Before sliding miter saws existed, I cut stair treads with my
sweet little 12-point handsaw and a marking knife. After that I
used the Delta Sawbuck for a while, a truly awful tool that was
like a Skilsaw riding on two rails.
In the years since then I've been through a number of miter
saws; for the last five, I've been doing my stair-building work
with a 12-inch Hitachi C12FSA sliding compound miter saw. From
the beginning, I liked this tool; I figured, hey, what else
could you want from a saw?
Well, I found out the answer to that question last summer and
fall, when JLC loaned me a Hitachi C12LSH dual-compound sliding
miter saw.
Like many large sliding miter saws, this tool has excellent
cutting capacity and comes with a laser marker. But it also has
two features not found on other saws: a digital display that
shows miter and bevel angles, and a slide system that allows
you to position the tool close to a wall.
Unusual Slide System
One of the qualities I'd appreciated in my previous saw was how
light and easy the slide and chopping action felt. The C12LSH
retains that excellent action — even though the slide
system is completely different.
The new system allows you to lock the rails so that they don't
slide out the back. In this way the tool is similar to a
radial-arm saw; the motor and blade move but the rails are
fixed, so you can sit the tool against the wall. My older saw
— which doesn't have this feature — takes up twice
the room and never seems to fit anywhere.
Its slide system makes the C12LSH ideal for shop use because it
can be assigned to a fixed station in line with other machines.
The feature would also be great on job sites where space is at
a premium.
LCD Display
Another unique aspect of the C12LSH is its LCD display, a
digital readout attached to the top of the tool with a flexible
fitting. At first, I considered this feature a gimmick —
but I changed my mind the first time I had to cut a whole bunch
of stair balusters at 33.5 degrees.
In addition to the usual scales, this saw has a digital
display that indicates miter and bevel settings down to the
nearest .5 degree.
Early in my career as a stair builder I used a bevel gauge to
measure the angle on the tops of balusters and to transfer that
bevel to the saw. But several years back, I learned an
incredibly useful piece of geometry: The inverse tangent of
rise/run is the slope of the stairs (or any right triangle) in
exact degrees. Knowing this, I can go straight from the
calculator to setting the angle on the saw for baluster and
skirt cuts.
I could also use the miter gauge, but viewing the numbers on
the display is faster and easier; there's no need to count off
graduations or to eyeball the halfway point between them. Using
the display is simply a matter of flipping a switch to turn it
on, swinging the table left or right, and reading off the miter
cut.
The digital readout makes it possible to cut multiples of the
same thing, stop to cut something else, and then quickly go
back to the original angle setting.
The left side of the display is for miter settings, and the
right side is for bevels. The readout is especially handy for
setting bevels because the bevel scale is small and hard to
read when you're balancing a heavy part of the machine. The
display is at eye level and shows an absolute number. Its only
shortcoming — a minor one — is that the smallest
increment it will do is .5 degree.
Of course, there's no need to use the display for every cut; if
you want, you can turn it off and use the regular scales and
detents.
Laser Marker
One of the hottest new features on miter saws these days is the
laser marker. When the laser is on, it projects a visible red
beam across the stock in line with the blade.
When activated, a built-in laser projects a visible beam in
line with the blade.
Initially, I found the glow a distraction, and I'd often turn
the laser marker off. But the more I used it, the more useful I
found it to be. I now rely on it regularly for certain
tasks.
For example, sometimes I need to trim an uneven strip off the
end of a piece to make something fit. The particular angle
doesn't matter — I just want to make the blade hit the
line I drew on the material, or clip one edge and miss the
other. The laser makes it much easier to do this, because the
beam shows in advance exactly where the blade will go.
Micro-Adjustments
For years, when I needed that one-degree change in miter angle,
I would tap the saw over by banging on the handle. The saw
never stopped quite where I wanted it to.
Now, with the C12LSH, I can calmly watch the miter display and
make slight adjustments by turning the micro-adjustment knob on
the front of the saw. The knob — which is connected to a
rack-and-pinion mechanism — allows you to make fine
adjustments easily and accurately.
There is a similar mechanism on the back of the saw for setting
bevels. In some ways it's even more useful than the one for
setting miters; normally when making fine adjustments to the
bevel angle, you have to fight gravity, but with the C12LSH's
micro-adjustment knob, you can simply dial in the exact setting
you want.
Both knobs work well with the digital display: To make fine
adjustments, you turn the knob and watch the display. I do have
one gripe, however, which is that the knob for adjusting the
miter would be easier to use if it were larger.
A knob connected to a rack-and-pinion mechanism makes it easier
to make fine adjustments to bevel settings. A similar
micro-adjustment mechanism on the front of the saw controls
miter settings.
Final Judgement
In terms of power and cutting capacity, the C12LSH is on par
with competing models. What really stands out about the saw,
though, are its features and how well they work together
— particularly the micro-adjusting knobs.
In fact, I found it hard to let go of the C12LSH at the end of
the testing period. It's a fantastic saw for use in the shop
and an equally good saw for use on site — the only
problem being that at 66 pounds it's one of the heavier models
around. (Bosch's top-of-the-line model weighs 59 pounds and
DeWalt's and Makita's weigh 53 pounds apiece.)
The weight is not a problem for me because I do most of my
cutting in the shop, and when I go on site there are usually
people around to help me load and unload. But for someone who
works alone and has to haul his tools in and out of the truck
every day, this otherwise excellent saw may not be as
suitable.

Circular
Saws
by Patrick
McCombeHigh-Power Cordless.
Way back
when, my first cordless circular saw was capable of little more
than cutting pine shelving. Fortunately, times have changed:
DeWalt's newest cordless model has the muscle and runtime to
serve as a real alternative to your corded saw. Powered by a
36-volt lithium-ion battery pack, the 7 1/4-inch DC300K makes
up to 116 cuts in a 2x10 and can easily slice through tough
materials like LVL and treated lumber, says the maker.
Additional features include a toolless blade clamp and a
lightweight magnesium shoe. With a plastic case, charger, and
one battery, the saw sells for $380. DeWalt, 800/433-9258,

Short Cut.
Since you probably
hardly ever use your 7 1/4-inch circ saw's full depth-of-cut
capacity anyway, why not save your arm and downsize? At 8
pounds, Ridgid's new Fuego 6 1/2-inch Framing Saw (model R3203)
is the lightest corded framing saw available, says the maker. A
smaller-than-average blade, a magnesium blade guard, and a
composite shoe help keep the weight down. The saw cuts up to 2
1/8 inches at 90 degrees and up to 1 5/8 inches at 45 degrees.
It costs $140. Ridgid, 800/474-3443,

Square Deal.
When it comes to
getting more bang for the buck, Hitachi's C7SB2 — which
commonly sells for less than $90 — is hard to beat. Even
putting price aside, I consider this pro-duty sidewinder a
stellar performer. It's well-balanced and powerful, and it
bevels to 55 degrees. The price includes a case. Hitachi,

Crank it Up!
When it comes to
lifting a steel beam or other heavy building component, your
first inclination may be to bring in some additional help
— but even with extra hands, lifting weighty objects 8 or
10 feet is extremely risky. Instead, be smart and use a
material lift like Genie's Superlift Contractor. With its
650-pound capacity, the mechanical lift can reach up to 24 feet
(depending on the model). The manufacturer says it fits through
a 3-foot door and can be hauled in the back of a pickup. Prices
start at $1,435 for the 12-foot model and $2,255 for the
24-footer (based on 2006 pricing). You also might be able to
lease the product from your local rental yard. Genie,

Reach Higher.
No tool spares your
back like an all-terrain forklift. Bobcat's newest machine, the
V638 VersaHandler, boasts a maximum reach just shy of 39 feet
and a 6,700-pound capacity (850 pounds at maximum reach).
Hydrostatic transmission allows the operator to shift on the
fly, and an optional heated and air-conditioned cab maximizes
comfort. Prices start at about $80,000. Bobcat, 800/743-4340,

Cart Blanche.
Perhaps back in your youth you could
muscle around solid-core doors and sheets of 12-foot drywall,
but today it might make more sense to use a Troll Panel Handler
112. The cart has a 250-pound capacity and holds up to four
1/2-inch-thick panels. An adjustable clamp on the handle keeps
the load secure; two casters — one straight and one
swiveling — make the cart to easy to maneuver in tight
spaces and long hallways. It costs $150. Telpro, 800/448-0822,
