    By the way, what are you doing these days mate? Finished the masters?
    yeah pretty much. converted to a DPsych though and just have some minor revisions to make on my thesis.
    how u goin at cafenatics? tell us about the mistral...
    and yeah i have to agree that although the robur e is nice in some respects, eg, giving you one more hand as it doses up shots for you, i preferred the more manual control. thwacking is good for the soul. and spekaing of which, i loved the dosing lever on the bnz as well. real sweet

    1) I think the steps on the BNZs are too large. Dennis, perhaps you should modify your grinders to be stepless? Youll love the extra control over the grinder. Are yours conicals?
    Hi David and yes theyre conicals. Before I consider making them stepless theres a little tweak Id like to do to the group heads on the Elektra. Im getting great temp stability due to the restrictors I put into the heat exchangers, but Im still not 100% happy with the flow rate through the heads where there are another set of restrictors. So the plan is to convert the .9mm restrictors in the heads down to .6s to calm the flow down. It can be never ending cant it! ;D

    Once thats done I might do what youve suggested to the BNZs, and maybe even mod one of them to doserless, as per Hazels mod....

    Most of the time the Robur-E delivers a precise enough dose in a perfect mound. Two collapses mid way through the dose delivery and a simple tamp and polish
    Yeah sames.

    I have to say, this grinder really gives me the s**ts though. In fact, I hate it. I prefer the control I have over a dosered Robur. Thats another story.
    Yeah sames ;D Im glad we have both Robur-e & Robur dosered. There was some charge to put the "e" as the main grinder, that didnt last long

    Interesting discussion guys! One that pops up every now and again and one that always gets me revisiting my dosing and distribution technique. This will forever be an evolving process as there is no right or wrong. Its a very grey area with many barista subscribing to many a different technique.

    My dosing, distribution and tamping technique has really not changed for the last 2 years, however now that I have to work with a Robur-E, things have changed slightly. Most of the time the Robur-E delivers a precise enough dose in a perfect mound. Two collapses mid way through the dose delivery and a simple tamp and polish. I have to say, this grinder really gives me the s**ts though. In fact, I hate it. I prefer the control I have over a dosered Robur. Thats another story.

    No fuss dosing, distribution and tamping? Im all for it as long as the results in the cup are good. I simply (haha, not that simple) dial in the grind and dose appropriate for the coffee I am using (tasting and watching each dial in shot to determine whether to simply adjust grind or change dose & grind - this takes a fair bit of experience to know what to do and how to do it, unfortunately there is no text book to teach you these things, its just one of those things that comes with pulling shots everyday). After the dial in of dose and grind, a simple strike off (south to north) and medium pressure tamp (optional lift slightly, low pressure tamp and polish). If I find consistent flaws in my pucks, I will use the Stockfleths distribution technique.

    Sidenote:
    1) I think the steps on the BNZs are too large. Dennis, perhaps you should modify your grinders to be stepless? Youll love the extra control over the grinder. Are yours conicals?

    2) Im pretty sure Gwilym Davies used an Anfim Super Caimano and not Compak K10 WBC.

    3) I did not actually put a PID on David Makins grinder. I pulled the damn thing apart, rewired the whole thing (2 grinders in total) and installed a digital timer. Two very different controllers. PID is a control systems controller used for control-loop feedback such as temperature or pressure, the other is also used in control systems but basically just controls a set of relays based on input and output mode. By the way, what are you doing these days mate? Finished the masters?

    Cheers,

    Dave S

    dave seng (wushoes) hooked up a pid to create a timed dose on Makins that he used at the world barista comps.

    My Lord

    They are bigns Den... Ive never heard of them before. Had a quick look on their website and from the limited info available there, they do appear to be impressive. Very reminiscent of La San Marcos top end grinders in some ways... 8-)

    Honking big grinders Mal - drop grinds dead centre and beautiful stepped adjustment, and look like this...
    A very apt description, it makes my Macap look puny by comparison ;D

    we just swapped out our mazzer major for a BNZ, god i love this thing.
    i dose 8gs from a full dose chamber, we only use double baskets so 16g per shot. collapse once onto the bench, tamp medium pressure, tap basket lightly to release grounds and tamp again lightly, twist to finish.

    hmm, havent read most of this yet, but after having using/playing with the Robur-e at work, Ive found you can pretty much set the programmed dose,  let it grind into the basket, collapse and straight up tamp it and get a great pour (thats with the Synesso). Being a doserless grinder, theres no real need/reason to strike off especially if youve pre-programmed the dose, and no real distribution either, ala "Stephen Morrissey WBC 08 style".
    Gwilym Davies (WBC 09) was using a dosered K10 (i think) and I dont believe there was any distribution.

    Thwack, thwack, thwack......tamp
