    Re: Greg Pullman Tamper

    Have been considering one of these for a while, but I dont want to part with my baskets while theyre being measured etc. Does anyone think its neccesary to send them in, I have a silvia with stock baskets...

      Well, I have a stock standard Silvia and I just ordered the tamper without sending the baskets in.
      My tamper fits fine, but there is always a slight risk that your baskets might have a slight variation.

      Rather than send your basket/s in, another option is to take your baskets to a hardware store, or someone who has access to a measuring tool called a vernier caliper - as mentioned on his web site:
      http://www.coffeetamper.com.au/FAQ.htm#ExactMeasurement
      and send Greg the exact measurements.

        I didnt have to send mine in, as I could pick my machine from a dropdown list. As a precautionary measure, I did measure my PF and gave him the measurements.

        Besides, youll only be out of it for a few days anyway. You might have to use *cough* a plunger.

          I think you should be alright with silvia, i used the verniers and gave Greg the measuremts (so do that if you can). it fits perfectly! although it does sometimes stick slightly in the LM basket i received a while back (obviously not Gregs fault).
          As a side note, i was curious to the difference this tamper was going to make.... believe me it is huge!! especially from the thing provided with silvia.
          Very happy with the purchase and the service Greg gave leading up to his holidays before christmas. Great effort

            Couldnt you use the single portafilter whilst it is on holiday?

                or you can also buy a spare basket ... considering that a LM double basket is $7 + postage (Im too lazy to drive to Roseberry).

                Once youve got your basket back, you can drill a small hole in the spare, a hole small enough for a k-type thermocouple...

                  Speaking of thermocouples, very interested in getting that kind of setup too.

                  Ive ran some tests with a multi-meter and k-type probe, but instead of doing any modding I just ran the probe wire through one of the portafilter spouts. At that point the water had already gone through the coffee puck and basket, so perhaps making the readings misleading...

                  Will open another thread for this anyways

                      Re: Greg Pullman Tamper

                      Will someone put me out of my missery. One of you good folks did at some time post a pic of a leaver operated tamping machine. For the love of searching I cannot find the pic. So if you have a pic or know of a supplier of these devices can someone please let me know the details.

                      This thread is interesting as there is much discussion on tamp pressure. It is elusive isnt it? I mean what works for one doesnt work for another witness the 2 baristas. The grind, the tamp and the type of filter all interact to make crema. I tried using a open Krups basket abit at first it seemed ok but one time I had to make a lot of essence so changed over to the Sunbeam double only to find that i got more crema.

                      Use of the double basket for a single shot is good in that the volume of grind that fills the basket to the top is the quantity i use. When this is tamped it goes some way down the basket, about 4mm. Repeating this process gives me repeatability as I do the same grind. The shot usually runs 15 to 20 sec. The shorter the shot the more creamy the coffee.

                      I have found that my tamp pressure does vary inspite of my trying to make it the same. I have looked at those clickers and whilst they would do the job if used carefully i want gay abandonment as Im usually talking whilst making a brew and some times the need for concentration is lost in the banter.

                      Whilst picking up an early breakfast latte this morning from my local coffee shop I watched the female barista as she alone behind the counter proceeded to serve 5 of us all in the same time frame. She had the whole process off pat. She was fully in sync with the process producing one great brew after the other. I couldnt resist it I just had to say well done. She smiled back and said "know about coffee do you?" Just a little i replied as she proceed to use the doser and then take the portafilter up to the fixed tamp.

                      Now here is where it gets interesting. You see she was woking flat out, arms and legs and torso going at a great rate. Poetry in motion really. But then the tamp pressure was nothing more than a quick upward movement of the portafilter agaist the fixed tamp plate. The pressure at a guess would be no more that 6 to 8lbs. Basiclly she was just tidying up the grind in the PF.

                      Like I said poetry in motion and customer service at its best but was she getting maximum extraction? Lest face it we pay for a coffee, right, if we only get half the extraction and this makes for a great brew and the grind gets thrown out who cares? If on the other hand there is a greater extraction then this will of course change the result. A different taste noless.

                      Hence when i arrive for a coffee the first thing i look for is who is the barista driving the machine then I order the cofffee.

                      5 minutes later im checking emails and sipping on a great brew. So what is all the controversy over tamp pressure?

                      If necessary it would be very simple to build a machine to give the pressure one needed, adjustable at that, so that the same personal pressure can be applied every time. It is possible that there are such machines out there hence my request for pics and a supplier. If not then maybe ill retire and make them.

                      When does this journey stop?

                      It keeps the grey cells active and thats for sure.

                        Try MACAP automatic lever tamp.

                          This is such an interesting area to experiment in....A friend once told me that Giancarlo Giusti of Grinders never used to tamp- just simply fill the basket and lock in and run....So I tried it....

                          What I found is that if I load consistently the effect of no tamp versus 30kg (i.e over the top tamp) amounts to no more than 1/2 notch on a standard commercial grinder to maintain a consistent, high quality pour....

                          I still tamp and teach 15kg, but I think that accuracy and repeatability of dose is way more important...

                          Try it...you may be surprised

                            Great one Chis. It is such an interesting subject and becuase of "new found knowledge and the unsatisfying thurst for knowledge I find it very entertaining to watch a barista at work. Just as back up in this thread theres the story of 2 baristas at work with the same machine, and im sure in the commercial world there must be a zillion of these. Each to their own as long as we get consistancy. It comes down to taste taste and still more taste. Said many times on this site.

                            This girl was a work of art and most certainly a credit to her boss who at that early hour was still in bed!!! What I liked was when she broke the ice by saying "you know about coffee do you?" Then the smile on her face as if she had got recognition and she had. Her brew was obviously enjoyed as the customers kept coming and she kept dancing.

                            Now all things considered not withstanding coffee knowledge and the whole journey etc she is in my book a Barista...a maker of fine coffee.

                            Thanks for the suggestion re no tamp i shall try this just to see what happens. 15kg well thats around 33lbs still a fair pressure.

                            Thanks MattG for the reference i took a look and decided I didnt want a second job!!! Nice piece of kit but hey the price. I have an idea to make one using a touque wrench so ill play around this weekend.

                            Thanks guys
                            Still having fun

                              Remember espresso is just someones idea of how coffee should be so dont be afraid to experiment to get your coffee to your own taste.

                              A light tamp is becoming common in places like Italy evidently, just enough to get most of the air out of the coffee and make it pour properly.

                              I probably use the standard pressure but I know people here too who tamp lightly.

                              People also have their ideas on volumes to use. Most CSers tend to ristrettos but a lot of people use higher than standard volumes.

                                wow this is an old thread, and im sure this has been discussed in a more recent one but i couldnt be bothered to look for it.
                                anywho, in my limited experience of fixed tampers,(i worked in a cafe that had one, but promptly brought my own tamper in after about 2 shifts!) they are less effective for a number of reasons,
                                1. your applying upwards pressure which is harder to control than downwards
                                2. the tamps are far from fitted, normally well smaller than your basket
                                3. because your not resting the portafilter on anything, its harder to get an even tamp, applying excess pressure to one side.

                                ive found my coffee to be exponentially better when i tamp user my tamper and watching over the tamp.
