  • Hey guys salut welcome back to the croissant

  • series, this episode is all about making a

  • version 2 of the dough sheeter aka the croissant dough flattening machine,

  • now my machine behind me is in pieces,

  • happens to the best of us,

  • just because I wanted to address the wobbly / not centred roller situation.

  • Le me show you what I mean.

  • So initially my axis were inserted like so, using this, and

  • now this is the new system that I am using,

  • the axis are definitely more parallel and better centred...

  • I mean that's what I thought initially and then I checked.

  • Ah, meh !

  • But it's better !

  • The traction still has improved a lot and that's gonna be super useful for the next step

  • let me just my machine back together and I'll tell you more about this.

  • Churros, Donuts, Croissants...

  • Okay so first of all I want to connect the bottom roller with this : The tray.

  • I have a very simple solution, i just hope it's gonna work.

  • I am gonna use a string to do that

  • you see as the bottom roller is spinning, it's also gonna be winding up a super strong string

  • that will be attached right there.

  • And theoretically, if I were to replicate the same system but reversed on the other side

  • I should have a pretty strong connection between this tray and this axis

  • The bond is going to be strong !

  • Now if you are worried about the solidity of my mechanism,

  • if you're worried that the littles pieces of string might snap,

  • Don't be.

  • I am using fishing lines that is initially made for sharks.

  • In fact there is so much strength that I have got a top roller problem now...

  • Let's just imagine for a second that this is our piece of croissant dough

  • So, as this piece of dough is approaching the rollers,

  • Instead of being crushed in,

  • it's being pushed away from the rollers.

  • That problem at the moment is related to the fact that the top roller is just spinning freely

  • It shouldn't spin freely, in fact it should be driven by the bottom roller

  • They should be connected and spin at the exact same speed...

  • Gears !

  • Basically, I printed a gear pattern that I think is right for my machine.

  • I glued it on a piece of plywood, and now I am trying to cut out the teeth.

  • Main problem is probably related to the consistency in between those teeth...

  • Take a look at this one, definitely squared.

  • Curved.

  • This one is like a surfing wave, a swell... a swell !

  • It's never going to work.

  • Gears have a very specific way of meshing with one another

  • So I guess I need to come up with a better solution than just this...

  • Instead of messing around, I have made a 3D model of the gear that I need

  • Then I am going to send this file to a friend of mine who's head of a Fablab at the Paris

  • University La sorbonne

  • His name is Adel and basically we're gonna carve those gears together

  • Hey Adel ! What's up

  • It's so big in here...

  • Laser machine !

  • I need one of these !

  • I need this

  • So you are gonna print them like,

  • In what like plywood ?

  • So we have like

  • Plywood there !

  • Just have to cut it now

  • Okay let's cut it !

  • So this is the result I have got.

  • Way more consistent, way more thorough

  • than the thing I did in my shop...

  • it's a bit embarrassing to be honest.

  • Bu luckily for me, this

  • should work.

  • Merci Adel ! So much !

  • Any time.

  • - Salut ! - See you

  • Right !

  • So I have got two gears to connect the main rollers

  • Plus one gear to perform a gear

  • reduction, let's install all this

  • on the machine.

  • 3, 2, 1...

  • The Dough sheeter version 2.0905

  • It's hard to believe that this is my job.

  • This is actually my job !

  • With my power drill I am driving a smaller gear that meshes up

  • with a bigger gear, the one from the bottom roller.

  • It's directly connected to the one from the top,

  • roller, so those are spinning in opposite directions but,

  • synchronously !

  • I made myself two little blocks,

  • One here, and one on this side

  • Just to prevent the machine going like

  • bonkers.

  • I am gonna clean the whole thing up and then give it a proper test using

  • Croissant Dough !

  • 6mm in thickness which is the end thickness you want for this basic dough

  • Not the laminated dough though,

  • which needs to be at 4mm

  • So this one is always a bit thicker.

  • [French: Lethal]

  • It's so sick !

  • Right, it's now time to form the dough sandwich

  • If you don't know what I mean you just need to watch episode number 2

  • The result at the moment is extremely even.

  • I am gonna wrap it up. Place it in the fridge to chill

  • And then, we'll start flattening this dough.

  • I am starting at 14mm this time

  • and then, I am gonna go all the way down to 6

  • And that my friend is called a double fold.

  • Following the technique that I have learned at Utopie bakery

  • I am gonna make a slit.

  • This is releasing some tension, and it allows butter to go all the way to the edge.

  • I am super pleased with this machine so far !

  • This time it's not about any sandwich any more, it's about laminating that dough.

  • I need to bring this dough all the way down to 4mm and that's

  • and that's extremely complicated to do manually with a rolling pin.

  • Now this machine should just outperform the human

  • Artificial intelligence right there !

  • Proper, smooth and even...

  • I know it's hard to believe that there are 12 layers embedded

  • within this 4mm piece of dough

  • But as a fact, there are 12 layers.

  • And I am a happy man.

  • Now as much as I love laminated dough, those even layers

  • That dough sheeter version 2 wasn't made to make croissant dough but to make croissant.

  • I am not gonna bake one but I am gonna shape one, so that you can see

  • One of the amazing benefits, of using such a machine.

  • 1, 2, 3, 4, 5, 6, 7. Just checking.

  • And the reason why I was able to reach that number right here and not in episode 2 is because

  • The dough is thinner, it's more even and so the croissant just

  • folds on itself just smoothly and more evenly, and that's how I get this.

  • It smells like victory. I mean, not yet. But still, I am on my way.

  • Well I am gonna call it myself, if you allow me, this is a resounding success

  • That machine works, simply works,

  • And so my lamination problems are not problems any more, they are just strengths

  • I can laminate a proper croissant dough.

  • Of course, my journey is not over yet, since I want to complete, I want to perfect,

  • The Ultimate Croissant... I am not sure you hear

  • supermarket butter when I say ultimate croissant, did you ? no !

  • No ! No ! There is no great croissant

  • without great butter in the first place.

  • I need to source the best butter I can get my hands on

  • We all knew this day would come, and mmh... It's next Saturday.

  • bye bye ! Salut !
