>> [Background noise] And now we're going to put
on a new piece of paper and try something a little different.
This compass -- notice you've gone --
you've changed size quite a bit.
Let's look at those --
let's just look at those in comparison.
So we've gone to a rather larger compass automatically,
but you'll notice there's some similarities in this one.
I'll go ahead and take this -- put this one aside.
Just remember this one had a pointed end, and a tracing wheel
and an adjustment, a circular adjustment that got it
out as wide as we could get it.
Okay. This one also has a very pointed end; be careful.
But I'm going to try to tilt this
to where the camera can see it.
If you'll look at this tracing wheel,
notice it looks different; it looks finer.
And let me see if I can get that other one just as a comparison.
Let's see if the camera can see both of them.
Now, you might -- I want you to look at that.
You might think one is better than the other, but I want to --
I just want to show you the difference there
and what's going to happen.
Okay, so now again this one, it's not in the center,
it's a little bit off to the side, but I can --
right now I'm trying to get it as wide as I can.
And my gosh, I think I may be getting it too wide in the sense
that I don't know if I want it any wider than that,
but so far look at this.
I probably don't want it any wider at least for this paper,
but I haven't even gotten to the complete width.
Now let's see, just because I did it for the other one;
let's see how wide we could get this one.
So if you had the need for making a circle this big
and you had something a little larger to put on it,
maybe you just need to make a particular arc --
you could do it.
I mean it is much -- it is much wider.
But we're going to go back and stick back
to a little bit more normal size there if I can get that --
I've never even investigated to see how wide we could get that,
but that was pretty wide.
So I'm going to zip this back and now we're going
to try the same thing with this compass and I'm going to try
to put it about as wide as we had that other one.
I think that's going to still be a little wider.
Okay, so we're going to stab the paper again and if you're --
what you're going to notice is I'm again not applying,
I don't think, too much pressure.
And I don't know if you can see that from a distance,
but it's there and if I turn it
over we've got a pretty good figure.
Now right now, I don't know if you can see this any better
than the other one, but I'm going
to apply just a little more pressure
to this one -- not too much though.
I think I'm a little afraid
because I have perforated paper with this one before.
So we're going to try another concentric circle and again,
I'm going to probably apply just a little more pressure,
but try not to put too much.
I think that's because this one, I feel like you don't have
to put as much pressure on it.
And so I think I'm kind
of backing off a little bit from it.
Okay, so we've got that circle and then I'm going to go ahead
and do another smaller one.
Right there, boy you could --
I think you could tell right there I'm really --
I'm not really applying much pressure
but I think what happens is the smaller the circle that it's --
this one's very easy to start getting it
to perforating the paper.
But I've definitely had students perforate the paper
with this one if they have too heavy a touch.
Now that being said, so many
of my students do prefer the Howe Press compass.
Don't -- you can't ask me, "Well is it because it fits
in their hand better or whatever"
because to me this looks rather large and
yet I had a young lady very petite who was examining all
of these compasses that I'm showing you and she said,
"I like this one best."
I couldn't' see what she was holding onto at the moment.
So imagine this was off of the picture and she was saying,
"I like this compass best because it fits
so beautifully in my hand."
And so I thought for sure she was talking about the APH one
because it was smaller; I mean she had delicate hands,
and here she comes up with this one.
So don't be fooled that you think a --
just because you have small hands
that you can't use this compass.
She -- the small-handed person preferred the larger compass.
So it's whatever the students prefer.
