HOW TO USE A CIRCULAR SAW FOR BEGINNERS - PART 2
HOW TO USE A CIRCULAR SAW FOR BEGINNERS - PART 2
In part one of this video series we reviewed circular saw parts and uses. Part two of this series covers the two most basics types of circular saw cuts (cross cuts and rip cuts) so that you can be comfortable using this saw today. In addition to learning about the two types of circular saw cuts, we will also discuss blade selection, safety, and other tips and tricks.

0.03 -> if you've missed part 1 of this video series
then take the time click the link and go watch
4.14 -> that video in that video or talk about the various
parts of the circular saw and its basic uses but
9.99 -> now in this video we're cutting stuff thanks for
joining me alright first things first which type
15.66 -> of saw blade to use I have two different types
in front of you the first one right here is is
20.97 -> the normal blade that comes with a saw this is
a 24 tooth 7 and quarter-inch saw blade now this
28.14 -> is good for for one thing and it's eating wood
it's super fast it cuts very very fast the only
34.8 -> downside to this blade is it's cut quality now
when the blade is is is new it cuts pretty clean
41.34 -> even on plywood but as it gets older man you
got to look out the next on the list is a 60
48.24 -> tooth saw blade this blade is what I use to cut
finished plywood amazing enough it produces a
55.26 -> very clean cut with little to no tear out so
I don't want you to think that these are the
59.67 -> only two saw blades out there because there's
not these are the the ends of the spectrum if
64.95 -> you will there's there's blades in between there
but what I want you to learn from this is I want
69.24 -> you to learn to ask yourself two questions before
you even plug this all in the first question is
74.07 -> what am i cutting and second how do I want that
cut to turn out so putting those questions to
79.53 -> use I'm gonna go ahead and go with the 60 tooth
blade here because I'm really more interested
85.08 -> for this demonstration for a clean cut they aim
for a faster one so while I attach this blade I
90.99 -> want to talk just for a few seconds about safety
now of course when you're working with these saws
96.66 -> changing out the blades or doing anything
like that please remember to unplug them or
100.89 -> disconnect the battery and of course lastly I
would wear some safety glasses at least to the
106.53 -> minimum while you're using these saws because
they love to throw sawdust and I love to throw
111.36 -> bits of chunks of plywood around in the air all
right they have it let's do some cutting all
118.77 -> right so we're all set up ready to go the first
thing that we're gonna do is make a crosscut on
124.74 -> this dimensional or 2x4 right here one of the
most invaluable tools that you'll have that goes
129.93 -> along with this circular saw is a speed square
I'm to make another video on this specifically
135.78 -> about the details of this but it's just a square
and it's a great way to take a pencil and make
141.96 -> a square line on a piece of board or anything
else before we make a cut what we need to do
147.81 -> is set the blade depth so if I put the saw down
on the piece of material the blade needs to be
157.35 -> set lower than the material itself by about 1/8
to 1/4 of an inch so just about like that and
165.63 -> we lock it down with the lever so let me toss on
pair of glasses here if you look also now at the
173.4 -> front of the saw blade you can see that there is
a zero line and this zero line represents where
180.93 -> the blade is cutting exactly so we are going to
line up the zero line with our pencil line for
188.28 -> our cross cutter and you're gonna squeeze the
trigger to get the blade going first and then
193.17 -> slowly push the saw into the material making sure
that your cutting on the side of the pencil line
198.33 -> that is the piece you don't want and as you can
see the material falls right to the floor it's
207.12 -> unsupported so that the material won't get bound
up what you don't want to do is ever cut in such a
213.33 -> fashion like this whether you're trying to cut
the center and is supported on on either end
219.63 -> if you try to do this the board is going to bend
in the middle and bind up on the saw let me show
227.04 -> you then a cross cut with the speed square we're
going to put the speed square down on the board
234.39 -> and we're going to hold it and we're gonna allow
the the shoe of the saw to ride against the nice
241.56 -> straight edge squeeze the trigger to get the blade
fully up to speed before you go into the material
251.26 -> and push the sauce slowly through the material
trying to keep the shoe tied up against the speed
258.67 -> square and there you have it alright so now that
you got the cross cut down let's shift our gears
268.6 -> and talk about plywood and ripping plywood to
length and width so there's a few ways that you
274.15 -> can actually do this with this circular saw the
first way would be in no particular order would
281.71 -> be taking a straight edge like a level drawing
a line with a pencil and then you can freehand
288.82 -> that just like we were doing cut in the cross cut
in the two by fours another option is to use the
295.9 -> straight edge and a clamp and one on the other
side and you clamp these down to your specific
305.26 -> distance and you take the edge of the shoe
and you ride the saw against the edge of the
311.47 -> straight line or the level in this case that's
an option another option would be to use they
317.83 -> sell these tools right here it's a guide and
it's got clamps on either side and it's same
324.7 -> principle but these can go on here and then you
clamp down and you use a circular saw again same
333.94 -> thing right in the shoe against the straight
edge and yet there's one more option that you
338.8 -> can do and that option is to use this I don't
know jig that comes with the saw it slides into
344.98 -> the front of the saw like this and you can
adjust it accordingly and then this piece of
351.4 -> metal rides on the edge of the plywood and helps
you to rip it all the way down works pretty good
357.55 -> I can't say I ever really used it much but so
those are some of the options I wanted to make
362.62 -> you aware of those first but we're gonna
snap some lines here or do some free cuts
367.15 -> and let's get right at it let's go alright so
we're going to put down the line on this side
374.33 -> let's just call it an inch-and-a-half so
I'm making a mark just and a half on the
379.4 -> other side and what I'll do is I'll actually
use a straight edge to draw the line for me
387.77 -> you could use a chalk line as well this okay
and so first things first take that out we'll
401.63 -> set our blade depth now my eyes going to
stay in this case on that zero line so as
412.82 -> I'm pushing I'm following the pencil line
and the zero line with my eye here we go
432.24 -> all right salt comes to a stop and you take
a look and it's pretty wavy but that's it if
441.06 -> you're making some rough cuts this is perfectly
acceptable through sheathing a house or doing
445.08 -> anything like that that things don't have to
be perfect that's kind of the fast way to do
448.92 -> it and of course if you're looking for more of
something perfect then I would use one of the
454.71 -> methods that I mentioned before something like
this or a straightedge or even a track saw which
460.98 -> I didn't mention before and companies like Festool
and I think Craig make these systems where it's
467.07 -> a track that you just set down on the plywood
and the saw has grooves in the bottom and the
472.74 -> track has grooves and it just slides in it's very
fast and and super nice but also very expensive
478.68 -> so that might be an option but if you're first
getting started out it might be too much money
483.42 -> for you some of these systems again may be a
little bit slower but they work just as well
487.71 -> all right so the last thing I'm gonna show you
I drew another straight line on our plywood is
493.56 -> more of a technique as I said before I was using
my eye to view the pencil line and to line up
501.39 -> the zero mark sometimes that doesn't work out
well and your eye can get off and you can get
508.83 -> off your line especially when the material
is very short because when the saws overtop
512.94 -> you lose your line it goes away and so what
I normally do is as I'm cutting I'm actually
521.61 -> not looking at the zero line but I'm looking at
the blade as it's cutting through and I'm using
528.6 -> the blade as the guide to guide me through that
pencil line and it looks something like this so
537.12 -> as I'm pushing the saw through I am watching
the blade away at the pencil line well there
547.64 -> you have it that's the basics of this circular
saw I hope this video has been helpful for you
552.68 -> guys just getting started and just getting to
know the circular saw I will be of course making
557.15 -> more advanced one where we're talking more about
plunge cuts and bevels and all the other things
562.34 -> that this saw can do so look for that coming
out here soon on my website thank you guys so
568.4 -> much for hanging out with me today in the shop
and I look forward to seeing you guys again soon
