here we go hey you guys what's going on
my name is Mark from woodworker source
and this is a big ol chunk of twelve
quarter cherry what is twelve quarter
mean it's just the fraction that denotes
the thickness of this lumber you've
never heard that term before that just
means it's about three inches thick 12
quarters twelve quarters of an inch
twelve divided by four equals three you
are correct
good job wood like this is big it's
heavy it's a little harder to cut and
sawed and work with because of that so
let's get to some tips so it's really
common to get burns and
less-than-stellar cuts unless you're
using the right blade let me show you
what I mean by demonstrating by making a
couple of rip cuts using a 52 card is
baby right here so this type of blade is
usually just fine if you're cutting half
a inch for cord or even anything up to
like two inches thick it's just fine for
general purpose cutting ripping cross
cutting all that but this type of blade
really reaches its limits when you
introduce twelve quarter lumber
three-inch thick lumber SM is just so
thick dense that kind of blade just has
met its match so let me show you what I
mean

okay guys that was that that first cut
really hard to do it give me a lot of
resistance obviously gave me a bunch of
burn marks too that's just kind of the
way it goes when you use a blade with
that many teeth on a rep cut through
that thick of wood now let's swap in
that ripping blade you'll see a huge
difference so a dedicated ripping blade
has an aggressive for Drake it's got
deep cuts between the teeth plus it has
fewer teeth than you might be thinking
and this one that I'm using only has 24
for example and seriously this is the
type of blade you want to use if you're
gonna be ripping hardwoods and you want
to get nice crisp clean cuts
okay guys did you notice that the cut
one really fluid it was really nice plus
there's no burn marks in this piece and
the blade was at full height so that's
just really a testament to the reason to
use dedicate ripping blade especially
and thick hardwoods like this okay so
one trick you might be thinking of doing
is maybe taking that cut in a couple of
passes and what I mean by that is you
start with the blade just an inch or so
above the table you make the cut you
raise the blade a little bit more you
make the cut again and then you raise
the blade the final amount and make that
final cut what that does is it puts a
lot less stress on your tools on that
blade and as you push you just you don't
feel like you're fighting that board
nearly as much you might reduce the
amount of burns and stuff you're gonna
get and pretty that's what I thought too
I gave it a shot I didn't have any
better result it's still burned just as
much the cut went a lot easier that's
for sure but I did have to make three
passes so I didn't save any time and
only saved a little bit of pressure I
had to put on the board didn't get any
better cuts so I think the better way to
go about this is just use a ripping
blade okay guys thanks for watching we
really appreciate it I hope you learned
something if you did get that little
thumbs up a little tap and spread the
word thanks spike
