- Well howdy there, come on in
to the Laramy-K Optician Works Dance Studio.
Grab a beer, grab a partner and were gonna learn
how to do the high curve two step
( dramatic upbeat music )
Hello.
I would like to welcome you to the Laramie Kay optician
works training center,
where today we have a very special guest with us.
This is Jason Abbott.
He just took over the Atlanta region for Santa Nella,
and he happens to live just a couple of hours away.
So I invited him to the training center.
I had just gotten in this Alexi trend eight,
and we went over some of the features,
but I'm going to let Jason tell you about which.
ones those are.
- The Lexi trend aid is one of our flagship units.
It is available with a drill or without a drill.
This particular unit does not have a drill today,
but that's okay because today John's gonna focus mainly
on telling you about the high curve wheel that's included in
this machine.
- Right and we just spent the day,
I think it's about one o'clock now we started about nine and
we dug into this machine.
We both learned all kinds of cool stuff.
And yet I am going to go ahead and dig in and show you the
high curve feature and the step bevel and how that can make
you a much better optician.
I invited Jason here to the training center. Well,
first of all, because he's new
and he's the rep for our area.
So I wanted to say hello and get to know him.
The other part was I have never had an edger that had these
two features. I thought, wow,
be great to have a Santa Nella guy here.
When I learned about them, two features high curve.
And step bevel.
High curve. It's a feature.
And it's all about the tracer.
It's about the tracers ability to gather spatial awareness.
Can the tracer capture frame curve alone,
or can it capture the frame curve and the frame angle?
Let's take a really quick look at those two ideas are those
two terms, all right, you guys know me?
I never hide anything. I am sure as hell,
not a robotics engineer or designing a
technologically driven equipment.
NASA is not calling me on the phone very much offering me
work or anything. This is my understanding of it.
The frame angle and frame curve terms come from
Santa Nella. Their address,
different companies may very well use.
Different language get into is my take on this, that term,
the numbers that I just showed you frame curve is basically
the curve of the eye wire.
Think of it as the frame base curve,
all of our lenses have a base curve
matches to the back curve.
That bevel think of that curve is just the same concept
carried over to a frame.
It is independent. Eye wire to eye wire,
but kind sorta needless to say,
they're always the same right to left in a given frame.
Now frame angle, we simply think of as well, wrap.
That's all there is to it.
If we think of a frame curve,
we think of it being independent measure,
perhaps from the center of that out,
we have a radius that be correct.
And then for the frame itself, the entire frame angle,
perhaps from the center here capturing that entire curve
( static ) See what happened was in the,
have you had an older machine or do you have a tracer that
doesn't have the capability of tracing a really high curve?
Well, then you traced one.
Eye wire independently,
you turn the frame set it in as printed on those
horizontal style tracers like those right there.
And you just trace one eye wire because it
could never make that curve in that term.
Now turns out that the ability of the tracer to make that
high curve trace and gather all up
information does one thing.
And that is that it does a frame PD or in particular,
a frame DBL compensation when it knows the
full frame angle.
And it's very, very high, a big per heavily wrapped frame.
It does a little fudging on your PD frame PD relationship to
kind of bring this in.
If you put that high curve and you bring it in,
you're in a sense, bringing the PDs closer together.
So it messes with those numbers.
Now, the wicked cool,
really nice to have, make your life
a whole lot easier feature is
this step bevel.
Now all of you are good. Optician works opticians.
It's about reducing the interference between the bevel and
the bezel.
You all know that a lens has a bevel
and the Eye Wire has a bezel.
This basically works best helps you out the most in your
higher minus in your higher curves,
these two can work together and that way,
these are generally your plastic sport frames,
your heavy sunglasses,
your safety's plastic safeties and your anything, plastic,
big, heavy, thick plastic.
It.. it particularly addresses that point right there on the
frame.
Now applying the step bevel to the entire circumference of
the lens is going to make your life easier.
But it tends to be when you're trying to assemble a higher
minus lens in a heavy curve in those big thick plastic,
that that's the area that tends to give you the problem.
Well, it simply boils down to
better finishing work the lens with a step bevel.
And I'm about to show you this finishes better and inserts
into the frame. Much easier,
greatly reduces the amount of heat you need to use for
adjustment. And it stops at splaying out of the temples.
brings them in. And I'll show you this in just a second.
Remember that our edger is always looking to optimize the
frame curve and the lens curve match, or in other words,
the bevel bezel relationship.
That's why when we was talking about, don't try to
make a job fit.
If you have a patrol.. poor base curve frame curve choice,
you can't really override that you can't override it using
base curve changes where you might be able to do it
with a better edger. Let's hit the bench
and look at high curve
just a couple of numbers there. Really.
And then look at what a step bevel looks like little hard to
see, but I'll show you anyway,
- Here is an example.
This is a very
common or generic men's middle frame,
which when traced has a frame curve of 5.7 and a frame angle
of 6.0.
Now when we switched to our heavily wrapped Maui,
Jim sunglass look at the results.
Our frame curve is 4.8 and our frame angle
has jumped to
18.3.
- So. That's high curve.
The ability of the tracer to trace a highly wrapped frame,
feed that information to the software and the software
makes some tweaks to the frame PD.
Now let's take a look at step bevel. Again,
I never had an edger that had that feature, but boy, oh boy,
I sure do wish that I had,
I would have put it to use quite often
- super hard to see here, but here you go.
Anyway, the lens on the lift has
The step bevel lens on the right does not
a much better way of seeing it. If you will,
is from the edge of confirmation display.
This is the bevel profile and the default or no step bevel
setting where this is with a step bevel.
If you caught the opening.
I said, we were going to do the high curve two step.
And there it is, a 0.3 clip off of that corner.
And then the full step or ledge that allows the frame to
clear.
It might not seem like much,
but those two small differences.
Add up to a huge change.
When assembling in adjusting those sport sons and safeties.
( machine noise )
- All right, hot off of the edger.
We have our right lens, which we did not do a step
Bevel on. And the left one that we did do a step bevel on.
Now, I had mentioned that it tends to be this kind of upper
temporal corner that gives you all your trouble.
Obviously the relief of that extra cut-out helps all the way
around the eye wire, but see here.
Yeah. It's going to take some heat to get that going.
- In there. So let's crank that up.
- Okay. And so this is, this is what happens.
It tends to want to kind of hang up right in these corners.
Nope. That's just fighting every inch of the way.
It's the conflict of that bevel ledge back here,
which gives you this little tiny lip out here.
I'm going to try heating up that corner a little bit more.
See if I can get it to pop over it.
( crack noise )
Oh man. Oh man
That is really hard. Okay.
One down. Let's do our left now.
Mm, that's pretty good.
Mm, to our left.
Okay
And that was the one with the step here is the frame in
roughly good standard alignment.
And without lenses
- here is the frame after lens insertion
where the right did not get a step bevel and the left did,
that's it? That is what step bevel is all about.
That is straight off the edger into the frame warmer and
after lens insertion, could you fix it?
Well, Yeah, sure.
But you're gonna to be forcing things.
You're going to use a lot of heat in order to get it right.
So it might make it a little bit clearer.
How much of a difference that that makes.
- All right. ( banjo music ) That is high curve
in step in bevel, two features of the Lexi trend eight.
I truly believe step bevel underutilized.
If you have it by all means experiment with it makes
finishing a whole lot easier. Makes your finished work,
look a whole lot better and most important sets you apart
from your competition.

please give us a like or watching on YouTube.
Please go ahead and hit that subscribe button down there in
the corner and make absolutely certain that every lens that
you're applying high curve and step bevels to come from
Laramy-K
I will see you again.
Next week.
