    A1l0UT THIS ISS(;I:. \Vhenever we get

    visitors here at

    Woo milh

    one question

    that always seems to com e UI) is, ..How do

    you decide what projects to build for each

    issue?

    What we usually do is

    try

    to decide on a

    technique before we ever get to the

    projec $. For this issue, we thought it \\lIS

    time todo an article on using beneh planes.

    That naturally led

    to

    using a plane to

    smooth a table top. Which in tum led to the

    Trestle Table.

    At least that's the story I'd like to tell.

    What reaJly happened is that everybody

    kept leasing me abeut the original design

    of the Trestle Table shown inthe finsl issue

    LAMINATING THEBLANK

    The

    first step isto

    get

    a blockofwood

    larg..

    enough to turn tho goblet. I used bloeks ..

    for the goblet on the I~ft.

    To get this size block. I laminated five

    pi _ofI (''' )umberface to face. Thi.

    brings up

    the

    subject ofglue.

    f the goblet

    is

    going to be

    used

    as a

    functional piece, a

    true water-proof glue (penol-reserciuol or

    epoxy are the two most common kinds)

    must be used,

    Idecided to use a tw o-pan epoxy called

    Che Tech 1 -118,

    because it has some ma

    jor advantages over penol-resorcinol

    glues, First,

    it

    cure at

    temperatures

    down to 40', a big-advantage if

    yow .hop

    is

    in the basement or the garage. Second. it

    doesn't require

    high

    damping

    pressure

    as

    most penal-resorcinol glues do. And third.

    Once e'erything is laid OUl, go ahead

    and cut the mortises, 1 used a drill press

    and a to brad-point spur bit drill OUt

    most of the waste for the mortises. Then

    cleaned up the cheeks of each mortise with

    chisel. (See

    on each leg.

    HOLES FOR CASTERS. Finally. I drilled

    hole in the bottom of each leg for

    hard casters (No. 93Oll) . ( bought these

    casters at a local hardware store. The same

    the

    next

    step

    is to cut the two side stretchers (B) that fit

    in the middle mortises. These stretchers

    help hold the cart. together, but their main

    purpose

    is to

    preven t stuff

    from sliding

    of f

    the bouom shelf,

    First, 1 cut the two stretchers B) to

    final size - 2 ide by 18Y?long. (This

    length measurement includes the 1.long

    tenons on each end.) Then the tenons are

    cut to fit the mor tise s

    in

    the legs, The

    finishe d shoulder to shoulder length of

    these stretchers should be 16Y., see

    the cart) of all eight pieces for the shelf

    SUPI) )rtframes. I di d all of this with a y,

    corner round bit 01 1 a router table.

    ASSEMUI.Y.

    Before assembling the cart.

    I fini hetl sanded all pieces.

    It S

    a lot

    easier to do It now than afLer assembly.)

    Then to assemble the

    cart,

    I glued-up the

    shelf support frames (making sure they

    were na t and square Ill they were clamped

    together). Then I glued these assembled

    frames and the side stretchers into the

    legs. This completes the basic cart .

    THEWORKING SURfACES

    Now that the cart iscomplete, all you need

    are the three work surfaces- the top and

    leaves, and the two shelves. made all

    thr ee of these SUlfates by gluing up strips

    of

    4/ 4

    stock ( Y.

    thick

    to give them

    a

    butcher block appearance.

    Note: 1 did not us e dowels or splines

    when gluing-up

    these th ree

    planks.

    Just

    a straight edge-to-edge gluing and clamp

    ing prevides enough strength.

    THESrn)LI'F,s.

    The bottom

    shelf F)

    and

    the adjustable shelf

    are the easiest

    just out 24 su-ips 10/,, wide,

    6

    long.

    (This length allows a little

    Waste

    at the

    ends of these planks. They're trimmed to

    final length later.)

    Glue 12of these strips tngether to form

    the bottom shelf, and th e

    remaining

    12

    strips

    to form the adjustable shelf. Then

    set them aside to dry overnight.

    THE TOP ,,- 0 l.EAI'ES. To iorm the top

    and the two leaves H . cut 12more strips

    1%'wide,

    but this time

    5O~'

    long. Then

    edge glue these 12 strips to form one long

    plank. Once again this rough length is

    more than is needed.

    In effect. you're gluing up all three

    piece. (top and two leaves) at the same

    time so there will be 3 continuous grain

    pattern across the enure surface when the

    leaves are up.

    After the glue bas dried (overnight) on

    all three planks, plane them Oat on both

    sides (see page 20 for more information on

    planing large surfaces).

    TRill TOSIZE. Next. the bottom shelf and

    the adjustable shelf can

    be

    trimmed to final

    width

    19V, ).

    To cut them to final length

    (25y,;). I used the panel cutting jig shown

    in

    l V o o d smi t i l No. 22.

    The plank for the toll and two leave. is

    also trimmed to 1 9 y ; wide, but then it's

    cut into three pieces. First cut.

    5V

    section out of the middle of the plank, see

    Fig. 4.

    Next. cut the two 12 -long leaves from

    the two 'waste pieces that remain. These

    leaves are trimmed down to a width of

    16Yo (which is

    NOCAPS

    As mentioned above, the end caps (or

    bread-board

    ends) are

    a

    traditional fealul'e

    on trestle tables. but they're a real hassle

    to mount. The problem

    ha s

    to do with the

    direction of grain

    The grain of the end cap runs at a right

    angle to the

    grain

    of the table top. Thus.

    the table top

    will

    move (in width) much

    more than the end caps (in length).

    \\'hat this boils

    down

    to is that the end

    caps can not be glued in place. They must

    be mounted to allow for the movement of

    th. lOp. There are several methods for

    mounting end caps to allow for this move

    ment - some rood . some not so good.

    But the one we're showing here is one of

    the best ways weve come lip with to pro

    vide the strength needed at the

    end or

    the

    table. The mounting procedure

    used

    is a

    combination ofsleued serews and a tongue

    and gTOO\'ejoint. This is a rather typical

    approach. But

    T e e l

    earneup with the idea of

    adding the end strips C) to add strength.

    The real purpose of these strips is to

    serve as extensions of the end caps under

    the table. refer to Fig. 7. Since the grain of

    These end strips are also

    ripped

    2

    wide. bUI

    the

    length

    should

    be about

    le than the distance between the side

    thicknesser

    strips, Pig.

    3.

    This allows.

    space

    between the side strips

    to

    allow for

    movement of the table top. After the end

    S.:I.P. (..-rI()X.o r these four basic styles

    (lengths) ofbench planes, which one is the

    best? The ideal situation (if you really want

    t O

    get s e r i o u s about this b u s i n e s s of h a n d -

    planing) would be to have

    selection o(

    three sizes: smooth, jack, and either a fore

    or jointer plane.

    If you're not quite serious, the best

    choice

    (01' an all-around plane

    is

    the jack

    (jack of all trades). The jack plane in OUI

    shop gets the most use by far. In fact, it's

    used for everything from smoothing down

    relatively small p a n e l s to planing the sur

    (ace of a large table.

    PARTS OF A BENCH PLANE

    Nomatter what style (length) the plane is,

    the key to the whole thing is that it must be

    properly sharpened and adjusted before it

    THE CAP IRON

    Once the lever cap isremoved. the cap iron

    and the plane iron can be lifted out. The'.

    two irons are held together wuh a cap

    iron screw

    which

    rides in a long key-hole

    slot

    in

    the plane iron. (Thi. assembly

    is

    sometimes r e fe r red to as double

    iron. )

    THaOAl (MOUTH)

    The entire family of planes con

    sist of hundreds of individual

    l1.ylc,~.But all or these planes

    can be

    grouped

    into two basic

    categories: bench planes and

    specialty planes.

    Specilliity planes are made

    for specific p U I J X . . . .s (culling

    rabbets, or grooves, or molded

    edges). Although some

    of these

    plane. are still manufactured

    today, they are, for the most

    port, collectors' items.

    Bench planes ar e the ones

    used to smooth the'sul'l'ace nr edge of 3

    board. (Nowadays that means most of the

    work done

    by

    hand planes.) Bench planes

    are divided lnto foul'basic styles (lengths).

    The only real difference among these four

    styles is the length of the plane body (Ihe

    wi.).

    and to some extent the width of the

    plane iron (cutter). The four sryles are:

    smooth (lW,' long). jack (11), fore (18 ),

    and jointel' (2'2 ).

    Note: Although there are many varia

    uons on the length (and the width) ofeacb

    heneh plane, the lengths given above are

    the current standards for the two largest

    full-line manufacturers of steel-bodied

    bench planes: Stanle~' (U.S.) and Record

    Ridgeway (Ellglandl.

    Block planes arc SOrtof a lib-category

    of bench planes made specifically for plan

    ingendgrain. The~.re alsothemost widely

    misused of all planes, Becanse blockplanes

    arc small and relatively inexpensive,

    they re sold in almost every hardware

    store and generally th~ught t~ be

    g o o n

    The first part of the plane that

    can be removed is the lever

    cap. This isjust a lalX piece of

    nickel-plated east iron with a

    cam-action lever at the top.

    The sole purpose of this lever

    cap is to hold

    the

    next two

    pieces (the cap iron and plane

    iron) fU'IIdy in place.

    Since that's iL$sole function,

    the lever cap doesn't seem lik~

    a big deal. But this little gizmo

    is the one thing that trans

    formed the entire plane

    making industry.

    In

    18511 when

    Leonard

    Bailey patented the lir.;t cam

    action lever cal' to hold the

    plane iron in place, it replaced the old

    method of using a wooden wedge, and

    forged the way for modern steel-bodied

    planes used today.

    Enough history. From a functional

    standpoint. very little v goes wrollg

    with tbe lever c a p anything, it only

    needs 1.0 be oiled for smooth act ion.

    The lever cap is held in place with the

    lever cap screw (actually it's a machine

    bolt).

    There's no need to

    remove this

    screw; its main function is as a fulcrum for

    the lever/cam. If the movement of the

    lever/cam is too loose or too tight, JUSt

    loosen Or tighten this screw (about a quar

    ter turn usually doe. it).

    will do much (If anything. In

    fact, a brand new plane is little

    more

    than

    an intricate assern

    bly of expensive steel, In most

    ease ' it needs some work b e -

    fort' it becomes a tool.

    The fil l;t step is to dLllmantle

    the plane to get the pieces

    working the way they're sup

    posed

    to, \\'hen you start tear

    ing

    apart, what you end up

    with are the five basic pieces

    shown in ~lgure

    These five parts are: the

    lever cap, the cap iron, the

    plane iron, the frog,

    and the

    body of the plane.

    Now we're down to the f1'Og,The main

    coated with some sort of finish (either

    Then to get a really good surface,

    clamp the frog ina vise, and use a fine India

    plane iron rests on a Oat (unobstructed)

    surface.

    the brass knob is rotated in and out, the

    yoke moves the cap iron (and thus the

    plane iron) up and down, to adjust the

    depth of cut.

    Although this mechanical arrangement

    an exce.'Sive amount of slack in it, Thus,

    the knob has to be rotated an inordinate

    amount before the yoke actuaUy starts

    Although 1willadmit that l enjoy working

    with hand planes, I try to cut down on a lot

    ofunnecessary work

    by

    getting the

    surface

    of the gluedup boards as flat as possible

    before the planing ever begins.

    If I m

    gluing up several

    n a r r o w

    boards

    to form a rather large surface, I cut

    p;Ioovesonedges ofeach board for splines.

    Although splines add some strength to

    the joint, their

    C 8 purpose

    is to align the

    top face. of all the boards - to get the

    surface of lhe gluedup boards

    as

    nat

    as

    possible right from the start, This makes

    the planing operation much easier.

    However, the critical thing here is

    to

    cut

    of

    each board agaill.llt the

    fenceoflhe table saw and cut the groove on

    one edge. Then cartwheel the board (nip

    it end-for-end) so the same face is still

    against the fence, and

    o u t a

    groove on the

    other edge of the board.

    \Vben the splines are inserted in these

    say

    you should pul

    growth against old growth.

    1 can t really dispute any of these ap

    preaches, But I go about it differently.

    Two things a re important to me: I The

    grain pattern

    of the finished piece should

    b e .

    pleasing. even

    if

    it s not technically

    correct. And

    2) .

    it s more important to me

    that the boards are laid out

    SO

    the grain is

    going in the proper direction for planing,

    not

    necessarily

    or gluing.

    I

    should add here that

    w e v e

    followed

    this approach ith all of the projects

    shown in Wood mith and haven t had any

    problems.)

    Laying out th~ boards

    so

    they

    ca n

    be

    planed easily is a step that s rarely men-

    tioned (and often forgotten). But if the

    hoards are not going in the right direc

    tion rplaning, you ll be faced with a lot of

    tear-out problems.

    There s also a m is co nc ep tio n ab out how

    to determine the proper

    grain

    direction for

    1.laning. When looking a t the face side of a

    board, the grain usually fonns a series of

    Y patterns that point in one direction.

    There s a natural tendency to want to

    move the plane in that direction

    with

    the grain.

    However, the only way to tell if the

    grain

    is

    going in the right direction on the

    f e of the board is to look al the grain on

    the edge of lhe board.

    F lA T T E N IN G A P L A N E

    \Vbe you buy a new plane, it s reasonable

    to expect that the sole of the plane is per

    fectly flat. Unfortunately, that s not

    always the case. ln fact. most new

    planes

    have a little problem area right around the

    throat (mouth).

    This area is critical because that s where

    allthe action is. lithe sole is warped (form

    ing 8 high spot or low spot at the throat). it

    will affect the

    cuulng

    action of the 1)lane

    iron (usually causing excessive chatter ).

    lII(lH SPOT. If the plane has a high spot

    around the throat, it s usually not toomuch

    of

    a

    problem because all you have to do is

    flatten the high spot flush with the rest of

    the sole. This is relatively easy to do by

    sanding the bottom of the plane on some

    silicon carbide paper.

    T81>ea sheet of 22O-grit silicon carbide

    paper

    to

    the table of the table

    sa w

    and take

    a few careful strokes. The high spots

    should become quite visible as shiny areas,

    Keep working the

    plane

    over the paper

    until these areas arc flush with the rest of

    the sole. Then switch to 320 and finally

    400-grlt

    paper

    to smooth out the sanding

    marks.

    L O W S PO T. If the sole has a low spot at

    the throat. it s more of a challenge.

    Y ou

    have to flatten the entire sole of th. plane

    to get this area flush. This is too much

    work for sandpaper. but it call b e . done

    with silicon carbide slurry.

    This slurry is made with powdered slli

    eon carbide powder mixed with enough

    water to fonn a thin paste. I start with 8 0

    grit silicon carbide powder.

    and

    work to

    finer grits

    as

    the sole is

    flattened.

    (Note:

    Silicon carbide powder is available at lapi

    dary supply stores. Look in the Yellow

    Pages under Lapidary.)

    The only mail order source we

    know

    of for

    the aluminum oxide grinding wheels re

    commended in our

    article

    is Woodcraft

    Suppl l

    (Tbese grinding wheels are made

    by

    Bay Stal.

    Ab''(lllj''e8, but they're very

    similar to the

    Nortoll wheels.)

    The 6 diameter aluminum oxide wheels

    offcl'ed by

    Woodcroj

    all have ', arbor

    holes. If your grinder has a v arbor. you'll

    h ve to use bushing to reduce the ~~

    diameter to

    V .

    Doth the bushings and the wheels can be

    ordered from IVood~rnft Supply. Their

    new address is;41 Atlantic Ave .. Woburn,

    M A 01888 . Catalog: 2.00 .

    Could you possibly give me a source for

    the grinding wheel you recommended that

    has

    a

    This bench isa nice companion piece for the

    Trostle Table in this issue; and it's also a

    good

    warmup project.

    Things

    always

    seem to

    go

    easier the second time

    around.)

    The same method of construction is used

    on this bench

    as

    on the table, with only

    minor differences.

    TH t: S EAT .The assembly of the top (seat)

    is the

    same.

    Glue up of enough boards

    to

    get rough dimensions of 14 wide by 48

    long. Then trim the ends square to 8 final

    length of 47~ and cut the tongues v .

    long this t ime) on each end.

    Next, the side thieknesser strips are

    glued to the edges. and the end thicknesser

    strips

    ar e

    mounted with the slotted

    screw

    method.

    To

    complete the top, the

    en d

    caps

    are

    cut and mounted.

    Tllf; TRESTLES. However, the trestle

    assemblies On this bench are slightly di

    ferent than the table. First the notches

    (mortises) in the three-board assemblies

    for the arms and bases are cut to allow for

    only

    a

    Single-thickness

    rail ( Y O W ) .

    Second. the arms on the bench trestles

    are long enough to

    be

    mounted directly to

    the side thicknesser strips, which means

    their overall

    length

    i~

    2 - only 2

    less

    than the width ofthe seat.

    Also ,

    inorder to

    provide a

    little more leverage for the

    bases, W e made them the full width of the

    lop

    N

    long).

    A nd

    third, all four

    of

    these

    p ie ce s a re

    tapered, but this time the taper starts t

    down from the tOPedge, and ends Y from

    the mortise. For the a rm s th is means a

    13

    taper, and for the bases it's a 10 taper.

    Ti lt: L EG S- The legs (uprights) are made

    exactly the

    same way as on

    the table -

    glue up three boards, trim the faee sides to

    allow for a chamfer on the edges of'the

    base

    and arm, and finally, counterbore the holes

    for the carriage to

    hold

    the rails in place.

    TIlE lUlL. The rail has to be cut to Iinal

    length so

    when

    it's

    mounted,

    the trestles

    o f

    the bench fit comfortably between the

    trestles on the table. Then to mount the

    5 ,3t,

    drill holes in the side thicknessers (of

    the seat) for rosan

    inserts

    and counter

    bore

    holes

    in lhe

    tresue arm s for

    hex

    head bolts.

    Iound it much easier to finishsand all of

    these

    pieces

    (the

    arms,

    bases, legs. and the

    rail

    before

    the trestles

    ar e

    glued

    up.

    And

    then before final assembly of rail and seal.

    Iinished

    a ll

    the pieces with Minwax poly

    urethane. I also mounted adjustable level

    ing

    pads

    to

    the bottoms of the trestle bases

    to allow for variatiens in the Ooor. 1

    figured it had to be the floor that caused
