- Let's take a look at what came with this servo.
First of all it comes with these little rubber things,
these are called servo mounting grommets, okay?
And if you look closely, you can see
that they're pretty much round all away across,
but on end there's a little part
where it's got a little square indentation,
and that's the part that goes out.
So the round part, it goes in,
and you just plug it right in here,
theoretically, c'mon, go in there, there we go.
And you'll notice that the little square part
is sticking out right there.
That helps alignment.
So I'll put those in.
These are traditionally used to
avoid vibration from RC motors and stuff,
but I see no reason not to use them
because there's a lot of times where
if you have a remote control head with 18.
We've had one of the Predator heads
that Richard Landon built for Predator 2,
had forty-two servos in it.
So you can imagine that there was a little bit of vibration
happening from those servos.
So this just kind of helps
deaden those down a little bit.
So let me get that in there, there we go.
Alright so there is the servo
with the little grommets on it.
And then as you take a look here, on the table,
there's these little brass inserts, okay?
And these little brass inserts go inside the hole,
and these are to keep you from over tightening
the little grommets.
And of course, the nice thing is that these little servos
come with these little wood screws that are used for it.
And what they are is, they go in through the bottom,
so that the flat flange part is gonna to be the part
that goes up against the wood.
Unless you're gonna to mount them upside down,
then you would put them on the top.
So, I'll go ahead and put this in here.
There we go.
And I'll put the other one here.
If I can get it in.
There we go.
And that way, the screws go into them,
through the top.
And they allow you to create pressure and set them in
without crushing the grommets.
Also, if you start crushing the the grommets,
it starts to make the servos get a little off kilter
like this, so, it's better.
So I like using them.
I know some people wonder about if you use these grommets,
if there's going to be too much flex
in the servo going back and forth.
And I've never really had that problem.
So that seems to be okay.
Alright so I'm going to go ahead and put this guy in here.
And then I will grab
a pencil so I can make little marks
so where I can make the drill.
So alright, here we go.
Alright so I'm just going to go in here,
get that lined up where I want it.
And there we go.
Of course I need to see my little pencil marks.
I'm going to get these started
with my automatic center punch here.
And I've dialed it down so that it's not--
You know if you dial it all the way in here
and so this is gonna be like a really,
intense hard hole
but to make it a little bit lighter I'll go ahead
and dial it down like that.
And so then I'll just
go ahead and...
Here we go.
Get it right over the mark.
(metal punching through)
And once again over here as well.
(metal punching through)
Okay.
Now just grab a drill.
(drilling)
Alright.
Alright so here goes one.
(loud drilling)
And here goes number two.
(loud drilling)
Alright.
Okay so (blows) blow that off real quick.
And I'll throw my servo on the floor
because that's the Craig test,
to see if that survives.
And I'll go ahead and put this in here again.
And I'll start one of these.
I have a little Philips head so that's good.
Okay I started one.
And I'll go the other side and start the other side.
I wanna like usually,
I wanna get both of these screws started
before making,
making one permanent because
there's always the case that
if I can tighten one down it might misalign the other one.
So here we go, is one.
And you can get 'em pretty tight too
because that little brass sleeve in there
allows you to do this without crushing the grommet.
Alright, there we go.
There's a servo attached.
And I'm gonna go ahead and...
Put the other horn on here that I'm gonna use.
And I'll just so all I had to do to do that
is, there we go,
once again the servo itself has a Philips head.
And I'll take the little screw out.
And you'll notice that there's a little,
this one comes with a little, oops.
Here we go.
You can see right on the end,
there's a little tiny--
I'm not sure what these kind of washers are.
My viewing group, what kind of washer is this?
For extra points.
It's got the little star inside of it.
I'm not sure what kind of washer it's called
but call in and let me know (laughing).
Alright so I'm gonna remove this one.
And there you can see the little metal gear head.
Now this isn't the only metal gear inside this servo,
although that they really help.
Some of these
if it doesn't say metal gear or MG or something else
this might be actually made of nylon.
And when you're pushing heavy loads
I've seen cases where these nylon gears have stripped out.
Also on the inside there's, inside there's also
a little gear arrangement of several other gears
that attach this gear to the actual motor
and those are also made out of metal as well.
So alright.
So let me grab my...
Little servo tester.
And I'll plug this guy in so I can center 'em.
- [Man] Chris Eloby thinks that's a lock washer,
you were showing.
- [Craig] That makes sense, yes, thank you.
- [Man] Put it at lock washer.
- [Craig] I think it's a lock washer.
You were right.
Alright so I put this on the center
so now the servo center
so I can unplug it.
And I'm fairly happy with where that is.
Alright so and for now
I'm gonna stick this straight up and down.
I'm not sure where it's final resting place will be
but for now I'm just going to leave it at that.
- [Man] Oh an actually, Mark Wolf says it's a star washer.
- Okay.
- [Man] And Mike Nocky says
that it's an internal star washer.
- That even makes more sense.
Because the star is on the inside.
- [Man] And now Brian says
that it's an internal or an external tooth lock washer.
- (laughs) Awesome.
- [Man] Star washer, it's a lock washer,
it's a tooth lock washer, it's whatever you need it to be.
- [Craig] It's funny because most of those describe
the washer itself too.
Alright so there it is.
Um, so there is that.
This is going to be the other eyebrow servo.
And at this point I'm gonna take a look
at um--
Okay I'm gonna set this aside for a second
and I'm gonna go back here and look at
at my five minute epoxy
which is a little, it's still not complete cured
but it is hardened.
It's a little bit on the sticky side
but that's okay.
I'm not gonna to do this one first.
I'm going to do the one that I did yesterday
that's already set up.
