  • 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...

  • 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.
