Project Coffee Fix - new.
groupsck...@dfgh.net
I'd like to improve the coffee supply in London Hackspace. Most important aim is to be able to get a decent espresso. To begin with a few simple things.
- getting a coffee tamper (probably make it - design is on page see below)
- trying to have espresso coffee available somehow (even if that just means going to a shop)
- trying to repair an old machine I will bring in
What I'd really like to get is a decent coffee grinder (burr mill of some kind) if someone has a suggestion where/how to get one that would be great.
Project page, together with design for a tamper is here.

I don't really have enough knowledge or even motivation for other things people might think we're missing like cold brew coffee, but if anyone else is then we could work together to fix more stuff.
all the best

I have tended to be the one that cleans and fixes the Gaggia Classic we have, but have become a bit jaded and couldn't be bothered to do it for a while. It really needs the case being fixed and some TLC but I've been away.
The biggest issue is that from what I can see, a lot of the people who use it don't care for it. This ranges from just not cleaning out the portafilter after use, to having a dirty and empty reservoir.
What coffee machine were you thinking of bringing in?
There is also a UNIC grinder on eBay (Same as a Macap) that used to be £40 but they have evidently just changed to auction only.

It should have 58mm burrs and be quite decent for hackspace use and should be fairly cheap. Alternatively I have 4 commercial grinders at home I could part with, but they are all more expensive pieces.

I can also get a coffee/espresso machine, but I only have my discount for the next week and a half, before my last day, and I don't know what would be good to have and they can be a bit pricey for me to foot the whole bill for, depending on the model.

I believe the Gaggia Classic is still the 'spaces best option for coffee machine, but it really needs more care to be taken by the current users.
Considering the space is having issues with a bombproof Gaggia Classic, any other domestic machine is likely to suffer the same fate quicker.
A Sage smart grinder would work acceptably, but my concern is that they are a bit too plasticy to survive the hackspace, and for the same price a second hand commercial grinder would be cheaper and better.

So the Coffee Fix page has it's first achievement. I put a handle on the lid (see photos https://wiki.london.hackspace.org.uk/view/Project:Coffee_fix ) - better progress than many abandoned projects :-)
Answers to everybody's questions/comments/offers below.

Have you tried the coffee roasters (square mile coffee ?) on Emma Street ?
Not sure if this is a personal project or a group request, but if you want help I may be able to assist.
I'd love help and other people involved. If nobody helps I will do what I do.

The solenoid valve thats vents into the drip tray doesn't seem to be as good as it should be, but didn't have my tools with me to investigate further (Ironic that the workshop downstairs doesn't have basic tools). It's on the list of thing to do.
The pump is getting abused because of filth in the water reservoir. One of the internal ball valves gets intermittently jammed, so I stripped and cleaned it again. This will need replacing if the problem continues.
I've placed a plastic tamper inside the donations box. It is 56mm, and we really need a 58mm, but it's a start.
Most of the grinders I have available are big, with a footprint larger than the coffee machine itself. I'm not sure the kitchen can handle such room being used by coffee gear? Open for debate...
The Gaggia Baby Class D is a more electronic version of the Classic, but the internals are basically the same. I would be interested to have a look at it and am confident with most repairs if you need assistance? I should be available a lot next week.

Probably also be in on thursday, approx 10->12. I'd definitely appreciate some cooperation with the fix. I did fix this machine before and it had problems with solder joints on the main circuit board. I think it's something electronic related to that, though there may be other/multiple problems.
All the best
