  • when you walk into the reception square mile.

  • One of the first things you see on the shelving is this, which is an espresso machine, and it is by far the scariest was weird and wonderful espresso machine I have ever owned.

  • Now this was built by Kay's Vander Vestal.

  • You'll know him from buildings, spirit, things like speeds toe.

  • He builds really beautiful stuff on.

  • There was an auction, and he donated this machine to the auction.

  • I bought it in that auction on Dhe.

  • It is a fully function coffee machine.

  • I want to show it to you because one it's really cool.

  • And two, it's a really interesting explanation for how espresso machines work because everything is completely exposed.

  • And that's really scary.

  • You can really see how a simple E 61 style espresso machine works have plumbing works.

  • What does what?

  • So this hasn't run like five years, so we need to do a little bit of TLC to this to get it running, so we're gonna clean it up.

  • This is dusty on.

  • Then we're gonna work out what needs doing to it.

  • It's missing some parts.

  • We'll see if we can get running we see if we can pull some shots with it on.

  • Um, yeah, this is this is that machine.

  • Oh, Most importantly, this thing was built in 13 hours from scratch, and he used a bicycle that he found in, like, a skip out the back off his building.

  • And it still has the bell on the bicycle.

  • How good is that?

  • All right, John, you clean this up and they're going to assess what parts we need to get plumbed in, running on making some coffee, so that's a little bit clean.

  • It's not the easiest thing to claim in the world, but most of the dust is gone.

  • Some of it's just ugly, and that's kind of its charm.

  • It's never gonna be beautiful unless you stripped it completely to pieces and power threatened something better.

  • We're just never gonna do that to this.

  • Now, when it comes to these things, the first thing you want to do is make sure that you have your hydraulic sorted.

  • We will make sure there is a supply of water to the machine.

  • The water is covering elements before we turn it on.

  • So right now it's a bit bare bones Now there's a water inlet here just threaded and let which we can put a braided hose onto that will come from the pump.

  • Which other seemed to have.

  • I'm actually in the past.

  • What I've done is I've put a quick connect on the pub control cable.

  • This is the thing that the powers that pump to pump on when you wanted to come on s o.

  • I need to find a pump pump head.

  • I need to wire it up on.

  • Then I need to find a couple of braided hoses on connected to a cold water line and then, you know, we're getting there.

  • So I found an old son s a pump in the workshop.

  • I'm gonna be able to just repurpose this army to change some parts and fittings here, but that's not really a problem wired up.

  • And we should be good to go.

  • A distinct lack of compression.

  • It compresses.

  • That's water in done.

  • Now, because this is gonna be a quick set up.

  • I'm just gonna put Sir John Geste straight in there to supply with water as quickly as possible.

  • Now, don't judge me.

  • This is just a really quick and dirty setup.

  • This is nothing like I would do for, like, an actual installation.

  • This is just a quick I can bench test didn't play with it comes set up.

  • So you got some pushback coming in and then just switched a few parts around, and then we have water go out to the machine.

  • So this would be our next challenge, which is the quick connector that used to run to a pump that I have long since lost saying cut this off and then just hardwired into the old center.

  • So pumping is dead, and that should be good to go.

  • So we've got some water in here now, so we're ready to turn it on.

  • But we need one more thing.

  • Something missing up here now at the back of the machine is actually a space for a light bulb When that light bulb will go on any time, the element is heating.

  • So, uh, I need a level.

  • Okay.

  • It's starting to get hot.

  • Now start.

  • Get some pressure building on the steam boiler, and I should try and explain why I have a white tub here.

  • Now, this machine is awesome, but the drip tray leaves a little to be desired.

  • It is just a piece of mesh that has no connection to any sort of waste.

  • So you need to put something under it to catch anything that you want to run out of script.

  • Now, this machine needed a good flush through.

  • It had been a while since I've seen fresh water.

  • So that's kind of a thing on, then, what we could do.

  • It's gonna walk through the kind of hydraulic pathway off this machine.

  • I hope to try and explain how it works.

  • Now, before I do that, I should probably explain the controls, which are a little bit unconventional.

  • Okay, so everything is run from this thing here on this thing activates these two little switches here.

  • When you first push, you'll activate this switch on.

  • All it does is essentially start pre infusion.

  • By opening, the group had solemn I'd just sort of over here.

  • Uh, it's hard to see that will allow any line pressure coming from your your water mains to come through the machine and just drip out of the group head when you pushed out enough to contact the second switch.

  • That's what kicks on the pump.

  • So you have kind of a two stage infusion here.

  • So if we go stage one, you hear that click?

  • Got some dripping from the group head on.

  • Then come goes on.

  • So you have to hold it down to make the pump runs there, hold it down the whole shot.

  • So that's what's going on here.

  • Now, this is an old E 61 star thing here.

  • So what you've got is one cheap coming out of the top of the heat exchanger running along into the back off the group head there that cheap underneath it, running down, away, down, back into the bottom off the boiler, the heat exchanger.

  • Now that is a thermos open so that hot water can also be drawn off here to go through the little, uh, switch here to the group head to make coffee.

  • So these things kind of stable ish, but you often need to flush them to sort of stabilize that temperatures go temperature surfing on dual boiler machines Now don't really need that NCR steam pressure there.

  • That's basically what controls the whole machine.

  • It's not the most accurate way to do temperature, but its's thing that works.

  • You've got essentially a relay controlling the power, going to the element from the thermostat.

  • And then he got power going to either.

  • The pump bore to a solemn vow to open and close it.

  • Now, one of the reasons this machine is just so terrifying is that it's really hot, like all of the hot bits are exposed.

  • This it's very easy to burn yourself on this, which is why I could never really be used by anyone except me.

  • Problem may.

  • So one of the most terrifying things about this machine is probably this valve here, which is a manual fill valve to fill the steam boiler.

  • You're gonna keep an eye on your psych class to make sure you got enough water in there at all times.

  • Esteem is pretty simple.

  • Comes out of the top of the steam boiler into a valve, which you just control in the normal way on DDE dramatic steam.

  • So there's nothing else really left to do.

  • Pull some shots.

  • I need to get a grinder and some coffee and some caps and all that good stuff on.

  • Meanwhile, I'll tell you about this video sponsor, which is squarespace whenever I need to build a website by a domain, I use squarespace, whether it's a website to showcase the world atlas of coffee or a portfolio for me to share what it is that I do for a living.

  • Squarespace is fantastic.

  • Software to build that website with their fantastic templates, cover a whole range of needs that you might have for a website.

  • It might be like me that you're showcasing a portfolio, but it might be that you want to build a website for your cafe or your restaurant using these templates.

  • It's incredibly easy to customize them.

  • Tow.

  • Have those sites look exactly how you want, but you have the reassurance in peace of mind that that website will look great across any browser and any device.

  • But you should find out for yourself, signed up for a free trial and build a website when you're ready to launch, used the Lincoln my description or use the code James Hoffman and you can get 10% off any domain or website purchase.

  • Thanks to square space for sponsoring this video.

  • I guess that's pull a shot.

  • All right, go the Big 20 Grand Moose, Mass.

  • A little bit's getting messy day coffee in.

  • We're gonna pull by pre infusing until we get those first few drops of coffee.

  • It's a big dose.

  • It's gonna take a little while.

  • That assumes we see that saturation happen.

  • Crank up the pressure.

  • We had coffee.

  • It was pretty good.

  • That is pretty good.

  • So there is.

  • This is by far the weirdest, wildest, most terrifying coffee machine that I owned.

  • But this was interesting that this was fun.

  • I don't really know what to do with this.

  • Just it's a beautiful ornament.

  • It's a terrifying espresso machine.

  • So this is probably the last time.

  • In a good, long while it'll make coffee, which is a shame.

  • Anyway, this was fun.

  • I had fun.

  • Thanks so much for watching.
