    I did a lot of sanding in the 15 years between my first run-in

    a dull, rusty handplane and my eye-opening test drive with a

    sharp one. Unfortunately, thats not an uncommon experienc

    sharp handplane can work wonders, going from machine ma

    to a glass-smooth surface in minutes. A dull plane can do a l

    damage, both to your lumber and your psyche.

    The good news is that its easier than ever to start worki

    with your first handplane. Years ago, your choices were to b

    inferior new plane that needed a lot of tune-up work or an ol

    quality plane that also needed a lot of tune-up work. Today t

    market offers many excellent new planes that require little m

    than a five-minute sharpening before the shavings start to flI still keep a scraper and fine sandpaper on hand to fix th

    occasional tearout, but my smoothing plane has eliminated

    dusty hours of sanding that used to accompany every projec

    addition to saving time and leaving a smooth surface, the ha

    plane excels at creating dead-flat surfaces and crisp chamfe

    hallmarks of fine woodworking that are impossible to achiev

    sandpaper alone.

    B Y A S A C H R I S T I A N A

    When I started out as a woodworker, I didnt know much abo

    sharpening and therefore couldnt get my hand tools to work

    So I used sandpaper to prepare surfaces for finishing. Sandphas a short learning curve, and I picked up most of the tips

    ed from a great Taunton Press video on finishing by Frank Kl

    Truth be told, Ive since switched to handplanes for a lot o

    surface prep. A few passes with my sharp No. 4, and I usuall

    a dead-flat surface ready for finish. But the handplane doesn

    work with every type of wood and figure, so I still break out

    random-orbit sander and trusty sanding blocks quite often.

    I dont mean to say that sandpaper works better than ha

    planes and scrapers. But sandpaper is a great equalizer: It w

    on every wood and in nearly every situation, while handplane

    must be perfectly tuned and razor sharp to work at all. With

    paper and a few tips, anyone can create flawless surfaces.

    My sense is that sanding is slower than planing and scra

    even when you factor in sharpening time for the hand tools.

    shootout will test that assumption. Maybe sanding is easier

    and faster.

    Get sharp first. Using waterstones and a hon-

    ing guide, Pekovich polishes a narrow band at

    Easier than benchdogs. A simple planing stop

    clamped across the benchtop is all you need to

    secure the work, and it lets you quickly flip the

    piece or change to another.

    Dont bother with hidden surfaces. To

    time and wear on the blade, plane only th

    outside face and bottom edge of each ap

    Afterward, chamfer the bottom edges wit

    block plane.

    Better than a dust mask. Connect a shop

    vacuum to the sanders dust port to keep dust

    out of the air and avoid clogged sanding pads.

    Better vacuums switch on with the sander when

    the tool is plugged into an onboard power outlet.

    Gang up parts. Start with a coarse grit, P80

    or P100, to remove burns and mill marks. Avoid

    rounded edges on narrow stock by ganging two

    narrow pieces together. Note, this only works if

    the surfaces are level.

    Change disks frequently. Dont be shy

    using more than one disk of the same gr

    before moving to a finer abrasive. A worn

    clogged disk will slow down the work.

    power sanding: deal with dust and dont skip a grit

    handplaning: start sharp and use simple stops

    Holding narrow work. A simple L-shaped jig

    Sand evenly. It is critical to work the surface

    evenly and systematically to guarantee it will

    end up flat. Its easy to linger in one area and

    create a hollow, which you may not notice until

    Plane in two stages. First, level any high

    spots until the top is flat on both sides. After

    resharpening the iron, set the plane for a light

    cut and take a series of smoothing passes over

    the entire surface of the show side only.

    Finish by hand. Begin hand-sanding with the

    last grit you used on the random-orbit sander,

    usually P220. Work the sanding block in the

    direction of the grain to remove the last swirl

    marks from the sander.

    Dead flat and smooth. Careful surface prep-

    aration pays off, especially on your projects

    broadest, most visible surfaces.

    How to tackle end

    grain. Start by lightlylubricating the planes

    sole with paste wax.

    To avoid chipout at the

    far edge, take a few

    short passes from that

    end first. Then rotate

    the piece and work

    normally, stopping short

    of the far edge.

    Sanding block breaks edges, too. Easing the

    sharp edges makes them friendlier to fingers

    and more resistant to damage. Turn the block

    45 for a few passes with P150-grit paper to

    create a light bevel.

    MIKE: YES, PLANES ARE FASTER

    BUT DONT RUSH

    Ive always contended that handpla

    was faster than sanding, so its nice

    know that I havent been laboring u

    false assumption. That said, I plann

    half an hour to prepare these parts

    took twice as long. As always, the

    was in the details. With perfectly st

    grained lumber, planing is a breeze,

    in the real world, thats rarely the c

    The quartersawn grain on the legs w

    especially tricky and prone to tearo

    spent extra time scraping those pa

    and would have done even more if I

    been keeping an eye on the game c

    During the contest, I used just o

    bench plane and a block plane to sh

    that you dont need to buy a lot of hplanes to get started. But I wound

    doing a lot of adjusting for heavy an

    cuts. Normally, Id have set up a No

    plane for flattening parts quickly an

    No. 4 for final smoothing. That wou

    saved some time and effort.

    ASA: SANDING IS STILL

    A SAFE FALLBACK

    Mike beat me comfortably, but not

    much as I expected. He ran into so

    tearout, and that took some fussing

    overcome. I had no such problem. S

    paper handles the toughest grain w

    a hitch. But now Im sure that it tak

    longer. A few online comments sug

    using a belt sander for speed, but t

    random-orbit sander is easier to con

    Under a coat of oil, my tabletop h

    a tiny bit more blotching, but that m

    be due to the different boards we st

    with. And Id say my legs and apron

    better, as his still had some tearout

    On future projects, Ill stick to m

    approach: When the wood allows, I

    use handplanes. But trusty sandpap

    always my backup plan. Also, I thin

    ing is easier for beginners. Just wor

    surface evenly, move patiently throu

    grits, and use a block for hand-sand

    What they learn

    When to stop. The final grit depends on the

    type of finish: P220 for shellac or polyure-

    thane, or as high as P600 for an oil finish,

    especially on blotch-prone woods like cherry.
