Grounding Instructions

Caution: This tool must be grounded while in use to protect the operator from electric shock.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-gr ounding c onductor and a groundi ng plug. T he plug m ust be plugged i nto a matchi ng outl et that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provi ded. If it will not fit the outlet, have the proper outl et installed by a qualifi ed electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipment-gr ounding c onductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equi pment-grounding conduct or to a live term inal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension cords that have thr ee- pr ong gr ounding plugs and three-pole r ec eptacles that accept the tool’s plug.

Repair or replace a damaged or worn cord imm ediately.

115 Volt Operation

As received from t he factory, your lathe is ready to run at 115 volt operati on. This lathe is int ended for use on a circuit that has an outlet and a plug that looks like the one illustrated in (A). A temporary adapter, which looks like the adapter as illustrated in (B), may be used to connect this plug to a two-pole receptacle, as shown in (B) if a properly grounded out let is not available. The temporar y adapter should only be used until a properl y grounded out let can be installed by a qualif i ed el ectrici an. This adap ter is not applicable in Canada. The green col or ed rigid ear, lug, or tab, extending from the adapter, must be connected to a perm anent ground such as a properly grounded outlet box, as shown in (B).

Lathe Tools

If possible, select only high quality, high speed steel turning tools with long handles. 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 pr ojects. See your JET distributor for a wide variety of JET woodturning tools.

Roughing Gouge - used for rapidly cut raw wood into round stock , see Figure 12.

Deep Fluted Bowl Gouge - used for turning bowls and plates, see Figure 12.

Spindl e Gouge - used for tur ning beads, coves and other details, see F igure 12.

Spear - fine scraping and delicate operations, such as the forming of beads, parallel grooves and shallow vees, etc , see Figure 12.

Skew - used to make vees, beads, etc., see Figure 12.

Square Scraper - used for diameter scraping and featureless scraping, etc, see Figure 12.

Large Domed Scraper - used to reduc e ridges on the interior of bowls, round edges of bowls, etc, see Figure 12.

Parting Tool - used to cut directly into the material, or to make a cut off. Also used for scraping and to set di am eters, see Figure 12.

For safety and best performance, keep tools sharp. If a tool stops cutting, or requires excessiv e pressure to make a cut, it needs to be sharpened. A number of brand name sharpening jigs and fixtures are available, however, a woodturner should l earn to sharpen tools freehand.

Mounting Workpiece Between Centers

Spindle turni ng takes place between the cent ers of the lathe. It requires a spur center in the headstock and a liv e center in the tailstock.

1. W ith a ruler locate and mark the center on

each end by going corner to corner, see Figure 13. Accuracy is not critical on full rounds but extremely important on stock where square sections are t o remain. Put a dimple in each end of the stock wit h an awl, or nail.

2. Extrem ely hard woods may requi re kerfs cut

into the spur drive end of stock, see Figure

13. You may need to dr ive the spur center into the stock with a wood mallet. Note: Never drive stock onto spur while it is mounted in the lathe spindle.

3. Install workpiece by inserting the attached

spur center into the spindle taper on the headstock.

4. Bring tailstock into position, lock it to the

bed, and advance quill with the handwheel in order to seat the live center into the workpiece. Lock the quill in place. Make sure the live center point is centered on your mark.

5. Move tool rest into position. It should be

parallel to workpiece, approximately at the centerline, and approximately 1/8" from the closest part of the workpiece. Lock tool rest body and tool rest in plac e.

6. Rotate workpiece by hand to check for

proper clearance from tool rest. Note: You may want to trim off the corners of a square workpiece to make turning a little easier, see Figur e 14.

7. Start lathe at lowest

the appropriate RPM for the size of stock, see Figure 7 page 10.

The position of the tool rest can be v aried t o suit the work and operator. After you become experienced with setting the tool rest changing the position will become second nature for the workpiece and comfort of the user.

speed and bring it up to

Stock Sele ct ion

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" lar ger than the finished di ameter and may require additional length to rem ove ends if requir ed. Larger stock should have the cor ners removed to produc e an octagon making t he piece easier t o rough down to a cylinder, see Figur e 14.

Roughing Out

1. Use a large roughing gouge and begin

cutting about 2” fr om the tailstock end of the workpiece. Place the tool on tool rest with heel of the tool on surfac e to be cut.

2. Slowly and gently raise tool handle until

cutting edge comes into contact with the workpiece. Work to the right towards the end of the workpiece. You never want to start at the end of a workpi ec e.

3. Now continue to work the rest of the

workpiece. Roll the flute (hollowed-out portion) of the tool in the dir ection of the cut, see Figure 15. Make long sweeping cuts in a continuous motion to rough the piece down to a cylinder. Keep as much of the bevel of tool as possible in contact with workpiece to ensure control and avoid catches. Note: Always cut down-hill, or from large diameter to small diameter. Al ways wo rk toward the end of a workpiece, never start cut ting at the end.

4. Once the workpiece is roughed down to a

cylinder, smooth it with a large skew. Pl ace the cutting point near the center of the chisel and high on the workpiece, see Figure 16. Touching one of the points of the skew to the spinning workpiece may cause a catch and ruin the workpi ec e.

5. Add details to the workpiece with skew,

spindle gouge, etc.

Coves

1. Use a spindle gouge. With the flute of t he

tool at 90 degrees to workpiece, touch the center of the cutting edge to the workpiece and roll in towards the bottom of the cove. Stop at the bottom; attempting to go up the opposite side m ay cause the t ool to catch.

2. Move tool over the desired width of cove.

3. W ith the flute facing the opposite direction,

repeat step 1 for ot her si de of cov e. Stop at bottom of cut, see Figure 18.

“V” Cuts

1. Use the long point of the skew. Note: Do

not press the long poi nt of the skew directl y into the workpi ece to creat e the "V"; t his will result in a burned, or burnished "V" with fibers being r olled up at both sides.

2. Li ghtly m ark the center of the "V" wit h the tip

of the skew.

3. Move the point of skew to the right half of

the desired width of y our cut , see Figure 19.

4. With the bevel parallel to the right si de of the

cut, raise the handl e and push the tool in to the desired depth.

5. Repeat from the left side. The two cuts

should meet at the bottom and leave a clean "V" cut.

6. Additional c uts m ay be taken to add to either

the depth or width of t he cut.

Parting

1. Place parting tool on tool rest and raise the

handle until it starts to cut and continue to cut to the desired dept h.

2. If the cut is deep a clearance cut should be

made along side the first c ut to prevent the tool tip from burning.

Beads

1. Place parting tool on tool rest and move tool

forward to make t he f ull bev el of tool come in contact with workpiece. Gently raise handle to make cut to appropr iate depth.

2. Repeat for other side of t he bead.

3. Using a small skew or spindle gouge, star t in the center between the two cuts and cut down each side to form the bead. Roll the tool in direction of cut.

Sanding & Finishing

Leaving clean cuts will reduce the amount of sanding required. Adjust lathe to a finishing speed, and begin with fine sandpaper (120 grit or finer). Coarser sandpaper will leave deep scratches that are difficult to remove, and dull crisp detail s. Fold t he sandpaper int o a pad; do not wrap sandpaper around your fingers or the workpiece. To apply a fini sh, the workpiece can be l eft on the lathe. Tur n off lathe and use a brush, or cloth to apply the finish. Remove excess finish before restarting lathe. Allow to dry and sand again with 320, or 400 grit sandpaper. Apply additional coats of finish and buff.

Face Plate & Bowl Turning

Face plate turning is normally done on the inboard side of the headstock ov er the bed, see Figure 20. You must move headstock to the end of the lathe bed for larger workpieces.

Mounting Stock

Use of a face plat e i s the m ost c ommon m ethod for holding a block of wood for turning bowls, and plates, see Fi gur e 21.

1. Select stock at least 1/8" to 1/4" larger than the dimension on the desired finished workpiece.

2. True one surface of workpiece for mounting against the face plate. It is best to leave extra stock against the face plate that can be cut off when the workpiece is finished.

3. Using t he f ace plat e as a templat e, mark t he location of the mounti ng holes, and drill pil ot holes of the appropriate size. If the mounting screws on the face plat e interf ere with the workpiece, a waste block can be mounted to the face plate and then the waste block mounted to the workpiece by gluing or screwing, see Figure 21.

4. Both waste block and workpiece should have good flat surfaces.

5. Push in the spindle lock and thread face plate and workpiece onto spindle. Tighten set screws in face plate when secure.

Face Plate or Chuck

While facepl ates are the sim plest, most reliabl e method of holding a block of wood for turning, chucks can also be used. A chuck is not a requirement but is handy when working on more than one piece at a time. Rather t han removi ng screws, you simply open the chuc k and change workpieces. The most popular ones are four jaw scroll chucks with a variety of jaws to accomodate different size tenons. Most also come with a screw chuck as well.

Wood Selection

Firewood is the cheape st, most widely av ailable stock to use while learning to turn bowls. Develop skill with each tool before attempti ng to make a finished piece. It is best to start with dry wood, without worrying about drying or distortion. Once turning becomes comfortable, try green wood which cuts very easily. As the turner gains experience, he or she will find extraordinary grain and figure in the form of burls, crot c hes and bark inc lusions.

Checks & Cracks

Green wood will check and crack. For best results, leav e logs in as long lengths as you can handle. As the material starts to dry, surface cracks will develop on the ends of the log. Cut off two to three inches and you should f ind good, sound wood. Also cut the log i n half along the pith to avoid having it in the finished piece. Most checks radiat e from the pith. As you turn bowls from green wood, make sure you maintain a consistent wall t hickness throughout the pi ece. Leaving a piece thick in some areas and thin in others will cause the wood to dry unevenly and promote checks and crac k s.

Distortion

Distortion is a problem associated with turning green wood. I t will vary from one ty pe of wood to the next. Typicall y, fruitwoods tend to di stort more than others. It also varies with the tim e of year the tree was cut and how the logs are stored.

Tools for Bowl Turning

The deep fluted bowl gouge is the most essential and versatile tool for most bowl and faceplate style turning. The bowl gouge is heavier and easier t o control t han other types of

gouges. It also allows removal of wood much faster and wit h less vibration t han 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 f or smaller bowls and light fi nishing c uts. Larger 3/4" and 1" bowl gouges are only used for extremely large pieces.

Large domed scraper s can also be u sed to help clean up the interi or surfaces of bowls. A light touch with the scraper sli ghtly tilt ed will elimi nat e some of the ridges left by a bowl gouge.

To Shape Outside of Bowl

1. Odd shaped burls, crotches and other irregular shaped blanks require special preparation before mounting in a chuck, or onto a faceplate. Remove the bark, if there is any, from what appears to be the c enter of the top of workpiece.

2. Driv e spur center into the top of workpiece with a wood mallet.

3. Slip spur center into headstock taper and bring the tailstock, with a live center into position. Loc k tailst ock to bed and adv ance spindle in order to seat the cup center into workpiece, see Figure 22. Tighten quill lock.

4. Position tool support just below the centerline and about 1/4" from the workpiece. Note: For larger outboard turning, an optional outboard turning stand is used to place the tool support , see your JE T distributor.

5. Turn workpiece by hand to ensure proper clearance.

6. St art lat he at lowest speed and bri ng i t up t o the maximum safe speed for the size of work to be turned, see Figure 7 on page 10. If the machine starts to vibrate, lower the speed until vibr ation stops.

7. Rough out the outside of the bowl with the 1/2" deep fluted bowl gouge, holding the tool firmly against your hip. For best control, use your whole body to move the gouge through the workpiec e.

8. As the bowl takes shape, work on the bottom (tailstock end) to accomodate attaching a face pl ate, see Figure 22.

9. Tur n a short t enon (about 1/ 8" l ong) t he size of the hole in the faceplate, see Figure 22. This will all ow centeri ng the workpi ece when the faceplate is attached. Note: If you plan to use a chuck, turn a tenon of appropriate length and diameter to fit your chuck.

10. S top the lathe, remove workpiece and attach face plate, or chuck .

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. T his will be removed later.

To Shape In terio r of Bo wl

1. Stop lathe and move tailstock away. Remove center from tailstock to prevent bumping it with el bow.

2. Adjust tool support in front of the bowl j ust below centerli ne, at a right angle to t he lathe bed.

3. Rotate workpiece by hand to check clearance.

4. Face off top of bowl by making a light shearing cut acros s the workpiece, from rim to center.

5. Place 1/2" bowl gouge on tool rest at center of the workpiece with the flute facing t op of bowl. The tool handle should be level and pointed toward four o' cl oc k , see Figure 23.

6. Use left hand to control cutting edge of gouge, while right hand swings tool handle around toward your body, see Figure 23. The flute should start out facing top of workpiece, and rotate upward as it moves deeper into the bowl to maintain a clean even curve. As tool goes deeper into bowl, progressiv ely work out t oward rim . It may be necessary to t urn the tool r est into the work piece as you get deeper into the bowl. 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 workpiece. Should there be a few small ridges left, a light cut with a large domed scraper can even out the surface.

7. Develop wall thickness at the rim and maintain it as you work deeper into t he bowl. When the interior is finished, move tool support to exterior to re-define bottom of bowl. General rule of thumb: the base should be approximately 1/3 the overall diameter of t he bowl.

8. Work the tight area around faceplate or chuck with 1/4" bowl gouge.

Sanding and Finsihing

1. Remove the toolrest and adjust lathe speed to the appropriate finishing speed. High

speed can build friction while sanding and cause heat check in some woods.

2. Begin with fine sandpaper 120 grit and progress through each grit, using only light pressure. Coarser sandpaper tends to leave deep scratches that are hard to eliminate. Use power-sanding techniques to avoid concentric sanding marks around your finished pi ece. Avoi d rounding over the rim and foot with sandpaper. Try to keep details cri sp. Finish sanding with 220 grit .

3. Remove sanding dust with tack rags, or compressed air and, with lathe turned off, apply first coat of finish. Let stand for several minutes, wipe off excess. Allow to dry before sanding again with 320 or 400 grit sandpaper.

4. Turn lathe back on and make a separation cut through the base. Stop at about 3" and use a small fine tooth saw to separate the bowl from the waste.

5. Appl y additi onal finish coats and al low to dry before buffing.

Adjusting Clamping Mechanism

The clamps are pre- set at the fac tory and should not need any adjustment. However, if adjustment is needed remove the stud (A, Fig.

24). Loosen the locking handle and slide the headstock, tailstock or tool rest to the edge of the bed and slightl y turn the hex nut (B, Fig. 24). Slide back into position and test the handle to make sure it securely locks.

Changing the Belt and Bearings

Changing belt and bearings can be a difficult task, and should be performed by a JET authorized repair station. Remove headstock and take into a repair station for servicing.

1. Disconnect the machine from the power source!

2. Loosen the locking handl e (C, Fig. 25), and lift up on the tensioni ng handle (D, Fig. 25) to remove tension from the poly v-belt.

3. Open door (E, Fig. 25) , and remove the bel t (F, Fig. 25) from the lower pul ley.

4. Loosen t wo set scre ws in the handwheel ( G, Fig. 25) and remov e.

5. Loosen socket head cap screw enough to unthread the cl amping nut (H, Fig. 25).

6. Loosen two set screws in the right hand pulley (I, Fi g. 25).

7. Loosen set screw in the coll ar (J, Fi g. 26)

8. Use a wood dowel, or aluminum stock to knock spindle t owards the tai lstock. Use a

material that is softer than the spindle so you do not mushroom end of spindle. Go

only far enough to remove belt from spindle, see Figure 26.

9. Now you can replace the belt or bearings. There are two bearings #5, and 10 that can be seen in “Headstock Assem bly,” page 24.

10. To reassemble reverse the procedure. Note: When reinstalling clamping nut thread it on to the spindle until its snug. Then back off slight ly and tighten t he socket head cap screw.

to workpiece and headstock.
