All language subtitles for 5 Expert Table Saw Tips

[Music]

hi I'm Nicki angler author of

woodworking wisdom and a few other

woodworking books and I'm going to show

you a few professional secrets tips and

techniques that will improve the ease

and accuracy of your table sawing

operations got a crosscut aboard to a

specific length so first of all you

measure that length in this case I'm

just gonna measure 12 inches make a mark

at 12 and then I always like to take a

square and extend that mark at least a

inch or two so I can make sure that the

cut is following the line now how do you

line up your mark with the saw blade

well you can eyeball it and hope you're

on right on the money and you almost

never are some people like to to move

the wood a little past the cut and then

creep up on it making successive cuts

until they finally get weather where

they're going but there's a much simpler

way you can simply take your square put

it right on your mark and then move the

wood until it just touches the tooth of

the blade there we go

we're lined up to make the cut

like I said right on the money okay how

do you know that the cuts you make are

perfectly square and that your miter

gauge is set to a perfect 90 degrees

well you can use a square of course and

a fence as long as the fence is parallel

to the blade you can use a square to

check that your miter gauge is square to

your fence so that's pretty close but

it's not precision to absolutely be sure

take a scrap of wood we're going to make

an X somewhere in the middle of that

scrap and we're going to cut through the

X

okay now we're going to take this scrap

and we're gonna put it against the fence

which we know is perfectly straight okay

now that goes together pretty darn good

but if I flip it it should also go

together

up there's a gap there's a small gap

right there against the edge that's

against the fence at the face okay

if that happens I've got to move my

miter gauge counterclockwise just a hair

now that should be square

if the gap had been on the other side

away from the fence I would have had to

move the miter gauge clockwise let's try

this once more and more time and see if

I've corrected the problem

there you go perfect

[Music]

when you're ripping a piece of wood and

the wood has been properly dried or

sometimes it's just the wood itself the

kerf the cut left by the blade will

begin to close behind the blade and

pinch the blade this is due to what is

called reaction wood there are tensions

in the wood that cause the wood to

distort as you relieve it by cutting it

now if you don't have a splitter and

this is a problem for you you can keep a

few wedges handy and put those in the

cut behind the blade show you

just start the cut let the blade come to

a full stop put the wedge in there we go

[Music]

[Applause]

that's it

[Music]

every now and then you may have to cut a

piece of plastic on your table saw and

it's very unlikely that you'll be

keeping a plastic blade around because

it's so infrequent but don't worry you

can make a good cut in plastic with a

plywood blade or something with a lot of

teeth just turn the blade around so the

teeth are facing backwards this helps

clear the guts so you don't they don't

get filled up with plastic shavings and

begin to melt making a burned crispy cut

here I'll show you I've got a plywood

blade on here and as you can see the

teeth are facing away from the direction

of the cut

[Music]

[Laughter]

now we had a little melting going one

you can see that these pieces have have

fused but the cut itself is real clean

[Music]

you want to make a bevel rip and it's

got to be precise very accurate that

means you have to tilt the saw blade to

a precise angle now the old way to do

this what's to use a sliding T bevel and

a projector now let's say that we want

to tilt this to tilt at 22 and 1/2

degrees the blade is actually set at 90

degrees so 22 and 1/2 from 90 is 67 and

1/2 so we set the protractor to 67 and

1/2 degrees and we take the sliding T

bevel and we set that to the same angle

now we're going to tilt the saw blade

until the edge of the sliding T bevel

touches the blade all along the face and

right there is pretty good ok that's not

a bad way to do it but you can get a lot

more accurate if you have an inkling

ok these measure these measure the angle

digitally and the measure to a tenth of

a degree now we're going to take this

got it turned on here

and we're going to zero this out first

of all now I've got it turned away from

me so I'm gonna have to ask my buddy

Travis to see if that is on 0.0 ok all

right

he says I got it now I'm gonna put this

on the blade and what am i reading right

now sixty seven point six so I'm a tenth

of a degree off ok that may not seem

like a like a lot but if we were making

an octagon which which has mitered

angles of 22 and 1/2 degrees all the way

around that's 8 angles and by the time

we get to the last angle

we'd be almost 1/8 of a where we would

be point 8 degrees off almost an entire

degree off enough to show a gap so we're

going to let's see I'm going to turn

this just a little bit and try to get to

67 and a half

tell me if I'm good I'm going in the

right direction is that the right

direction or the wrong direction

wrong direction okay let's go back tell

me who right there

okay 67 and a half degrees precisely

[Music]

you can also use this in kilometer to

set the miter gauge precisely if you

want to just take the miter gauge itself

and you'll notice I have an extension on

it clamp the extension to the saw table

there we go now we'll take the inclined

honor we'll zero this out yeah it's

already at zero and then we stick it to

the miter gauge and it should read

ninety and it comes awfully close now

we're going to angle the miter gauge and

let's do sixty seven and a half degrees

like we did with the blade angle we're

okay that's what sixty six point four

come back a little bit sixty seven point

three point four because it when I turn

type it down sixty seven point four oh

there we go sixty seven point five so

now when I cut with this I'll be making

a twenty-two and a half degree angle

[Music]
