    When itget.s down to it, it '. not what the

    chisel l o o ks like, it'. the ,er.l tip, the

    cutting edge, that does the work. Above

    all, the chisels must be sharp. All of the

    chisel work on dovetails is done with the

    chisel SCt across the grain and chopping

    straight down. The mill way to do this

    However, in

    a n

    fairness, there is one

    WESTE., liNCH JAPAHm

    Mist DOVETAil CHISEL

    other factor that may influenee the

    decision ofwhich chisel

    to

    use. Most bench

    chisels (including paring chisels and butt

    chisels) have beveled edges. (This refers to

    the bevel aIongthe length of the 'back: not

    the beveled cutting edge.) This beveled

    edge makes it much easier to chop out the

    waste inthe angled corners of L b o dovetail.

    ha s

    a yen

    for the Japanese dovetail saw (called a

    d oz uk i), (L in Fig. I) . The one w e have was

    purchased at a local store, but several

    catalogs

    are

    thin steel (ours is 0.12 thick. Orabout the

    thickness of 2 pages of IVoodsm ith ). The

    teeth ar e long and narrow (about 4 teeth

    per inch). The major difference is that all

    Japanese

    cut on the pull stroke (the

    to the push stroke on all Wpstern

    This actually makes a lot of sense. M the

    dovetails, and likens the felt-tip pen to the

    traditional Japanese practice of using A

    quiU and ink to mark their cuts.)

    OVETIL S WS

    After you've layed out an d marked the

    dovetail, you need onl~' two tools to cut

    them: a

    s aw a n d a c his el

    The choice of the

    type of

    saw and

    chisel is, once again,

    fraught with debate. But what it boils

    down to is a matter ofpersonal preference.

    DOVETAIl. S AwS . There areseveral types

    of saws designed for cutting dovetails.

    Although they differ in appearance, they

    do (or should) have a few things in

    common ,

    t irst, a high

    number

    of teeth per ineh

    usually these saws have

    16

    to

    21

    teeth per

    ineh ( the more the better). Second.

    a

    fine

    or narrow set to the teeth. The finer the

    set.

    the

    less

    chance of skipping or hopping

    as the Initial cut is m a d e . Third, the saw

    blade itself is made of lilin-puge

    steel.

    T h is allows for a narrow kerf (if the weth

    are

    set properly). And fourth. since the

    blade is thin, these saws have a 'back' of

    thicker metal to keep the blade rigid

    (hence the name, back saw).

    With these things in common. the only

    real dill'erence between one dovetail

    s a w

    and another is the handJe. A Tyz(1ck dove

    tail ..aw , for example. has a normal sa w

    handle grip. The Gent's saw (presumably

    for gentlemen) has a turned handle (much

    like

    a

    chisel) that extends straight back

    from the saw's 'back,' A n d finally, there's

    the Japanese dovetail

    s aw

    with a long

    handle

    extending

    at

    a

    slight downward

    angle from the saw's back (surprisingly

    s i m i l a r to the Cent's ssw.)

    T\Z oACKDO\ETA II . SAW . So , what s aw d~

    you use? My favorite

    saw

    for cutting

    dovetails is the 'llI:ad< dovetail sa w ill

    the box is meant to

    support weight from the outside

    often neglectedl step L to true up the

    b oa rd s y ou ll

    be

    working with. I rip the

    boards to width, makinll sure both edges

    are ripped square, (The edges can be

    smoothed on ajoint.,r or with a hand plane,

    but usually wait until after the dovetails

    are cut for the 6nal smoothing.)

    Next, both faces of the boards should

    be

    planed or sanded to remove any defects

    (such as ripples' leit ~surface planer).

    or to remove any cup or twist in the

    boards. Also, make sure the thickne. ...s

    (particularly at the ends of lhe boards) is

    equal from one ooge to the other.

    In

    other words. the boards should be flat

    and smooth - to the point that all they

    need is little finish sanding. This w ill

    ensure things don't get goofed up durin :

    the layout phase.

    2.( I.IT1 OLeNGTIf.

    Now

    the boards can

    be

    cut to length.

    However ,

    the final length of

    each board depends in part on step three

    (which deals with marking the base line. or

    shoulders of the joint). But (or noll', let's

    assume the boards ar e CUtto length tor a

    box. The key thing here is to make sure the

    ends of the board. are cuI square with the

    edges.

    If neither the inside or outside dimen

    sions of the box is absolutely critical. then

    the boards can be cut to length without

    much concern ifthe actual final dimensions

    vary a little.

    However, in drawer work, especially

    when the drawer mU ,,1 fit in R spec if ic

    opening, the procedure followed in Step

    3

    mus t be taken into consideration first.

    fall ofthis is toomuch, lhe real point of

    Step

    2

    is

    to

    make sure the end$ofaIJ boards

    are square with the edges.

    3. MARK TH: SIIOt'WERS.The boards art

    true, the end, are cut olf square. Now all

    that remains smarking the base line (the

    shoulders) of the pins and tails. This base

    line is actually the bottom of the cut on

    both pieces, and in effect dictates the final

    dimensions of the box.

    The base Unealso dictates the amount of

    work you must do during the final cleaning

    up stage. Without getting boggoo down in

    to o much detail, you have three choices.

    The base lines can be marked exactly at

    Once

    you've collected the tools to do the

    job, it's time to start laying OUIthe cuts.

    There are three basic variations on the

    dov~tailjoint: througb dovetail. half-blind,

    and mitered (or fullblind).

    Although much of the process is very

    similar fu r l l three variauons, we're limit...

    in) thi~ article to Ihrough dovetails. Half

    blind dovet.ails (which are used mainly

    in

    drawer construction) will

    be

    covered inthe

    next issue. And mitered dovetailfl WOIl'tbe

    covered at

    because

    tbey

    ba

    ve extremely

    limited application (and they're really kind

    of a waste of time).

    THROUGH UOVETAU.s. The method des..

    eribed here for cutting through dovetails

    may

    not

    be

    the best. It's certainly not the

    fastest. But it is satisfying' work .. done

    ,,~th hand tools.

    through don tailjoint consists of two

    halves: the pin> and the tails. The worst

    parlabout laying out

    a dovetait

    is gcttinl

    clear picture in your mind of what

    these

    tw o halves look like and how they fit

    together. This just takes a little getting

    used to.

    When viewed from the faee

    sides

    of Ihe

    boards, the usOfthe dovetail the board

    on the right in the photo) lookjusllike the

    rectangular pins of. box joint. h toils

    (the board on the left in the photo) looklike

    a dove's tail (hence the name of the joint).

    Just to keep you on your toes.

    when

    v iewed from the ends of the boards the

    pins look like tails. and the tails look like

    pins. But this confusion will clear up aner

    you've cut one or two dovetail joints.

    IRE TION OF STRENGTH

    Now the question arises: Which board get.

    pins,

    and which board gets lhe t.aiL.?

    GENERAL LAYOUT

    By Ihi. time you'r(>probHblygelting titt ' ;.AfWr all the cuts

    have been made, hold a try square along

    each CUt line (both front and back) and

    make sure the edges of Ihe pins are per

    pendicular to the end of the board.

    I( the pins are not straight, I mark a

    slightly heavier line (as illFig. 4) and cor

    reet them by paring down with a fairly

    ide sharp chisel, Fig. 12.

    Youcan also cheek the pins by eye, sight-

    ing down the lengtb

    the board to see if

    the pins are all straight and parallel.

    Next comes the tails.

    The saw should be angled (about-lS'l

    so

    your rll'lltcuts will be on both the face and

    end ofthe board. Now. relax your hand and

    make the first two strokes.

    The kerf should be skimming along the

    pencil line. Since the teeth o( a dovetail

    saw have very

    narrow

    set, these beginning

    tWOstrokes will hold the

    saw

    inposition for

    the rest of the cut. I(you're not on the line

    to begin with. any attempts to force the cut

    or make adjustments in mid-stream

    will

    cause the saw to bind and ;U lead to all

    sons of problems.

    After

    a

    few strokes the

    saw

    should be

    about /s of the way down the face and

    o/. s across the end. see Fig. 6 . Now you

    can level out the saw so it starts cutting

    through to the back of the board. Continue

    sawing until the Wjust barely touche.

    the ba.se Iines, (All the time your hand

    should be very relaxed.just barely holding

    the saw. Relaxed. yet eoncemraring.)

    If you're 9;oingto :oofon these cuts, it's

    best

    to

    goof 01 1 the waste side of the line.

    That is, the saw should leave a little extra

    woo d

    between the kerf and the pencil nne.

    f there is a problem, let it go for now. It

    can be corrected Iatez)

    CHOPPING OUT TH( WAST(

    After making a U of the saw euts, you can

    start chopping otltthe waste. One way to

    do this is to hold the chisel absolutely per

    pendicular

    to

    the board. and chop straight

    Mostof the preliminary work (or laying out

    dovetail joint has been covered in the

    article on the p revious tWOpages. Once

    all

    of these details have been worked out on

    paper, it's nowjust a matwroflransferrmg

    the~e measurements to the end of the

    board. and start cutting the pins.

    Before you start marking. however. the

    first three

    steps rernam

    th ,

    same.

    That is,

    I

    rrue the boards yc,ur working with,

    2

    CUtthem to length (making sure the ends

    are square to the edges), and

    3), mark

    the

    b as e lines .

    Por the

    pins,

    the base

    lines

    need

    only be marked on the two faees of the

    board,

    see

    Fig.

    LAYINGOUT THE PINS

    To mark the position of the pins. clamp

    the board in

    a

    ice \\;th the

    -orr-

    SIde of

    the board facing me. Since I've already

    worked out lhe size and position oflh. pins

    on paper its

    now

    jus t a matter

    oftransfer

    ing the marks with the aid of. 12 steel

    ruler, Fig. 2. (This is where it's helpful to

    use a chisel togauge the width of'the pins.)

    MAf; from get

    ting confused (whicb often happens)

    mark an

    X

    on the waste seetions be

    tween the pins.

    SAWING THE PINS

    Nowyou're ready lo take saw nhand. Slop

    everything. Relax your hand, your arm,

    your shoulders and especially your mind.

    The way toget the best results is to relax,

    yet concentrate on what you're doing.

    Place lbe saw on one of the lines.

    The placement o( the saw and the

    first

    two gentle strokes will detennine the suc

    cess of the rest of the cut. Look closely at

    the teeth of the saw. Because the teeth

    have 'set' (that is, alternate teeth are bent

    to the right and lelt.), you'll only see half of

    the teeth. Place one tooth right up against,

    tbe waste side of the pencil line. That is, so

    the kerf will be on the waste side (the X

    side) of the line, see Fig. S.

    One of the nicest things about woodwork

    ing is having the chance to make your own

    tools. Granted, it's a wee bit difficult to

    build something like a table saw out of

    scrap> laying around the shop, but every

    once in a while thert>is a U>'efullit1legad

    ge t

    you ea n

    make.

    One of the things I've always wanted to

    make

    w a s

    my own marking gauge. 1 kept

    LOyingwith the idea,

    but

    there were two

    problems r couldn't find a solution for.

    to

    hold the

    arm

    securely in

    after it

    was

    set, This is usually done with n fancy brass

    that

    goes

    through

    a

    threaded

    hole in the wooden body. (There a re to o ls

    When I discovered rosan inserts 'some

    had LOdowas screw the

    rosan

    old thumb screw to hold the arm in lace.

    Rut the thumb screw dented the wood,

    leaving little holes along the arm that C U-

    se d problems. So . next needed a fancy

    brass shoe like on the 'stcre-beughi' mark

    idn't have o ne o f these

    that

    was

    the

    answer for my

    penny-

    pinching marking' gauge. (On Lhe deluxe

    model I use a dime.)

    Getting this all put together is shown in

    the drawings at right. Since r had to eoun

    terbore a hole for the shoe tpenny), I made

    the body by cutting a dado insome

    Y

    stock

    (the one shown is made of cherry).

    Arter getting the two halves (Fil '. I), I

    drilled a 0 hole ~.' deep (for the penny),

    and followed ith a . hole for the rosan

    insert. Then 1 glued the two halves

    together so the dadoes formed a mortise.

    Next ipped a piece fo r the arm so

    SOLID WOOD BOTTOM

    Since dovetails are usually reserved for

    drawer. (and fumitu re) of ra ther high

    quality, you may Want to

    make

    a solid

    wood bottom (instead of USingplywood).

    The problem with solid wood is that it's

    going to move (expand/contract with

    s e as on a l c h an g es in humidity). If a solid

    wood bottom

    were

    glued

    into

    a

    rabbet,

    it

    wouldn't be free to move. an d sooner or

    later it would split. So it must be mounted

    with the

    stopped

    groove method.

    The solid wood bottom ca n be ,luedI of

    slightly thicker wood lhan the groove.

    Then the edges

    ar e

    chamfered

    (jUSt

    like

    a

    raised-panel in

    a

    door), or rabbeted toform

    a tongue to lit the groove.

    The primary considerution, however, is

    l he d i reeucn

    oflhe grain,

    Fig 4

    TIle grain

    m u st ru n a cro ss the width of the drawer.

    That is.

    so

    the end grain it;mounted in

    th e

    drawer sides.

    h front edge of the bottom can be

    glued into tbe groove inthe drawer front to

    hold it

    in

    place. However. the edges in the

    drawer sides must be free to move (no glue

    is used

    Also

    the back sbould be trimmed

    SO it rests on top of the solid

    wood

    boUom.

    This allows the wood to move freely.
