Hey guys, salut, this is Alex, welcome back to the
croissant series, in this vid I'm gonna build a
brand new version of my dough sheeter. And there are
two reasons for this.
So, reason number one: that tool is possibly the most
tool when you're making croissant dough, apart of course
from the oven, which might be the first one, or
the fridge, which might be the second one, so
it would be the third most important tool - what do you want?
And the second reason, which is a little more sad, the
previous dough sheeter machine that I built in episode 4 of the croissant series
has been damaged, it's basically f---ed up.
--snare shot--
Due to it's rennovation, it's been shaken
it's been moved. It's not working properly anymore.
And that's... not only bad to be honest.
Since this machine had quite a few problems
in the first place--I did struggle a lot inserting those
axis in the center of the rodding pins
and now it makes the precision... basically not precise.
That is way too much friction. Also!
This machine is just too big. It's just using this, but
I could make it more compact, but then the other problem
would just remain the same, so
nah.
So as I recently got myself a 3D
printer, I thought maybe I could use that to my
advantage. So I made a 3D model of
a first design... let me show it to you.
So I kept a few things from the previous design, I kept the gears. I also kept
the rotating thickness adjustment
system, but I changed the
moving tray mechanism, I'm not using
a wire anymore I'm just using racks and pinions.
Obviously a new design also comes with
new problems. First of all the curve right there is not
accurate. Also its base on-axis,
which means that I need to insert them perfectly perpendicular.
But these are just tiny problems
regarding this (motions to screen). That bar is here
to make sure that those two driving gears will move
synchronously and will make the tray move back
and forth in an efficient, smooth and
parallel manner.
It also comes with the
DUMBEST mistake ever.
THIS bar is totally in the way.
The dough can't get to the rolling pin
unless it's flatter than ....
9.2 millimeters.
I made a flattening machine that only accepts
already flattened dough.
-slaps knee-
I'm gonna address these problems, but one by one.
-upbeat music and assorted sounds of tools-
The rolling pin itself, it's not a rolling pin in the first place.
It's a table leg which I
went for just because it's amazing diameter.
Problem is--it is wobbly on itself,
like there is at least 2-3 millimeters
variations in height.
When you're working with a 4mm dough, it just makes like
for 50 percent accuracy.
-wizz, pop sounds-
So instead of going for a complicated solution
like buying a lathe
-sawing sounds-
Turning myself
-more sawing-
a perfectly round
I'm gonna use a rolling pin
I had this one for a while in my studio--it's perfectly round
and perfectly straight. Of course it's promising if...
I can manage to connect this perfectly
perpendicularly to my machine.
I got something.
-energetic electronic music plays-
So this is the part that I just designed.
So it connects to the rolling pin like so:
Which means that it's automatically and perfectly centered.
Then it's going to be secured using four screws. Right there.
That's great because instead of transmitting the torque
to the axis, I'm gonna directly transmit it to the
key. And that's great news but it also means
that I need to do another design because this would definitely
not fit in what you just saw. So lets start again.
-assorted sounds of getting down to work-
(Advertisement for Skillshare)
Truth is, I've been working on a new design
Hopefully it's much better. Let me run you through it.
And then I'll just assemble all the parts.
So overall it's more compact and making good use of the gears you just saw.
There's a driving axis which is not in the way anymore, and that's good
And the tray is now on top of the driving pinion and that's great.
So to adjust the thickness,
it works the same, you spin the whole arm like this
and to set it in place basically you use a little pin
it just blocks the system in one setting.
Now those two pieces are connected, like when the tray is moving then
the gears are spinning.
They can't move without one another
So I guess I got everything I need, I'm going to print all these parts on my 3D printer
OK, let's do this!
-upbeat swing music-
Looks very promising
It looks solid, it feels solid
Let's give it a try with the bearings
I need plywood!
Lots of plywood!
-upbeat swing music continues-
I think I've got all the parts that I need to build at least
like a proof-of-concept.
Side arm. Driving gear. Rolling pin gear. X bolt.
That just seals the whole thing.
Waaaay!
This is very exciting.
You've got this part which is very important. It's a rack.
And so when I turn this...
-3 delayed marimba hits-
Awwwwww
Ahhhhhh --crying-- Ahhhhh
--yelling and focing the gears together--
Worst engineer ever.
--censored cursing in French--
Let me show you why I'm saying m----
So when the tray moves forward, basically this is
spinning clockwise, and it should be spinning counter-clockwise
in order to suck the dough in, not to just...
If I were to add another gear inside
just to reverse the rotation of this big gear
then I would increase the friction
If I were just to place the tray underneath,
when the big rolling pin gear goes down it would crush
the rack, used with the pinion to-to-to make the tray--
Okay! I got a solution: let's stop everything for the day.
Let's just have a bite, let's call it a day
and see tomorrow what I think of this.
Okay
We'll see us in the morning.
-door closes-
Well...
I think I got something
I think I'm gonna put the tray underneath the driving gear
and I know that I mentioned that the big rolling pin gear
was gonna crush the rack if I were to do this
Well, let me introduce you to what I call:
The bobbin gear.
it's very similar to the first rolling pin gear that I
made earlier but now--
you've got a groove right there
and that groove just
allows you not to crush the rack
and yet to be connected properly to the rolling pin
and to flatten the dough.
I think this is the key to-to-to my machine.
Let me print just a few more parts
And do a little sewing action, put everything back together
And then hopefully we should get a machine--wish me luck!
-hopeful sounding music-
Tense moment
I'm just putting the finest screws to my contraption
Hoping everything will run smoothly.
-determined music continues-
-piano music starts-
Back... and forth...
-celebrates-
So I would say that compared to my previous machine
So much of an improvement, it's so compact.
I love how accurate the new settings are.
Also it's just more obvious
there's less friction, it's more efficient
It's probably like a twentieth of the original size.
A twentieth!
"Twonteeth"
I just gave it a test with some proper dough
And I'm really really pleased with the results so far
It's really great, I mean it really does the job.
It's so compact
So I guess this is another step on
completing the perfect, ultimate, French croissant
By the way I will share all the files with you
in the description box down below.
I'm gonna give this machine a proper use
on another dish--something I've been working on
for quite a while--it's not a croissant. It's something else.
So guys, that's it I hope you enjoyed this video.
I hope you enjoyed this machine. Like, Share
Spread, Sub, you know what you gotta do.
Take care, bye bye. Salud.
