Grounding Instructions

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 conductor and a groundi ng plug. The plug m ust be plugged into a matc hing outlet that is properly installed and grounded in accor dance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the out let, have the proper outlet installed by a qual ified 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 conductor. 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 gr ounded. Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that acc ept the tool’s plug.

Repair or replace a damaged or worn cord imm ediately.

115 Volt Operation

As received fr om the factory, your sander is ready to run at 115-volt operation. This sander, when wired for 115 volts, is intended for use on a circuit that has an outlet and a plug that looks the one illustrat ed in Figure A. A temporary adapter, which looks like the adapter as i llustrated in Figure B, may be used to connect this plug to a two-pole receptacle, as shown in Figure B if a properly grounded outlet is not available. T he temporary adapt er should only be used until a properly grounded out let can be instal led by a qualified elec trician. This adapte r is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box, as shown in Fi gur e B.

The use of an extension cor d is not r ec ommended. However, if you must use one make sure your extension cord is in good condition. Be sure to use one heavy enough to carry the current your machine will draw. An undersized cord wil l c ause a drop in the line voltage resulting in power l oss and overheating. The following table shows the correct size to use depending on the cord length needed and the nameplate amper e r ating. If in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier the cord.

230 Volt Operation

If 230V, single-phase operat ion is desired, the followi ng instructions must be followed:

1. Disconnect th e machine from the power source.

2. This lat he is supplied with four m otor leads that are connect ed for 115V operation, as shown in Figure A. Reconnect these four motor leads for 230V operation, as shown in F igure B.

3. The 115V attachment plug (A), supplied with the lat he, must be replaced with a UL/CSA listed plug suitable for 230V oper ation (D). Contact your local Authoriz ed Service Center or qualifi ed electrician for proper procedur es to install the pl ug. The lathe must com ply wit h all local and national c odes after the 230-volt plug is installed.

4. The lathe with a 230 volt plug should only be connected to an outlet having the sam e configurati on (D). No adapter is available or should be used with the 230-volt plug.

Important: In all cases (115 or 230 volts), make certain the receptacl e in question is properl y grounded. If you are not sure, have a regi ster ed electrician check the receptacl e.

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 f ollowing tools provide the basic s for most woodturning projects. See your JET distribut or for a wide variety of JET woodturning tools.

Roughing Gouge — used for rapidly cut raw wood into round stock , see Figure 10.

Deep Fluted Bowl Gouge — used for turning bowls and plates, see Figure 10.

Spindle Gouge — used for turning beads, coves and other detai ls, see Figure 10.

Spear — fine scraping and delicat e operations, such as the forming of beads, parallel grooves and shallow vees, etc , see Figure 10.

Page 13

Lathe Tools (continued)

Skew — used to make vees, beads, etc., see

Figure 11. Square Scraper — used for diameter scraping

and featureless scraping, etc, see Figure 11. Large Domed Scraper — used to reduce ridges

on the interior of bowls, round edges of bowls, etc, see Figure 11.

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 11.

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 num ber of brand name sharpening jigs and fixtures are available, however, a woodturner should learn 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. With a ruler locate and mark the center on

each end by going corner to corner, see Figure 12. Accuracy is not critical on full rounds but extremely important on stock where square secti ons are to remain. Put a dimple in each end of the stock with an awl or nail.

2. Ext remely hard woods may r equire kerfs cut

into the spur drive end of stock, see Figure

12. You may need to drive 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 cor ners of a square workpiece to make turning a little easier.

7. Start lathe at lowest the appropriate RPM for the size of stock, see Figure 6 page 11.

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

speed and bring it up to

Page 14

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" larger than the finished di ameter and may require additional length to rem ove ends if required. 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 13.

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 the tool rest 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. Wor k to t he ri ght t owards the end of the workpi ece. You never want to start at the end of a workpiece.

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 14. Mak e long sweeping cut s i n a continuous moti on to rough the piece down to a cylinder . Keep as much of the bevel of the tool as possible in contact with the workpiece to ensure control and avoid catches. Note: Always cut downhill , or from large diameter to small diameter. Always work toward the end of a workpiece, never start cutti ng at t he end.

4. Once the workpiece is roughed down to a cylinder, smooth it with a large skew. Place the cutting point near the center of the chisel and high on the workpiece, see Figure 15. 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.

Page 15

Beads

1. Place the parting tool on the tool rest and move the tool forward to make t he full bev el of the tool contact the workpiece. Gently raise handle to make cut to the appropriat e depth.

2. Repeat for other side of the bead.

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

Coves

1. Use a spindle gouge. With the flute of the tool at 90 degrees to the workpiece, touch the center of the cutting edge to the workpiece and roll in towards the bott om of the cove. Stop at the bottom; attempting to go up the opposite side m ay cause the tool to catch.

2. Move the tool over the desired widt h of the cove.

3. W ith the flute facing the opposite direction, repeat step 1 for other side of cov e. Stop at bottom of cut.

“V” Cuts

1. Use the long point of the skew. Note: Do not press the long poi nt of the skew directly into the workpiece to create the "V"; this will result in a burned or burnished "V" with fibers being r olled up at both sides.

2. Lightly mark the center of the "V" with the ti p of the skew.

3. Move the point of the skew to the right half of the desired widt h of your c ut.

4. With the bevel parallel to the right side 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 cuts may 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 c ut should be made alongside the first cut to prevent the tool tip from burning.

Page 16

Sanding and Finishing

Leaving clean cuts will reduce the amount of sanding required. Begin with a fine sandpaper (120 grit or finer). Coarser sandpaper will leav e deep scratches that are dif ficult to remove, and dull crisp detail s. Fold the sandpaper into a pad; do not wrap sandpaper around your fingers or the workpiece.

To apply a finish, the workpiece can be left on the lathe. Turn off lathe and use a brush, or cloth to apply the finish. Remove excess finish before restarting l athe. Allow drying and sanding again with 320 or 400 grit sandpaper. Appl y additional coats of fini sh and buff.

Face Plate and Bowl Turning

Face plate turning is normally done on the inboard side of t he headstock over the bed see Figure 19. You must pivot the headstock 180° 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.

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

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

3. Using the fac eplate as a template, mark t he location of the mounti ng holes, and drill pil ot holes of the appr opriate size. If the mounting screws on the faceplate interfere with the workpiece, a waste block can be mounted to the faceplate and then the waste block mounted to the workpiece by gluing or screwing, see Fi gur e 20.

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

5. Push in on the spindle lock and thread face plate and workpiece onto the spindle. Tighten setscrews in the faceplate when secure.

Page 17

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 removing screws, you simply open the chuc k and change workpieces. The most popul ar ones are four jaw scroll chucks with a variety of jaws to accommodate 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 pi ece. It is best to start wi th 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 and Cr acks

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 in half along the pith to avoid having it in the finished piec e. Most checks radiate from the pith. As you turn bowls from green wood, make sure you maintain a consistent wall thickness throughout the piece. 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. It will vary from one type of wood to the next. Typically, fruitwoods tend to distort more than others do. It also varies with the tim e of year the tree was cut and how the logs are stored.

Too ls 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 cuts. 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 interior 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.

Page 18

To Shape the Outside of a Bowl

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

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

3. Slip the spur center i nto t he headstock t aper and bring the tailstock, with a live center, into position. Lock the tailstock to the bed and advance the spindl e in order to seat the cup center into workpiece, see Figure 21. Tighten the quill lock.

4. Position the tool support 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 the workpiece by hand to ensure proper clearanc e.

6. Start the lathe at t he lowest speed and bring it up to the maximum safe speed for the size of work to be tur ned, see Figure 6 on page

11. If the machine starts to vibrate, lower the speed until the vibration stops.

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

8. As the bowl takes shape, work on the bottom (tailstock end) to accommodate attaching a face pl ate, see Figure 21.

9. Turn a short tenon (about 1/ 8" l ong) the si ze of the hole in the faceplate, see Figure 21. This will all ow centeri ng the workpi ece when the faceplat e is attached. Note: If you plan to use a chuck, tur n a tenon of appropr iate length and diam eter to fi t your c huc k.

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

11. Finish turning the outside of the bowl with 1/2" or 3/8" bowl gouge. Leave additional

material at the base of the bowl for support while turning the interior. This will be removed later.

Page 19

To Shape the Interior of a Bowl

1. Stop the lat he and move the tailstock away. Remove the center from the tailstock to prevent bumpi ng it wit h y our elbow.

2. Adjust the tool support in front of the bowl just below the cent erline, at a right angle to the lathe bed.

3. Rotate the workpiece by hand t o check the clearance.

4. Face off the top of the bowl by making a light shearing c ut across the workpiece, from rim to center.

5. Place the 1/2" bowl gouge on the tool rest at the center of the workpiece with the flute facing the top of the bowl. The tool handle should be level and pointed toward four o'clock, see Figure 22.

6. Use your left hand to control the cutting edge of the gouge, while your right hand swings the tool handle around towards your body, see Figure 22. The flute should start out facing the top of the workpiece, and rotate upward as it moves deeper into the bowl to maintain a clean even curve. As the tool goes deeper into bowl, progressively work out toward the rim. It may be necessary to turn the tool rest into the workpiece, as you get dee per 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 the wall thickness at the rim and maintain it as you work deeper into t he bowl. When the int erior is fi nished, mov e the tool support to the exterior to re-define the bottom of the bowl. General rule of thumb: the base should be approximately 1/3 the overall diameter of the bowl.

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

Sanding and Finishing a Bowl

1. Remove the tool rest and begin with a fine grit 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 piece. Avoid rounding ov er the rim and foot with sandpaper. Try to keep the details cri sp. Finish sanding with 220 grit .

2. Remove sanding dust with tack rags, or compressed air and, with the lathe turned off, apply the fir st coat of finish. Let it stand for several minut es and wipe off the excess. Allow it t o dry before sanding agai n wit h 320 or 400 grit sandpaper.

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

4. Apply additional fi nish coats and all ow to dry before buffing.

Adjusting the Clamping Mechanism

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

23). 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. 23). 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. Place the belt in its highest speed range. Do not change speeds while changing t he belt or bearings.

2. Rem ove the belt c over, and rem ove the belt from the lower pulley , see Figure 24.

3. Loosen the two setscr ews in the handwheel enough to unthread the h andwheel (C, Fig.

24).

4. Loosen the socket head cap screw enough to unthread the clamping nut (D, Fig. 24).

5. Remove one e-ring ( E, Fig. 24) fr om spindle.

6. Loosen the two setscrews in the ri ght hand pulley (F, Fi g. 24).

7. Use a wood dowel, or aluminum stock to knock the spindle towards the tailstock. Use

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

Go only far enough to remov e the right hand pulley and belt from spindle, see Figure 25 when changing the bel t. Note: Mark the key way on the pulley for easy reference when reassembling.

8. Now you can replace the belt or bearings. There are three bear ings #6, 9 and 43 that can be seen in the “Headstock Assembly,” page 24.

9. To reassemble rev er se the pr oc edur e. Note: Key way alignment is critical for installment and proper operation. Do not force the pulley. 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.
