6" DELUXE JOINTER OPERATORS GUIDE The 6" DeIuxe Jointer i s light in weight, ruggedly

designed, and has a large working capacity. This ma- chine is accurately a s s e ~ b l c d and equipped for use in sash, door, furniture, and cabinet factories, contractors, box manufacturers, pattern, woodworking, and main- tenance shops, schoo!~, and many other woodworking and industrial plants and shops.

It can be used for the following operations: Jointing edges of stock, jointing ends of stock, jointing warped pieces, jninting thin stock, jointing narrow stock, rab- beting, beveling. taper cutting, stop chamfering. and many other additional operations.

The jointer is so named because of the type oI work it is designed to do, namely the jointing or planing of edges on materials so that they can be glued or joined together. The jointer is sometimes erroneously re- ferred to a s a planer, but the machine differs from a planer in that it is designed to work the edges of mate- rials rather than plane surfaces.

Maximum depth of cut is 5 inch. The maximum width of cut is 6 inches. The overall length of the work , table is 42v8 inches. The overall dimensions of the machine are: 14 inches wide, 473h itches long, and 33% inches high on our steel stand.

IMPORTANT Rockwell Jointers are carefully tested and inspect-

ed before shipment, and if properly used will give perfect results. However, certain adjustments are necessary in service, and if you are to receive the ittmost from your machine, i t is imperative that you read the following instr~ctionk carefully.

There is considerable risk in operating a jointer, con- sequently the operator cannot be too careful. Under no conditions should an inexperienced operatar attempt to operate the machine without first using scrap pieces of material to get the "feel" of the machine.

Refer to the photographs, drawings, and Table I to identify the parts mentioned in t he following instructions.

CONSTRUCTION FEATURES The base, frant, and rear work tables are made of

sturdy gray iron castings to produce maximum rigidity between these parts. T h e front and rear tables are finished ground af te r assembly on t he base casting. This operation assures the t rue alignment necessary for accurate work and is a feature found on larger and more expensiv~ machines only.

The cutter head suns In two single row sealed and shielded baIl bearings, which are pre-lubricated for their entire life. I t has three high-speed steel knives which can be easiIy adjusted and securely lacked in the dovetail grooves' of the cutter head.

The safety knife blade guard gives maximum protec- tion to the operator at all times. The t~nsioning mecha- nism enables the operator to give the correct tension to the safety knife blade guard for any desired operation. See Fig. 3.

The guide fence is easily clamped to the machined way of the front table casting. The guide fence can be moved the entire width of the table and clamped in position in a minimum amount of effort and time. See Fig. 4. It also can be tilted to any desired position lip to 45 degrees to the right or left. See Fig. 5. Th is fence guides t h e work to the full depth of the front \r,ork table past the revolving knives of the clutter head and well onto the rear zable.

The raising and lowering mechanisms of the front and rear tables are operated by hand-wheels with a free turning hand grip. and which are conveniently located in the front of the machine, one on the right

hand side,aAd one on the left hand side. See Fig. 6. The rear table can be locked on the right side in the rear of the rnarhine at the desired height by means uf a square head set screw. See Fig. 18. T h e front w o r k table can be locked at any desired height by means of a lock stud with a hand knob on the right side in the rear of the table casting. See Fig. 18.

The depth scale located on the base casting on the front of the machine and the tilting angle scale located on the fence segment are accurately graduated and have been made very legible for making any desired setting required. See Fig. 3 and 7.

To compensate for wear of the front and rear tables in relation to the base casting, we have incor- porated into this machine gibs t o maintain its orig- inal tight sliding fit a t all times. These gibs can be drawn up 'by means of headless set screws on the right side of each table casting. See Fig. 8.

MOTORS, PULLEYS AND V-BELT For light duty work a yt h.p. motar will furnish

ample power for this machine. For medium duty work a '/z h.p. motor will be mote effective. Use a constant speed motor. In commercial and industrial plants and shops, we

recommend a 3J4 h.p. motor be purchased with the

machi1:e since continupus duty work can easily be accomplished. Always use 3 phase power whenever i t is available.

Fig. 4. Showing Frnre and Start of Matcrial.

The motor speed with 60 cycle power and 1725 rpm, will run the cutting head at 4500 rpm. This speed is obtained with a 234'' cutter head pulley NO. 5275 and a 7" motor pulley No. 5700. Please specify when or- dering the motor pulley the correct bore to fit the motor shaft.

For 50 and 25 cycle current, use a 1425 rpm motor, which will run the cutter head at 3700 rpm. This speed is obtained with a 294" arbor pulley No. 5275 and a 7" motor pulley No. 5700. Please specify when ordering the mator pulley the correct bore to fit the motor shaft.

Use V-belt No. 560 which has an outside circum- ference of 58.31" in conjunction with the above mote- and arbor pulleys when it is mounted on our steel stand. Consult your Rockwell dealer if yon need a belt of any other length t o fit special conditions.

ASSEMBLY Wipe the prot~ctive coating thoroughly from

all parts of this machine. Unpack the other items in the separate cartons which come with the jointer and wipe the protective coating from these parts. In choosing a location for the machine be sure to

allow enough clearance in front of and behind the work tables for jointing long pieces,

Slide the guide fence in the machined way of the front tab le casting and clamp it a t any desired posi- tion along the width of the work tables.

Having decided upon the arrangement most suit- able for your needs, fasten the base to the machine stand, using the proper hexagon head cap screws into the holes provided in the base casting,

Before installing the motor on the machine stand, make sure it rotates in the right direction. The cut- ter head must rotate forward on top. If your motor suns in the wrong direction, reverse it according to the manufacturer's instructions, or In the case of a double shaft motor, turn it end for end.

The correct tension of the V-belt is such that t t ? V-belt can be flexed approximately 1 inch out ol line, using finger pressure midway between the cut- ter head pu>ley and the motor pulley.

Mount the motar pulley on the motor shaft with its hub extending away from the motor and tighten

it i n place. To prevent excess wear and ioss of power, the V-belt must run true. Place a straight edge across the faces of the pulleys and shif t the motor pulley on its shaft until it is in line and tighten its set screw. PIace zheV-belt over the arbor pulley, then stretch the V-belt over the motor pulley.

POWER CONNECTIONS Before connecting the motor to the power line, be

sure the electric current is of the s a k e character- istics as stamped on the motor name plate.

Do not connect the motor to a circuit which will be overloaded. If an extension cord is used, be sure that t he proper size of wire is used when connecting the machine to the power line to obtain proper volt- age. Using too small a wire will cause an excess loss of power. All line connections should make good contact.Runningon tow voltage will injure the motor.

LUBRICATION We suggest using a good grade of light grease on

the steel adjusting screws for the raising and lowet- I, i n g mechanisms of the front and rear work tables.

Occasionally apply a few drops of light machine oil to the gibs on the right s ide of each work table so the tables wilI slide freely in relation to the base casting.

OPERATING ADJUSTMENTS The controls and adjustments described below are

important for accuracy and convenience in various operations. Follow these directions for best results.

Rear Table and Knife Adjustment Accurate cuts are possible only when the knives of

the cutter head are parallel to the work tables and project equally from the cutter head. Upon receiv- i n g this jointer it is best to check this a l i ~ n m e n t .

To check this alignment proceed as follows: Raise the rear table by means of the hand-wheel on the left side of the base casting until i t is exactly level with the steel knives of the cutter head at their highest point of revolution. Place a steel straight edge on the rear table, extending aver the cutter head as shown in Figure 9. Rotate the cutter head by hand. The blades should jus t touch the straight edge. If a knife 1s too high or too low at either end. loosen the screws which lock i t in position lightly, and shift t he steel

a piece of woorI approximately R to 12 inches l o n ~ ~Iowly past the knives of the cutter head: i t should

I rest firmly on both machitlet1 5t1sfaces of the work table< and the machined surface of the guide fence as ~ h o w n in Figure 12, with no open space under the tinislied cut.

After this adjustment has been properly made, lock the rear table in position by t ightening the special ,square head lock scrrw on the right side of the rear table. In addizion we suggest tightening the gih xcrcws of the rear table.

Re-Setting Knives h f t e r 171: steel knives have been removed from the

ccttcr head, care must be used in re-setting them.

Fig. V 3. Showing Guide Fence.

Each knife blade should be placed in its groove, so !he rear edge of the bevel on the knife projects '/ls inch beyond the surface of the cutter head. Slip the knife lock bar into place and tighten the hexagon head set screws Iightly. Adjust the knives for a true cutting circle, using the straight edge as described under "Rear Table and Knife Adjustments." Tight- en all lock screws securely. W e suggest jointing the knives lightly before cutting any stock.

i Adjusting the Gibr c

The machined femaIe dovetail slide of the front and rear table castings ride in relation to the ma- chined male dovetail sIide of the base casting. On the right side between each table and base casting we have incorporated a steel gib to take up all play between these machined surfaces. This adjustment is carefuIly made at the factory, but we suggest re- checking each table before operating t h i ~ machine to see i f any play does exist.

-

I f the front and rear table is t o o hard to be raised m or lowered, or i f the tables are too loosely set,. an adjustment is needed. To make this adjustment pro- ceed as follows: Loosen or tighten all of the cone pointed gib screws provided on the right side of the

base casting approximate ly I , t u r n each. Be sure t o loosen o r t ighten each se t screw t h e same amount t o obtain a good t igh t slidi11g fit between the _table and t h e base cas t lng. We suggest the operator t ighten the uppermost set screw of the table f i r s t t hen the bottom set screw. a n d finally all of the intermediate set screws.

Raising and Lowering Gables

Each work table can be raised or lowered the amount '

needed independeritly of one arlothei. To raise o r Iower the front w o r k table, first loosen the hand knob on the right slde of it. The table can then be raised by turn- ing the hand-wheel which is located on the left side and in front of the table casting, to the left and lowered by tu rn ing the hand-wheel in the opposite direction. See Fig. 18. T h e pitrh o: + h e adjusting screw on which the raising and lowering mechanism rides is such that one complete turn of the hand-wheel move! the table approximately 1 32 inch. After making the adjust- ment needed, lock the table in posltlon by tightening the hand knob on the right side of the table casting. S e e Fig. 18.

The sear work table can be raised or lowered by first loosening the special square head lock scrzw on t he right side cf the rear tahle casting. See Fig. I&. TO raise or Iower the rear table is acc3mplished in the same manner a s raising and lowering the front table. Be sure to t ighten the special square head set screw on t he right side of t h e rear table casting after the proper adjus tment has been made.

Depth af Cut

'The amount of material removed by a single cut

t can be any thtckness up to !/, inch. For most jointing

+ o ~ e r a t i o n s the dznth of cut is controlled by raising or lowering the front work table the amount rieeded, us ing the hand-wheel on the left side of the table castlng.

Guide Fence Adjustments

Moutit the guide fence orr the frorir work ta1)lr: by slidiric the cross s l i d c plate into the r ~ ~ a c h i ~ ~ e ( l way of the f ront table casting. This fence i s conver~icr~t- ly tlsctl for yo~nting the edges of s tork, jointing thirl stock. jointing short s tock, r a b b e t i n g stock. beveling stock, taper in^ s t o c k , and nlany other s in~i las opera- tions. I t g i ~ i d c s thr work the full length of t h e front table. paat thc cutter head well onto the rear table. S r e Fig. 13.

T h e fence can easily be locked at any positiol, across the width of the front work table. To release the fence so it can be moved to the desired position. g r ip the d u a l control handle firmly and move it out until: i t engages the acorn n u t , turning the handle toward the left until the acorn nut becomes loose. Sec Fig. 14. With a firm hand grip an the top of the fence bady, slide t h e fence to the desired position. The guide fence can only be stid t o the r ight u n t i l it is parallel with the right edge of the work tables. Clamp the fence in the desired posrtion by turning the dual control handle, engaging the acorn nut, to the right.

The fence can be tilted 45 degrees to the left or right. T o tilt the fence to the left , grip the dual con- t ro l , handle with a firm hand, moving it inwardly until: it engages a hexagon nut and turn it to the Teft to loosen the nut. With a firm hand grip on the top of the fence body, tilt it to the desired angle. Turn the dual control handle to t he right, engaging the hexagon nut to lock it in position. See Fig. 15.

To tilt the fence to the right, grip the dual controI handle and move it inwardly until i t engages the hexagon nut and turn to the left to loosen it. Wi th a firm hand grip on the top of the fence, tilt it sIEgllt- Iy to the left and with the other hand, swing the stop block. which is attached to the crcss sIide plate, to the rear position until it is parallel to the fence body. The fence can now be tilted t o the right to any de- sired position up to 45 degrees. Lock the fence in positicrn to the desired angle by gripping the dual control handle firmly, engaging the hexagon n u t and turning i t to the sight.

This fence has a positive stop a t the 0 degree posi- tion or wher! the machined surface of the fence body is at right angles to the machined surfaces of the front and rear work tables. It also has positive stops a t the 45 degree positions on the right and left side. See FIE. 15. The 0 degree position can easily be checked 6y se t t ing t h e fence at this position and checking it with a combination scale. If the fence is not exactly at r i gh t angles to the surface of the work tables, make t h e correction by turning the special headless set scr tw in the direction required the amount neces- sary. After the setting i s correct, lock the stop screws i n position by turning the special headless set screw in the front face of the fence segment. See F~R. 16. In a similar manner the stop screws at the 45 degree position can also be adjusted. In these cases, w e supgest jointing two adjacent faces of a piece of stock. being careful to keep the first face firmly a ~ a i n s t the fence while the second face is being jointed. Check the angle between the finished faces with a carnbina-

tion scale. Make the settings in a similar manner as described above.

After making the above settings, we suggest the operator set the pointer of t he tilted angle scale.- Clamp the fence in the 0 degree position. Loosen. the hexagon head set screw in the bottom of the cross slide plate, which holds the pointer rod in posi- tion, using the '/s inch hexagon wrench and setting the pointer to the 0 degree position of the tilt angle scaIe. See Pig. 14. Tighten the set screw in the bottom of the cross slide plate to secure the pointer in position. The pointer will then indicate the correct angle to which the fence i s tilted. so the operator can easily read directly off the graduated scale.

When jointing thin stock oftentimes referred to as surfacing or planing the surface of stock, we sug- gest the operator attach a 5 inch wide auxiliary wood face plate to the cast iron fence body. Use three flat head machine screws through the recess holes in the face plate and t he holes in t he fence body. Place a nut on each screw projecting from the right side of the cast iron fence bady.

Cutter Heod Repaits W h e n the knives of the cutter head cannot be

properly sharpened to produce a nice smooth, clean cut by the methods as described above. they must be ground to a new bevel edge. I n this case, or when the b e a r i n ~ s of the cutter head need replacement, remove the entire cutter head with bearings and hous- ings from the base casting and return it to the fac- tory. To remove the cutter head with bearings and housings from the base casting back out the hexagon head cap screw from each bearing housing which i s fastened to the machined curved seats of the base casting.

HEAD

Fig. 1 7 We suggest the customer purchase a n additional

cutter head assembly complete w i t h bearings and honsing's. The extra cutter head assembly is neces- sary to keep the machine in operation when the orig- inal cutter head is sent back to the factory for re- pairs. such as, replacement of bearings, grinding and resetting the knives. The additional cost of an extra cutter head assembly is justified when maximum production of high quality type work is required. W h e n mounting the cutter head to the base cast-

ing of the jointer. be sure the machined curved seats of the base casting are cleaned free from any dust, dirt, or grease to obtain a good tight fit.

After considerable use, the knives will b ~ o m e dull and it will not be possible to do accurate work. Unlrss

3adly damaged by running into metal or other hard material, they may be sharpened as follows:

Whetting Knives Use a fine c.atborundum stone; cover it partly with

paper as indicated in Fig.17, to avoid marking the table. Lay the stonc on the front table, tower the table and turn the cutter head forward until the stone lies flat on the bevel of the knife, as shown. Hold the cutter head from turning, and whet t l ~ c bevelIed edge of the knife. stroking lengthwise by sliding the stone back and forth across the tabIt. Do the same amount of whetting on each of the three blades.

Jointing Knives

Knives may also be sharpened and brought to a true cutting circle by "jointing" their edges white the cutter head is revolving. T o do this, place the car- borundum stonc on the tear table as shown below

i

Safety Knife Guard and Tensioning Mechanism The front knife guard with pivot pin and tensioning

mechanism is attached to the front table casting. The safety knife guard has a pivot pin cast in it which makes it an integral part of the guard. The pivot pin is placed in a hole in the front tabIe cast in^. The tensioninq mechanism is attached beneath the front work table directly below the knife blade guard. See F ~ E . 3.

To obtain the desired amount of tension on the knife blade ~ u a t d . turn the fluted hand knob of the - tension in^ mechanism to the r i ~ h t the amount neces- sary, working from the left side of the machine: place the pivot pin through the small hole in the table castinq, o u s h i n ~ it downward until its slotted end encages the torsional spring of the tensioning mechanism.

This guard will- give the operator maximum pro- tection at all times and wilt prevent the hands from accidentally striking the revolving knives of the cutter head while i t is in operation. For this reason we suEgest the operator purchase a n additional safety blade ~ u a r d and tension in^ mechanism for the rcar table. This will ~ i v e additionaI protection to the operator since the revolvinc knives of the cutter head behind the ~ u i d e fence will be entirely covered. Always use the front knife blade guard whenever possible.

An additional feature of this mechanism enables the operator t o mount the knife guard after obtain- ing the correct tension and lock i t in place to prevent unauthorized removal by engaging a padlock through a hole in the pivot pin that projects through the ten- sioning. mechanism.

Be sure that the rear table is at the highest point of the cutting circle. Start the machine and move the stonc forward until it projects over the knives; then move it across the table so that the knives are jointed their entire length. Keep the stone flat on the table. I f the stone does not touch the knives at all points, lower the rear table one or two thousandths of an inch and repeat. When this operation is carefully done, the knives will cut very smoothly.

Safety Rules

1. Always keep your hands on top of the work.

2. Always hold the work firmly on the table or against the fence.

3. Always turn the concave side of stock toward the table and cut with the grain, not against it.

4. Never run a piece of stock shorter than 12 inches across the jointer.

5. Do no t operate the jointer unless the guard is in place and working.

6. Do not USE the iointer when the knives are dull.

7. Never attempt to run a plece of wood across the jointer until the machine is running at full speed.

8. Set the fence at right angles ta the table. Test with a square.
