this is the make even badging video for the metal
chop saw so we're going to cover its purpose safety and then how to use it
so this can be used for making either straight or angled cuts in metal that's mild steel or softer
so that can be aluminum bronze steel galvanized steel but you don't want to cut hardened steel
titanium stainless things like that that's just going to destroy the teeth the teeth on this blade
are carbide so it's a steel blade that has carbide which is a harder form of steel welded onto each
tooth and as opposed to a wood like that blade in a similar chops on the wood shop these are just
have a lot more steel behind them so they're a lot stronger it also spins much more slowly so
that's that's what this is for um in this case it's the back rest that is changing the angle
versus in the wood shop it's the whole head of the saw that's changing so that means if you have
a long piece of metal it might be hitting the door or any other tool so that's just something to take
into consideration we'll get that later so that's the purpose in terms of the safety for this tool
it's it's actually another name for this is a cold cut saw because the alternative to it is
an abrasive wheel so it's like an angle grinder abrasive wheel that's used to cut that some of you
might be familiar with but those are really dirty they just produce a lot of dust they're very loud
and they wear out quickly and you can't use them on softer metals because it just gums them up
and they get very very hot so this is called a cold cut saw because it takes the heat of
the cut and puts it right into the chip so after you're done cutting most of the time the piece is
actually pretty cool versus cut on an abrasive saw be very very hot so that's pretty nice
which means that heat isn't a super big safety risk here it also
in terms of safety you just really want to be sure that no body parts are near the blade so make sure
to have your hair tied back have um any necklaces or ear buds or anything tucked away so it won't
get caught in the blade it spins more slowly than a wood shop one but it's still super powerful
so you really don't want anything hot in there there's no holding the work piece by hand here
unlike the woodchuck it has to be clamped uh and then you're just using your hand to
to pull down you're not you're not holding anything with your hands because it'll just
it has the risk of pulling it right out of your hands now being really bad especially with metal
it's really loud so you're going to want to wear ear protection
when you're using it and be mindful of the chips obviously in the metal shop you're going to wear
eye protection but in this case just be mindful that chips might end up in your shoes or just
need to be careful especially steel it's like little razor blades they're very sharp
and you want to in general stay out of the way of the blade so you're gonna cut without you
know with your body outside the line of fire blade but in terms of safety if your workpiece is really
well clamped and it isn't going anywhere then you should be in pretty good shape
so before we start the machine is off and we're just going to look quickly at the teeth
to make sure they're all there and this blade looks pretty new
one nice thing about these carbide blades is that they should last a pretty long time
this blade looks pretty great and then there's actually a replacement right on the wall
if we need it and this is a 16 or 14 inch blade so it's a pretty darn big big blade
and that's the deal so we're just going to show you how to use it now so on the clamp this
this is like a half nut that engages on this thread so if you want to slide it you can just
lift that up and pull it out we're going to cut this thing which is kind of a weird shape so we
just need to make sure that we clamp it so that it can't move so if we were to clamp it say like this
it could slip and pop up and we wouldn't want that so we're going to clamp it like that so
it has nowhere to go I'm just going to slide this forwards that this half nut and it's called that
because it's like half of a full nut is that was stopping it from going forwards right there so
you just have to lift that up now it can slide all the way forwards drop that down into the threads
and clamp it and now our material is secure I want to make sure that this is clamped so that's
not going anywhere and this is another clamp that can be used so it could be placed here
and you use it to clamp down on your material I think in this case
this clamp is probably sufficient so we'll do this cut first and then we can look at changing
the angle it doesn't look super square right now if you want the piece to be super square
then you can take a square off the wall and put it against the fence against the
blade and adjust the angle with this guy to make sure that it's it's really square
right now we just need to be tight so we're gonna turn the tool on and put on hearing protection
and standing out of the way of the blade
uh we're gonna bring the head down really slowly so it takes just little bites at a time
so also compared to an abrasive saw there shouldn't be many sparks this piece is totally
cool to the touch it should mostly just be chips of metal coming off which is nice you're not gonna
light anything on fire by accident so now we'll look at changing the angles so I'm just gonna
take this out and so there's a pin here and this is not a super highly calibrated fence so
there we go so it says 45 there are little angle indicators right on here
but and I'm just going to turn this off because my hand is underneath but you should if you really
want it to be precise I would get a get a tool to check it and then you just tighten it down
and there you go um let's say you had something small obviously at some point it's just going
to be too small to cut especially in this orientation but if we put it back
to 90 degrees like that and we wanted to do something shorter I mean this might just be too
short but as an example you can put something on the other side to balance it because this little
clamp if it's like that it's at an angle it's just gonna squirt this piece right out the side so you
want this to be straight and the way you do that is by putting another piece at the same thickness
on the other side and now it keeps it straight so that's one way of keeping this balanced
and sometimes you do need to get creative to make sure the piece is clamped well but that's just you
need to really really make sure that it's not going to go anywhere because even if it moves a
little bit it could jam up on the blade and throw it somewhere so that's that's this tool it's it's
super useful just make sure not to use it on any crazy hard metals and obviously when you're done
make sure to grab a vacuum and vacuum it up and then you're good to go thanks for watching
