    Made a knock box

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Today I made a knock box using PVC piping. *Materials cost a mere $10. *

    However, some idiot knocked into the back of my parked car, while I was shopping in Bunnings, and did not have the decency to leave a note. *

    I am horribly upset!!

    Sadie,

    Well sidestep the ambiguity here. *;)

    Its kind of a small bin with a bar across it. You use it to "knock" the spent coffee puck from the portafilter. I realised the importance of one after filling the kitchen sink full of dents to achieve the same thing. *:-/

    Sadie welcome to CS!

    Sadie when in a Café you see the Barista puting the ground coffee into a thing that looks like a shallow cup with a long handle on it(PortaFilter/Groupcup), the Barista will engage the espresso machine to pump watrer throught this cup that has little hols in the bottom of it (The liquid as you may already know is the coffee you drink) Once this process is completed the used coffee grinds in that PortaFilter/Groupcup need to be removed, once this cup is removed from the Espresso machine it is turned upside down and gently knocked on a little bar that lays across a box, the grounds fall into the box and the Barista is then ready to add more fresh grinds into the cup for another espresso, well Sadie that box that you knock the cup on is the Knock box. Hope this explains well enough... someone else might be able to do this better than me.

    Sunbeam do an excellent knock box or they call it a "Bang Bang" it costs about $35.
    Its rubber top and bottom and the body is cast aluminium.

    The best designed knock box there is for home use. Most are just a plastic pipe with a wooden bar on top.

    Re: Made a knock box

    This is the home made version. 100mm PVC water pipe fittings (90mm is cheaper, but bigger gives better stability). The pair is a threaded end fitting and a screw cap, or inspection cap. The lid has four protrusion jutting out so tradesmen can use a flat lever to crank the cap off. I ground them off so its more stable. Then glued a piece of old windcheater to the bottom so it wouldnt scratch.

    I used dowel for the knock bar, but in retrospect, a square profile would have been easier to fit. I cut the dowel off on the angle and then used a hacksaw to cut slots out of the PVC. Finished off with some liquid nails to hold the dowel in and then a quick coat of paint to reduce the industrial impact, voi la!!

    Heres mine. *If you line it with used bread plastic bags, you can simply pull out the bag once you are ready to dispose of the ground. *

    The picture is only 78KB and since it is a reference to another web site there isnt much CS can do with it.

    Complain to Telstra about the lack of ADSL in smaller/rural areas. It is one major impediment to me moving out of the city. >:(

    Too right Wired, :-/

    Our company relies on our home-based employees being able to work via DSL connections. Got some folks who only live about 40kms from Melbourne, good old Telstra promised to roll out the cable. I had a laugh! That was over 12 months ago.

    Telstra being the kind-hearted souls that they are will only increase supply based on paid-up demand. :-X

    Also if youre more than about 3kms from your nearest exchange they say that DSL aint going to happen anyway. Go figure they can put Satellite phones out in the middle of whoop-whoop yet they cant improve on their basic services.

    Apologies in advance to any Telstra employees out there who may be members of this forum. ;)

    Re: Made a knock box

    Franjae,
    You probably have already triedthis but for others without much practice of pictures on the web, I have done the following and it seems to work well.
    Firstly within the photo software on your PC you maybe able to resize the photo, look in the help section for resizing or batch processes.

    Secondly, if you host the photo at photobucket.com, once the photo is loaded, you can go back in and edit it and resize it to 75%, 50% or 25% .

    Just a suggestion

    Cheers

    Boris.

    Re: Made a knock box

    Heres another el-cheapo home made knock box to add to the list. I wanted something that wouldnt look "too" crappy on the bench so I modified this $6 SS canister and fitted a bolt with clear hose over it. I glued some rubber on the bottom & cut 2 notches into the lid so it would still fit. All up, under $10. Works well and holds quite a few pucks.

    Very clever use of domestic materials to good effect, aesthetic too.

    Does the Imat/nemox/quauha combi have an inbuilt knock drawer?
