I say is a big day we're going to build the prototype version. 4 of the Liberator, the compressed earth. Brick press behind me is go type version 3, so we've never built this machine before no one's ever built this machine before we just finished designing it.

A

Marcin has built previous versions of it, and a lot of a lot of the same procedures were carrying forward so we're using his wisdom to assist in those processes. I've been building up for this I've been looking forward to this for months now, summary I'm excited it's going to be fun day.

A

A

They just come.

B

Look right here: we've got a drill, I think it's three quarter-inch bolt holes through two pieces of steel that are clamped together right now, and so this has to be very precise. We can't have any vibration, so if the hole is bigger than it needs to be, it's going to vibrate this.

A

Is an ironworker machine? It's a hydraulic power cheer, so it takes two very hard pieces of steel and rubs them together like a pair of scissors, and it cheers two pieces of metal and half.

C

So we're putting this right through this hole, it's gonna make a really.

C

Torch this precisely with for one take more time today, we're just punching also the the troubleshooting. If your hole is imprecise, you'll have to do a lot more work, just trying to get things to fit together. Thirty two point: one: three: minus twenty: five one: three or seven inches. So that's the distance between this hole and that hole. That's exactly what this should be. It is exactly seven inches.

D

If you like people heat it up the size about, you, have those two are mountain of shopping entire, face at custom. Catfish like that and put it together your life. Now it's one piece, one solitude.

E

E

Okay, so we have a single package of documentation that we're all using obey, not all using the same parts we're using different parts that are associated with different parts of the CV press that were each making. We have the entire set of fabrication drawings for the CV press on this document.

E

Now we're editing a Google spreadsheet collaboratively, as you can see, there's right now for other people working on this, we're recording our insights, so the insightful information that each of us learns from doing these processes now in retrospect or even during the operation, can record them so that future operations are that much easier and error-free challenges.

A

Include getting getting stuff to fit tight that needed to fit tight today, we should see or standing.

A

Try to put a percentage on it, I, don't know I'd, say we'll cross the 50% mark and like to see I'd like to see a food tomorrow, not positive. That's like it again tomorrow.

C

A

You guys mount the hopper I can work on the mounting the cylinder, but.

B

It's totally within reach.

A

E

A

Totally within remit right here we have the main structural core with the outer structural arms right now, gobby is mounting the hopper interface saddle. That's a new design for version 4. The hopper is going to sit inside of there. Let's go look at the hopper, it's going to be the hopper, as you can see the other CV behind me to see how the hopper sits on top and collects the soil. That interface saddle that Gabby's working on is what holds this. This sits inside of that saddle.

A

We also have the great it's a different shape than version 3. We got narrower for geometric reasons is the shaker, and this is this- is a t-shaped head of a hammer that will move in and out and that hammer is just going to pound against the hopper shake soil down through the funnel into the chamber where bricks are pressed.

A

Smaller though kitchen yeah.

A

I've been looking at this machine for months now, you know.

A

And to actually see it in real life, it's hard to realize that it's separate like need to take a little time to myself, breathe realize what's really been done,.
