    Double Tamper --- Twice the fun?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    This weekend I made my own tamper... christened the "Double Tamper" because it has a tamp on each end.

    The single and double baskets on the BoEma are slightly different in diameter so a double ended tamp seemed the logical choice.




    Features:

    Created from a single piece of billet aluminium and turned-down on a manual lathe it is both functional and attractive.

    One end is square (err... flat) and the other is slightly convex. Giving the best of both worlds.

    The groove in the middle fits my fingers and the non-tamp end cups in the palm of my hand well.

    The taper at the base of the tamp lines-up accurately with the top lip of the basket if the right amount of coffee is added. This acts as a great consistency guage.

    Total (post turning) weight is 500g making it a joy to use.

    I can recommend others have a crack at making (or at least designing) their own tamper. Nothing bests a one-off custom built to fit.

    I look forward to seeing pictures of other peoples designs ;D

    Most impressive!

    Have you ever made a standard type of tamper?

    One of my tampers has a taper that corresponds to a correct dose, its a really handy feature.

    A few times Ive thought about alternate designs for tamper handles and taps or corkscrews have come to mind. I think either the T-bar style or the old school X style tap came to mind because I tend to polish a fair bit at the end of the tamp.

    T or an X handle... interesting thought although it then makes it at least two parts.

    I guess the retro version would use an old hot water tap X handle?

    Man - that looks excellent!

    How much did the tamper set you back Andy? Im not really a "making things" kinda guy, but would like to know how you actually made it? Is it some sort of lathe?

    Re: Double Tamper --- Twice the fun?

    Thanks Andy. Yeah it was made on a dodgy old manual lathe.

    The "lump" of aluminium was bought from a local supplier, 200mm long x 60mm diameter and cost $28

    I only used about 120mm and because I have a lathe in the shed, cost me only time to make it.

    There are some great tampers on the market at really good prices but if you wanted to design the "one off" yourself then visit a local engineering workshop, Im sure they would turn one up for you for not a lot of money.

    There is always something special about your own Tamper.... We to made some out of Aust Hardwoods and they were great, but there were inherent problems with them.. (splitting from the heat of the machines if left on top and also grain direction).

    Ill take a photo of our Brass Beast for you later to see as well.....

    Andy... Lathe Work is a lot of fun isnt it..Time consuming too, but you get some great results if you persists and with your Tamper, this is a prime example.

    well done!

    I really like the sound of your brass one. Seems like a great choice of material and look forward to seeing the pictures (if only to inspire others to look outside the box). :)

    I remember seeing a guy at a car show electroplating things in 24ct gold... might be a nice finish to an alloy or brass tamp.

    Andy,
    Ill stand behind AndyCJ if youre offering ;D, I have tried locally but as soon as a I mention one off the little shops dont want to know :(. I dont have a lathe, nor the skill to operate one, and Im too tight fisted to order one from the most popular tamper maker around (I saw one at Eds place on the weekend, and they do look great). Anything the correct diameter is going to work better than the plastic job supplied with the Silvia.

    Good job.

    Boris.

    Sure I can make you one Boris, 2 hours at $100 per hour plus material plus postage.... $250 should cover it ;D

    If you cannot guess... Im not really interested in making them but maybe the one-off is a problem with the workshops.

    If there was enough interest in Silvia sized tampers then I could get a local engineer to knock-up a batch of them or maybe just the right sized base and people can get creative with their own handles?

    Re: Double Tamper --- Twice the fun?

    Here lies he problem Boris and ACJ.... doing tamper like this is really a pain if you have to do it as a one off.... The setting up on its own is bad enough and what if you are off with your measurements....... This is why sopecail ampers like this are not so common, its either doit yourself or the I know a friend that has a fair bit of time thing.....
    I actually cociderd a while back buying a metal lathe, but didnt go ahead with it because this too would become a time filler and time is a bit hard to get a hold of lately.
    If you have a Technical colledge near by, Use the right words and see what they might be able to do for you.... just a thought.

    Cheers

    Hi guys,

    Nice to finally join the community Ive heard so much about!

    Ive got a lathe as some of you would already know, and Im not opposed to the idea of doing one-offs for people if you want something original, and dont like the ones already on my website (I wont get offended! :)) Ive also got industry contacts who can do larger batches if one design proved particularly popular.

    Let me know your thoughts!

    Regards,
    Greg

    Welcome Greg, its good have you along...

    Im not sure if youve checked it out already but it seems like people here really dig on the tampers you make! They look unreal.

    Love your work,

    Let me tell you people, I got a Pullman tamper for my new Silvia a couple of weeks ago. It is nothing short of sensational. The service from Greg was beyond all expectations. It seems that the Silvia basket is getting being made a little narrower than before and Greg took the tamper back to shave off .3mm for a perfect fit, which he did overnight. I really recommend that you send in your basket to him so he can make one up perfectly. It is worth the effort. This fellow should be supported. For the relatively small amount he charges for his masterpieces, he must be doing it for the love of it.

    Damn... www.patent.... www.protectmydesign... www.tamper-mafia...

    I make one dodgy "double tamper" and the Tamper Mafia appear in the middle of my post. ;D

    Welcome aboard Greg, lets see if we cant get a few new designs for you to look at.

    One modification I would suggest for your tampers would be to turn some shallow "depth lines" on the side of the tamp. I found the taper on mine is a really great way of keeping consistant and even the missus is making better shots now.

    ;)

    Hey dont let me steal your work! :) Just thought from "If you cannot guess... Im not really interested in making them but maybe the one-off is a problem with the workshops." you werent interested. I dont mind taking on a bit, but just hope not everyone comes running with their own designs now! :o

    The depth lines have been suggested before and I think theyre a good idea. Ill see what I can do about adding them in. How many do you think would be necessary - 3, evenly spaced between top and bottom? I guess they only need to be ever so shallow, just enough to make a mark on the side?

    Yeah I guess so. Because I was making one for myself I just tapered the "foot" at the depth I wanted.

    I assume that if you are making them the same width for a few different models of basket then 3 or 4 lines on the side should cover most baskets.

    I can see a time in the future where baristas will say "I tamped to 3 on the Pullman tamp" ;D

    (or maybe no one will ever want one?) ???

    No worries, Ill see what I can do. I think the ideas got a lot of merit, which really shows the value of these forums. End-user feedback is something I value and which cant be underestimated for its importance (sorry if that sounded corny! :)). Keep the good ideas coming!

    Hey Greg!

    Your new checkerboard handles rock mate ;D

    Im working on the wife for a new one. I ordered a 57mm from you a few months ago and have since upgraded to a Silvia. So expect a post from me up the track for a 58mm checkerboard. Gotta have one :P

    Hey Warren,

    Glad you like the look, dont mind them myself. They take more work and moolah to make, but theres hardly any out there so far so theyre definately the way to stand out from the crowd!

    Hi Greg

    Im not sure how I havent bought one of your tampers yet. My fiance thought there was something phallic going on with the handles when I showed her some photos of your work, but maybe that is something she will have to learn to live with :)
    The grooves seem like a great idea. Are they deep enough that ground coffee would get stuck in them? Only concern and not a big one.
    Im sure in part that this is where the whole groove thing started, but Ill mention it anyway. The depth of the base on one of my tampers roughly correspondes with the top of the basket when well dosed and tamped, which is really handy. Ive got three other tamps and I miss this feature when I use them. The new groovey tamper may solve this small issue.
    Have you found it useful yourself?

    Nice work Greg,
    That was pretty much what I had in mind. All of the worlds owners of the GP Tampers will now have to upgrade to the new and improved tamp depth metering model because their "classic tamp" has just been outdated.

    I hope this model will be christened "The CoffeeSnob" ;)

    Re: Double Tamper --- Twice the fun?

    sharkboy: I suspect theres a chance coffee will get stuck in the grooves. Unfortunately the only way to get around that is to make the grooves a lot shallower, and I found it was too hard to see them when they were that shallow. When youre making 100 espressos an hour, you dont want to be messing around with catching the thing in light to be able to see the rings! But then, if the tampers a proper fit, chances of coffee getting up that high are largely minimised anyway.

    In some cases the top of the vertical face of the tamper (where it meets the outside chamfer) lines up with the top of the basket, and this makes it easy for people to get it level. That was part of the design, but obviously this varies on your exact basket style, load volume, tamping weight, and also whether youre using a single or double basket. This was also one criticism levelled at the RB tampers - the base was too thin and that corner was well below the top of the basket to be able to get it level. Hopefully now, no matter what you load and how hard you tamp, youll find it easier to get an even pack.

    Andy: Good stuff. I guess the proof of the product will be when you guys start playing around with them, but from the tests Ive done they certainly help.

    Ahhhh BUGGER!
    Now Ill have to get another tamper ;)

    Looks good Greg. Im considering another handle and basket at present. if I end up getting one, you might have a basket arrive for a fitting.

    ;D ;D ;D ... looks like Brett is first cab off the rank in the "my old tamp doesnt cut it anymore".

    ...and after the "Chicken on a stick" sucker episode I feel much better ;)
