Hi, I'm Ishaan, I'm Lena and we're part of Team USA
And today we're going to talk to you about how to make a linear slides
So linear slides can be used for lifting in different types of linear motion
And today we're going to show you how to build this out of the parts that are included in the REV system kit
Now we're going to talk to you about some of the parts that you'll need to put together these linear sides
We have these 2 420 millimeter long rev extrusions and you can use any length of extrusion that you would like
We have the pulley kit that comes with the first global kit along with the linear motion kit that comes with the first global kit
Ok, you're also going to need surgical tubing string
two millimeter allen wrenches and hex nut drivers and it's important when you're
Using these linear motion kits that you don't mix up the parts
These are single slide on single side slides, which will go on the outsides of your rev rails
Double-sided slides which will go in between your rev rails. There's two different kinds of nuts
Nylock and regular nuts. We also have low profile screws and hex head screws in the pulley kit
So you'll need the small pulley bearings that come with the rev kit along with all the parts in the pulley
Kit, which is the end caps and the pulley holders along with 16 millimeter m3 screws and 4 m3 lock nuts
We're going to talk to you about how to use the double sided slides and
So what we're gonna do is we're gonna put double-sided slides on the two pieces of rev rail and on opposite ends
and then we're going to put the sides together like
And to assemble your double-sided slide you're going to need first this black piece and you're also going to need normal
hex nuts not the locking hex nuts and these
Low-profile screws, so you'll see on this piece. There are two different sides and on one side
the holes are hexagonal and
on the other side the holes are circular and so on the circular side you want to put in your low-profile screw and
On the other side you want to put in?
Your nut and you want to tighten them
loosely
Keeping in mind that you may have to tighten or loosen these in order to get this piece to slide onto the rev rail
And you will also want to repeat that for the other side. So another
Screw on the circular side and another nut on the hexagonal side
Then you're gonna take your Rev rail and you're going to slide on
This piece
See it sometimes you might get stuck and that's because your screw is either too loose or too tight. So you have to
Try to either tighten or loosen so that your
Piece will slide on to the Rev rail, then you want to tighten it
Just until you feel a little bit of resistance
Don't tighten it too much or this black piece will Bend and you will have a lot of friction on your slides
All right, and now we're going to repeat that process for the other bearing on this side
Now that these two bearings are in
what you can do is you can have them lined up so that one of the bearings is at one end and one of the
bearings is at the other end and
Now you have to just align it up so that the bearings go into the other piece of rev rail
If you don't tighten them enough these bearings will often slide between the pieces
But if you over tighten them you will get a lot of friction between the pieces
So you need to make sure that you tighten them enough so that you feel a little bit of resistance
but you don't over tighten them in order to bend the
bearings
All right
Now that we have the slides moving
One of the problems that you might have is that they like to wobble side to side a little bit
and so we're going to add these side one-sided slides to the
Rev rail in order to help support the extrusion from side to side
All right, so there are two sides to this piece there's a side that's written has ridges and there's a side that's flat
So you want to take your six millimeter hex heads and you want to put the head on the side that has a ridge. Um
We put these in and
This is what it's going to slide into the rough rails then on the other side. You want to take these nylock nuts and
attach the screws in place
So you'll see on these this set of slides that we've already started to assemble that there is one side
that is attached to the
The bearing in the middle and then there's one side that moves independently
so you'll want to take these the screws are gonna go on the side that um doesn't move with relative to
the
Double slide and you will slide this on to your read rails
You might have to loosen or tighten
based on how well it slides on and
Then you'll want to tighten these
But not too much and you will have to play around with the tightness
To make sure that they're tight enough to stay on to the rail but not too tight as to produce lots of friction
And you'll want to do that again with the other piece so find the side with ridges
put in your screws
Attach your nuts
This time go to the other side of your linear slides you'll see this time. This is the rail that's moving independently, so
Okay, if you have mix inside of your Rev rails on the sides you might have a little bit more friction and you can hear
like a grinding noise
So if that's the case you may have to replace your extrusion or loosen or tighten these screws
But ideally it should look something like this, which is a very very smooth motion and it's a very strong linear slide
That doesn't wiggle as much
So you might have noticed that very frequently these slides will come apart
and so in order to stop that from happening, we're going to use these eight millimeter hex head screws to
Prevent the rails from sliding apart. So you want to take the rail that is moving and you want to put in your
Screw your nut
Hop that all the way at the end of the rail and tighten it onto your rails
And then you'll also want to adjust the position of your single side slide
To match so that the rails match
And
Then you're going to repeat that on the other end
So this is the slide that moves here and
Then just
Adjust the position of the single side slide
You see that these rails now
Now we're gonna show you how to
Make the linear slide to move using a motor
so if you use the Kevlar string that's included in the kit and
You attach the string to a motor and as you pull the string
The slides will extend and so we're going to show you how to show you it on the bigger set of slides. So
This first step of this is attaching your end cap. So you'll want to take the slide that stationary
so this one and you'll want to attach your end cap on to that and
Using a screw screw it in so you'll have to thread the piece of Rev
so just
It may take a little bit of extra force to tighten the screw and center of the revolution
But once you've done that it should screw in and out oh
You need a 16 millimeter screw to do this, yes
Okay, next we're going to take another 16 millimeter screw and put it
Inside this end cap and
this is going to be used to attach the
Pulley, so you want to take your pulley and your piece of Kevlar string?
run the string around the pulley and then stick the pulley into
The pulley holder and then you want to
Stick it onto your screw
And with this nut you need to be careful not to over-tighten
Again, because if you over tighten it there's some the additional friction on the pulley
And then on the other end of your slides
You're going to put an 8 millimeter screw
So it if you don't turn it enough it will fall out like that
So make sure that you tighten it enough, but don't over tighten it
And
Here, we have a bowline knot that you can look up how to make
And you'll want to put this around the screw down here
Hold this tight
The Rope should not or kevlar should not come out now when you pull on the string
In order to reduce the friction on the pulley is rotate this part and if you get it, right
It should slide and rotate pretty smoothly
Another thing you might want to do is add a washer right here to prevent the string from coming loose
So now that we've got in the sights to go up we need to figure out how to get them to go down
How to use either
All right, so the first thing we're going to do is prepare this bracket
this bracket will help us mop the motor you can see I've used already three screws and nuts to just
these will allow us to
slide the bracket onto the right of being
Can't even do this
All right, so now we're going to slide the bracket so that the flat side is on the
opposite side of the spring so it's going to slide in like this and
So that will allow us to
Alright now that it's tight in what we're gonna do is we're going to take our motor
Screws one of these holds it doesn't really matter which one I'm gonna touch with sideways that way. It doesn't hit the ground
Just use a millimeter hex head screws to attach
And first loosely screwing all of the screws that way the motor gets aligned and then
And then once you're done loosely tightening them tighten them all the way
You want to make sure that this mounting is tight because otherwise
Now that we have that we're going to
Mount something that we can pull the string with so we're gonna start out with using a hex shop
And in order to tighten these acts of colors you'll need the one millimeter
hex
allen wrench and
Then we're gonna put this shaft through the motor on the other side
And now prevent the shaft from sliding around and on this side
we're gonna use a high-strength hub and the reason why we're using a high-strength hub is because it will help reinforce our
Pulley, which is this piece and you can use any size pulley. We pick the size because we wanted something that would go faster
So now I'm going to
Tie this to the pulley and I took it off because it's a little bit easier to tie when it's off the motor
so first you're gonna try to get the shrink through and
You might have to use an Allen wrench to push it through but ones that comes up
It's nice
and then what we're gonna do is we're going to have this part of the shrink go down the pulley and
Then we're going to wrap the end of the string
Around once more and put it into the next hole
So
Like this it's pushing through that way we create some friction and prevent
The
This piece of string from coming off of the pulley and now we can tie it off using
square knot to this piece
This pull and it should stay on the center of the pulley
The reason why we use such a big pulley is because it would take less wraps of
The pulley to lift this entire system up
Which means that the string wouldn't overlap on itself and have a potential to fall off of this pulley
so now I'm going to put the pulley back on to the
hex shaft on there and now when the motor rotates
It goes up and when the motor stops rotating
It'll come down due to gravity
All right
Now that you've made this linear side
You can use it for something you could attach like a claw to lift and lower game elements
You could use it to lift the fuel cubes or power line cubes
