    Burr orientation on vintage La Marzocco?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi,

    I intend to replace the burrs on my vintage La Marzocco Vulcano (pictured to the left). The machine currently has the burrs pictured with the blades running to the right from the outside; I assume this to be "right-hand rotation" blades.





    Looking from the top, the motor rotates in a clockwise direction. Id just like confirmation that the blades are the correct orientation for the rotation of the motor before ordering a new set. Information on this model is essentially non-existent.

    Thanks and regards,
    Phil

    Thank you Thundergod for saving me from having to ask the same questions. :D

    Phil, Thundergod is right - phone Coffee Parts in the morning.

    Hi Phil,

    From what I know about this grinder, its relatively old and, as you say, quite rare. Pedro might know, but if he doesnt, you might want to contact LM directly. I gather that a lot of their grinders were manufactured by conti valerio srl, who manufacture the nuova simonelli grinders, too, so perhaps it will take a NS burr set. The holes look to be similar in orientation to the mazzer burrs, so you might be able to use a set of them, too.

    Hope that helps,

    Luca

    Hi Gang,

    Thanks for the responses thus far. I do plan to phone our Aussie supplier of parts, but I have learnt as a domestic consumer to have a wee bit of a knowledge base to avoid being treated with disdain.

    Luca, as you mention they share similar specs with Mazzers et al; 64mm OD, 37mm ID & at least 8.5mm thickness. What I am less sure of is orientation....it seems to me that the grounds have a better chance of being expelled cleanly if the burrs were facing the other way. I did spend a bit of time "Brasso-ing" the chromed brass chute to minimise drag while I have the grinder dismantled. I f I hit a brick wall, indeed LM theselves may have an answer...apparently they have a Vulcano in their museum! The Swift burrs are in the opposite direction; Id love to use them in this grinder.

    Thor and Viviane,

    The Espresso machine is a humdrum home-grown product, a Bo-Ema. Its probably a little hard to recognise with the "pillowing" of the SS which I did myself. It transforms a SS and painted box to something approaching attractive! I bought it as a basket case and restored it . One of these days, I plan to describe the resto. here with photos. It was a fair bit of work, but Im stoked with the result and the performance. I must add that Bo-Emas spare parts service is second-to-none IMHO; like I mentioned earlier however, he doesnt suffer fools gladly.

    The warning sticker was my idea of a wacky jape. There was a deep scratch there which couldnt be polished out, and as my eye cast around for something to cover the scratch, it alighted on the sticker that was lying nearby. Its not that unsafe, I swear!

    Kind regards,
    Phil

    Hey Phil,

    If youre in Victoria, Id be more than happy to organise to see if some mazzer 64mm burrs will fit in, in exchange for getting a chance to see this piece of history in the flesh!

    Cheers,

    Luca

    Dont knock the Bo-Ema, from what Ive read of them I may have been tempted to get one instead of my Expobar if I had run across them earlier.

    Youve done a good job adding some bling, though I dont think the Bo-Emas look too bad anyway.
    Nice bling.

    The warning sticker appeals to my sense of humour too.

    I got in touch with Coffee Parts and had a good chat. Just for your information and the archives, a machine that has a motor rotating clockwise uses right hand rotation burrs (also known as DX).

    Luca, thanks for the offer of a try-out with the Mazzers (which is what I ended up ordering), but I am in Sydney town. If ever youre in the vicinity however, youre welcome to check it out! Pedro was interested in it also; while its in pieces, Ill take a heap of photos and post them here. I should email the photos to Paul Pratt in HK...hes the only source of information that Ive found on the net, and hed probably like to see the gubbins.

    Hey, dont get me wrong, I love my Bo-Ema! It uses the same group head as a Bezzera I have here, so guess where they source that from?! It sports a nice big chromed copper boiler, rotary vane pump, and all the other specs that youd expect with a commercial machine. It took me a while to dial in the boiler and group pressure I like, but Im now reasonably happy with what Im producing. Anyway, its probably OT for the grinder forum, now Ive got my feet wet I must post something about it in the appropriate forum.

    Regards,
    Phil
