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.

基礎受動態

Now this was built by Kay's Vander Vestal.

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

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

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.

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

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.
