
other gouges. Most average sized bowl work can be accomplished with a 3/8" or 1/2" bowl gouge. A 1/4" bowl gouge is best suited for smaller bowls and light finishing cuts. Larger 3/4" and 1" bowl gouges are only used for extremely large pieces. 10. 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. Large domed scrapers can also be used to help clean up the interior surfaces of bowls.
(NOTE: Try to make one, very light continuous movement from the rim to the bottom of the bowl to ensure a clean, sweeping curve through the piece. 12.0 Maintenance Should there be a few small ridges left, a light cut with a large domed scraper can even out the surface.) Before doing maintenance on the lathe, disconnect it from electrical supply by pulling out the plug or switching off main switch. Failure to comply may cause serious injury. 7.
13.0 Optional accessories These items, purchased separately, can enhance the functionality of your lathe. Contact your Powermatic dealer for more information.
