Small loosepieces ofwood or other objectsthat contacta

spinning workplececan be propelledat very highspeed.

Thiscan be avoided by keeping the latheclean.

Never turn the lathe ON before clearing the bed, head and

tailstock ot all tools, wood scraps, etc., except the werkpiece

and related support devicse for the operation planned.

Never place your lace or body in line with the chuck or

faceplate.

• Never plane your fingers or hande in path ut cutting tools.

• Never roach in back of the workpiece with either hand to

support the piece, remove wood scraps, or lor any other

mason, Avoid awkward aperetions and hand positions

where a sudden slip could cause fingers or hand to move

into a spinning workplece.

• Shut the lathe OFF and disconnect power source when

removing the faneplste, changing the center, adding or

removing an a,z<itiary device, or making adjustments.

• Turn _ lock switch to =off" and remove _ when tool is

not in use.

• If the workplece splits or is damaged in any way, turn lathe

OFF and remove the workpiece Imm the holders. Discard

damaged workpiece and start with a new piece of wood.

• Use extra care when turning wood with twisted grain or

wood that is twisted or bowed -- it may cut unevenly or

wobble excessively.

• When hand-sanding fsceplate or between-ceeters mount-

ed werkpieces, complete all sanding BEFORE removing

the workplece from the lathe.

Never run the spindle in the wrong directiee. The cutting

tool could be pulled from your hands. The workpiece

should always turn towards the operator.

For spindle tur_ng, ALWAYS paslion the tool rest above the

centedine of the workplece and spindle (sppreKin'kately'_").

Use the ddll chuck accessory in the tall efock only. Do not

mount any drill bit that extends mere than 6" beyond chuck

jaws.

SPINDLE TURNING

If you have never done any amountot wood turning,we sug-

• Selecta plese ot wood 2" x 2" x 12".

• Drawdiagonallines on each end to locatethe centers.

Diagonal Unes on

Both Ends

• Observe the speed chart (see page 14). For example, a 2"

square turning uP to 18" long should run at 1100 RPM for

"roughing'. Rotate the wood by hand to make sum that the

corners do not strike tim tool rest and verify that the index-

ing pin is not engaged.

Rgure 11

• On one end, make a saw cut epprosJn'_ely 'A," deep on

each diagonal line,This isfor the spor o_nter,

• The other end uses the bearing center. Place the point ot

the bearing center on the wood where the diagonal lines

cross`

• Drivethe bearingcenter intothe wood.Use a wooden mat-

let or a plastic hammer, butput a piece ofwood onthe end

ofthe bearing centerto prctect itfrom harm.

OUTBOARD TURNING

This technique mat_s it possible to do jobs on this machine

that are too large to mount conventionally. It is straight forward

laospiste turning, except, because of the work size, caution

must be talon and speeds must be restricted to minimums. If

you anticipate doing outboard turning you must use a bowl

turning rest (see Recommended Accessories, page 27). The

bowl turning rest is attached to the lathe bed. See Figure 16,

page 8.

CAUTION: Do not try topush this support when cutting.Do

nottry to mountwork so large that the motor must strain to

turnit. If youwish toexperimentwith thistechnique,do so

with softwoods.Let the heavier, herder wood come later.

USING WOODWORKING CHISELS

Many operationsrequirethat the cuttingchiselsbe used for

scraping,but scraping chiselsare practicallynever used for

cutting.Scrapingdullsa chiselmuch faster, especiallythe

razorsharp cuttingchisels.

Cuttingisfaster than scrapingandproduces asmootherfinish

whichrequiresless sanding.However,it isfar more difficultto

master.Scraping, on the other hand, islar morepreciseand

easier to control.

SELECTION OF CHISELS

These are the mostused.They are commonlysharpened

to a razoredge by honingon both sides.

• The scrapingchiselsare the flat n_e, roundnose and

Cutting and Scraping

• To cut, the chisel is held so that the sharp edge actually

digs into the revolving work to peel otf shavings.

• To scrape, the chisel is held at a dgN angle to the work sur-

lace. This tool remcves fine particles instead of shavings.

WhenYou Can Cut andWhanYou Must Scrape

In general, a cueingactionis used for the majorityofspindle

turningoperations while taceplateturningisusuallyaccom-

plishedby the scrapingmethod.When a combination

approach isto be used,the operator will haveto judge,by the

feel ot the work,when tostopcuttingand start scraping.

Never try to cutwhen itbecomesdifficultto holdthe chisel

againstthe mughnese ofthe wood grain.

Haw to PosltlonTool Rest for Clrcurnterenoa Cutting

When cutting,the object isto piercethe outer skinof woodto

a certain desireddepthand thento holdthe chiselsteady

with the bevel edge parallelto the workcimundemnceso that

itwillpeel oft ashaving at this desireddepth,

• The only sure methodof holdingthe chiselsteady is to

mat the b_vel against the work(Figure 21A).When the toni

mat isat the proper height, the chiselcan be held withthe

bevelpressed againstthe work, and the tool restwill act

as a fulcrum tosupport the chiselagainstthe downward

forceof the revolvingwork.

• If the restis placed too low, sothat thechisel isheld with

the bevel out fromthe work (Figure21B), the cuttingedge

will continueto dig deeper intothe work.It will dig inuntil

the "bite" becomes so deep thatyour hands have difficuly

holdingthe chisel- then the improperlysupportedchisel

will beginto bounce or chatter against the workplace.

• ffthe rest is placed ton low,the chiselmustbe held

extremely high topositionthe bevel against the work

(Figure 21C).Then the rest losesrno_ of itsvalue as a ful-

crumand the downwardforce ofthe revolvingworkplecu

How to PoalUon Chisel and Rest for Diameter Scraping

When scraping on the diameter, that portico of sudase tothe

right of center is moving upward (Figure 23A). if a chisel is

placed in this area, it will simply be carrisd up oft the rest and

out of your hands.

• All diameter approach aparations must be done st the k_t

Itwill be notedthatwhen a chiselis abovethe workpieoscen-

USING THE SKEW

• Two skews, the '/zand 1" sizes, am all that are needed for

general use. Other sizes are avallsble,

This tool isnearly always used to ma_ fbished cuts, to cut vees

and beads, and to square shoulders. Properly used, i produces

the best finish that can he obtained with a chisel. It is not recom-

mended for scraping because the edge tends to dul more qalddy.

For finish cutting, the skew is held with the cutting edge

considerably in advance of the handle, bevel side down.

Keep the base ol the bevel against the work. It is good

practice is to place the skew well o_,er the wod_, pull it back

until the edge begins to cut, then owing the handle into

position to advance the cut.

Both the toe and the heal d the slew can be used for taking light

cuts, but do not penetrate the wood too deeply without cutting

_s.There is danger ol burring the tip of the tooL

Rgure25

USING THE PARTING TOOL

The pwting tool has just one prrnaw purpose: to cut into the

workpiece as deeply as desired, or all the way through to make a

aJt-off, It is,the_ore, a very narrow tool ak" wide) and shaped to

cut its own clearance so that the edge will not he burned.When

used for scraping, however, the parting tool should be backed off

regularly to prevent overheating.

Unli_ the gouge and slew, the parting tool is seldom hatd with

the beval against the work. Since the _nt of stock removal is

small, a support for the bevel is not neoes_y.

The tool is simply led into the work at an angle (for cutting), or

pointed at the workpleoe center (Ior scraping). It can be held eas-

ily in one hand.

USINGTHE SCRAPING CHISELS

• A '/l' wide spear point chisel, a '/z"wide round nose chisel,

and a 1" wide flat nose chisel complete the list of tools

ordinarily used by crattsmen and hobbyists.

Each of these scraping chisels can be purchased in various

other sizes Ior special purposes. All am very useful for diame-

ter scraping operations and for circumference scraping when

cutting methods cannot be employed.

• The spear point is used for line soraping and delicate oper-

ations such as the forming of beads, parallel grooves and

shallow vses.

• Edges and bowl contours can be rounded with the round

nose chisel.

• Any flat sudaca can be scrapedwiththe flat nose chisel.

USING SHAPER OR MOULDING KNIVES

• An old chisel can be made to serve as a holder for shaper

or moulding knives.

Such knives male it possible to scrape many interesting

shades into the workpiece surface using _ or two operations

instead of the many operations required wih standard chisels.

it is generally not practical to use cutting mathods with spedal

shape tools. Scraping methods should he used instead.

• The holder should provide a shoulder against which the

butt end of lhe krlite can be firmly seated,The knife must

be securely mounted, either by means nt a screw threaded

into the holder, or by compressing it between two prongs

bolted together.

USING A BLOCK PLANE

Clear, glass.smooth linishes (especially on softwoods) can be

obtained by using a block plane sat to take a fine shaving.

• The tool rest should be raised up apprasimately to the top

of the workplece - and the plane should be horizontal, but

turned slightly in the direction of travel so that it will tale a

shearing cut,

• Two tool rests, one in front and the other behind the work, can

be used to advantage in p_itioning the plane so as to eKaotly

limit the dep(h of cut (and fi_ size of the wod_piece).

Rgum 2g

USING WOOD RASPS AND FILES

• A wood rasp will remove stock quickly when held against

the revolving workpisce. Cam should be talen to support

the rasp firmly against the tool rest. An improperly held

rasp, when used on a rough sudaoe, can kick back and

cause operalor injury,

• The rasp will leave avery rough finish.

• Finer finishes (similar to those produced by scraping) can

be obtained by using files in the same manner. Various

types of files can be used for shaping vees, beads, caves,

eLc. if pressed too hard into the wood, some files can burn

the workpiece.

• Keep the file clean to keep it cutting uniformly. Files work

best on hardwoods.

MAKING STANDARD CUTS

THE ROUGHING-OFF CUT

Reducing a square or odd shaped workDieos down to a cylin-

der of approximate size for finish turning is called "roughing-

off". Faosplste turnings and large diameter spindles should

first be partly reduced by sawing, but small spindles are easily

turned down entirely with the large (',_') gouge.

RO_o

• Start the firstcutabout2" fromtail stock end - then runit

towardthe tailatnekand off the end of theworkpieos.

• Nsst, startanothercut 2" nearerthe headstock- and run it

back towardsthetaiistnek,to mergewith the firstcUt.

• Continuecuttingin thismanner until2 to 4" from the head-

stock is lettuncut.Reverse the directionof tooltraveland

workone or twocUtsin successiontoward the headstock

and(_f thisend of the workpieee.

• Never start a cUtdirectlyst the end - ifthe chisel catches

the end, it willdamage the wod_leco.

• Never take longcutswhile cornersremain onthe work,as

this tends totear longdivers fromthe corners,

• The first series of cuts shouldnottieton deep. It isbetter

topartiallyreduce the workto a cylinderall along its

length.Afterthat, start a second series of cutsto complete

reducingitto a cylinder.

* Once a cylinder has been Iormed,step latheup to next

fasterspeed. Furtherreductionsin size can nowhe

accomplishedby cuttingas deeply as desired at anyspot

along thework.Atthis stage, longcutscan be madefrom

the centerto eitherend.

• Generally,roughingoff iscontinueduntilthe cylinder is

approKimately %"lan:jerthan the desired finished size.

• Roundness can be tested by laying the gouge on top of

the work - it will not ride up and down when cylinder is

perfectly found.

• One method is to mount addll in the tailstock The work-

piece is held and revolvedby the headstock. If the ddll has

a Morse taper shank, it can be mounted directly in some

tail stock rams. OthenNise, it can be mounted in a chuck fit-

ted with the proper type shank.

• Another method of holding the drill is to mount it in the

headstock using a 4-jaw (metal-lsthe) chuck or a Jacobs

chuck When this method is employed, there is no accurate

PREPARING A PLUG CHUCK

A plug chuck is an at_iliaq/wood chuck mounted onto a faos-

plste. The chuck can be any size diameter, but it should be

about 1%" thick for stability. The wood chuck should be pro-

vided with a '_;or _,_"hole in the center for receiving a tenon

turned st the end of the workpieos.

Rgure 57

Once made, suchchucksare permanent usefulf_tures for

turningballs,goblets,etc. In use,the wood stock for tuming is

turnedbetween centersto producea tenon at one end which

RECHUCKING

Rechucidng is the general term used to descnbe any addition-

al work mounting that is necessary to complete a turning pro-

jeot.The method of working ojlinders, and the use of a plug

chuck as already described are typical examples. Another

good eKample is the rechuddng of a bowl,

• The work is mounted on a wood bac_dng block secured to

the large faceplate and it is turned in the usual manner. All

sudases ere cut e_cept the back side (which is against the

mounting block), The work is then removed from the

mounting block.

• An aL_itiary chuck of softwood is now made in the same

manner that the cylinder chuck is made. This chuck must

have a turned recess properly sized to accommodate the

rim of the bowl in a tight press fit.

• When the bowl is mounted in this chuck, the bottom can

be cleaned off and slightly recessed to complete the

desired contours.

Rgure 60

TURNING A RING

One method of turning a ring requires a spindle chuck,

• The work stock is first mounted to a bacldng block held by

the large taceplste and is turned to shape on the outer

side. The inside diameter of the ring is also shaped - all

the way through to the bacldng block.

• The work is then removed from the backing block.

• A spindle chuck is now prepared so that it will be a tight

press to fit inside the ring.The ring is raversed and mount-

ed on this chuck. With the ring mounted, the remaining

contours can be turned to shape.

Rgure el

Another method of turning a ring makes use of a recessed

chuck,

• The work stock is mounted ne a sorew center and oce heit of

the ring is |ormed, but the ring is not cut away from is center.

• The stock isthen removed, and a mcesssd chuck - mounted

on the large facaplete - is prepared to receive the ring in a

tight press tit.

• Alter being shucked, the remaining face of the ring can be

turned to the proper contour, thus cutting away the center

portion.

• In work of this type, take constant measumrneats or, better

yet, use a template to guard against over or under cutting.

TURNING BALLS

• Wooden balls of large size are lirst roughly turned between

centers, using standard procedures.

• Smaller balls can be mounted as taseplates on the small

facoplate or screw center.

• Unes drawn to indicate the center and ends of the ball

shape are helpful in plotting the curve.

• A template should always be used for accurate visual

observation of the work progress.

• When usingthe shallowchuck, awsed blockis fittedtothe

tailstock sothat the ball can revolveuponit. This block

shouldbe lubricatedwith bees'vaxor grease.

TURNED BOXES

Turned boKes irlvoivedeep reses_ng together with a special sys-

tem ofworking the lid and body of the boKtogether as one unit.

• The inside of the lid is turned first.

• Next, the inside of the body is turned. A care/ul check must

be made when turning the lip of the body podiorl so that

the lid will be a tight press fit.

• The lid isthen pressed onto the body and the outer circumfer-

ence and face of the lid, together with the outer drcumference

of the body, are turned all at one tk_e.This insures accurate

matching of the two pieces.

• After the work is complete, the tight fit nt the lid can be

relieved by sanding the lip of the body.

SEGMENTED TURNINGS

Segrnehted bowls and boKes are exceptionally attractive- and

this method of preparing wood stock is more economical than

the use d a large piece of stock. Far some typos of work, seg-

meriting isthe only practical method because a block (f obtain-

able) would be so laKje that it would be very lilely to warp.

• The bowl illuetrsted in Figure 66 requires 12 segrnont pieses

lot"the sides. Bowls can also be worked with 6 or 8 pieces.

• To make the 12-piece bowl, a board about _/,x 3 x 30" is

cut into pieces about 2'/," long, the saw blade being tilted

15= and the board being turned altemetely lace up and

face down to make the successive cuts.

• These 12 pieces am glued together and clamped by wrap-

ping the assembly with wire (or equivalent).

• When dry, the rim thus Iormed is glued to a temporary cir-

cular b ad,,,ingwhich is mounted on a large laceplate.

Rgure e6

• A"/,"deep recess of the largestpossiblediameteris

turned inthe open end of the rim.

• The rim is removedfrom the lethe and stock forthe bottom

is mountedin its place on asecond laceplete. This is

turnedto size - and a rim about'/," deepis turnedto

exactlyfitthe recess prepared in the rim.

• The dm isthen fittedoverthe bottomandglued, making a

drumshepe with a faceplate st each end,

• This drum iscut cee'plately intwo at a pointabout =,_"

TURNING PLASTICS

TYPES OF PLASTICS

There are twogeneral groupsof plastics.The firstincludesall

phenolplasticsmnided underheat and pressure.Bakeliteand

Formicaare examples. In the second am all catalystsetting

plasticsef variousbases sold undersuchtrade names as

Lucite,Cetalin, Cast Bakelite,Marbiette,Tenite andTraltord.

Thosein the secondgroupare mostgenerally usedforcreft

work.They are easy to turn,being a Iffiie harderthanwood,

butmuch salter than are/of the softmetals.

MOUNTING THE WORK

The most usefulmountingdeviceisthe 4-jaw (metallathe)

chuck.When thisis not available,cylinderscan be mounted

on a slightlytaperedwooden mandrel. Reds canbe mounted

between centers, usingeither thewood mountingcenters or

metalmountingarrangements.When the spurcenter isused,

slotsshouldbe sawed acrossthe work.

USE OFWOODTURNING CHISELS

Standard wood turning chisels are excellent for turning pies-

tics by means of scraping methods.

• The tool rest should be slightly below center and the chisel

handle should be held a little higher than the cutting edge

to give a negative rake.

• Scraping tools should be kept to a minimum. A large con-

tact area, such as the lull edge of the epear-polnt chisel,

will cause chatter and probable chipping.

• Properly worked, the chip comes off in a continuous rbbon.

• In cetd weather, plastic may hecome brittle and shsold be

tempered inwarm water for about ton minutes before turning.

TURNING BALLS

Plasticballs are rough turned in the usual mannerand then

broughtto perfect roundnessby using a tubetool,The tube

shouldbe slightlyless in diameterthan the finishedsize of

the ball.It can be brass or steel, groundsquare acrossthe

POLISHING PLASTICS

Start withsanding.

• First use 150-grit drypaper to removetool marks.

• Then finishoffwith 150-grit and 400-grit papers,in succes-

sion. These abrasives should be wet.

USE OFWOOD CHUCKS FOR SANDING

Quick-acting chucks can be very useful for sanding operations

on doplicate production pads. The chuck is made slightly

cversized, and a piece oi rubber hose (for small parts) is

inserted in the recess to grip the workpieoss.
