    Need for new burrs

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I bought a Rancilio MD50 from an auction a little while ago. *I wasnt sure about the burs, but as the grinder didnt appear to have ever been cleaned and the old burs were pretty much welded on to the collars I thought they probably hadnt been changed (the grinder is 9 years old).

    My new burs came the other day thanks to coffeeparts. *there is a definite difference i n the feel to the burs. *the new ones definitely have a sharp edge, not quite like a knife but I you could probably cut your finger on them. *in comparison the old ones are really dull and dont seem to have much of an edge at all. *I have attached a couple of photos below. *photos are a litle overblown but you can see a difference in the edges of the new (which are much cleaner) to the old whiich are a little worn. *Old bur is rusty cause I cleaned it and had decided I wouldnt reuse it so I didnt dry it off properly.

    what i might do when i get time is install the old ones and try and do a direct comparison to see what the difference is to the grind and in the cup if any.

    Re: Need for new burs

    finished product.

    Total cost $225, plus about 30hrs of labour and a1/4 tub of coffeemachine cleaner for soaking all the bits that were gummed up with coffee oils.

    I still need to finish polishing the hopper with plastic polish, I got most of hte haze out of the doser but my arm was getting sore from wax on wax off. I think they had been using steel wool to clean the hopper.

    The doser plastic is looking good now.
    I hope the hopper comes up as good for you.

    Your sig says Mini Mazzer.
    Why the MD50 then?

    Hey, does Greg do vanilla tampers for the MD50?

    Meguiars Plastix polish for car headlights etc, brought it up quite well. *the hopper is alot more scratched up, i think they actually cleaned that, whereas I dont think they cleaned the doser.


    I refurbished a micro cimbali lever photo in next post (are you able to post more than one photo in a reply?), which I was planning on taking into work and wanted to have a dedicated grinder for it. *I thought the cheapest way to get a decent grinder was to get one from an auction. *It cost me $165, then I bought the burrs, a can of enamel and some feet from bunnings (the rancillio ones were $20, only paid $3.90 at bunnings).

    admittedly its a bit of overkill. *the grinder is automatic, every 6 pulls on the lever it starts grinding again, turns itself off when the dosser is full (its a big doser too). *it does seem a bit faster than my mazzer though, but that is probably the 64mm burrs compared to 58mm on the mazzer, I might put them through a race on the weekend to quantify. the motor is also quite torquey, there is a noticeable flex when it starts up.

    Also i think the mazzer looks better, but the rancilio will be at work so it was function over form.

    I was thinking about that. I have one for my expobar and its great. the cimbali i was going to pair it with is a bit of an odd size, 51mm. from the looks of his website i would say it would be relatively easy to fit, the current one just screws through from the top so it should fit, I would probably send Greg the whole protrusion which the tamper would screw into to get him to make it fit neatly. it is relatively small and just unscrews.

    Its never been asked before but thats the sort of installation theyre designed for. So no reason why not providing mounting hardware is compatible.

    Custom stuff can generally be done if the standard Vanilla doesnt go on.

    Yeah, but why would you want a Vanilla tamper when the real deal is under-priced? Ive said it before, and Ill say it again - Greg, put your prices up!

    They went up for the first time in four years about a month ago. Tampers increased by $10, and postage went up by smaller amounts. Are you suggesting theyre still too low? Obviously I have to cover my costs and its handy to have something left over to cover breakages etc, but without sounding corny Im more interested in people having a decent tamper than making heaps of profit per unit. Obviously if its too cheap it suggests its a cheap product but I personally dont think its underpriced at present. Since its not a business, within the above parameter profit isnt the driving force.

    No, Im just saying that your tampers are still quite a bit cheaper than other high-quality imported tampers, so theyre a great deal. I dont think that anyone thinks of them as cheap. Comments from people who have bought them suggest that price is the last thing that they consider. Maybe its more that many of the other high-quality tampers are imported, so there are heaps of additional costs there that you dont incur. Whatever the case, it results in a sensational deal for coffeesnobs! My gut feeling is that they should be around $80, especially if the basket is measured to fit!

    Cheers,

    What? Not even you??! :)

    Particularly for Aussies, I like a local product to come in below that of imports, and the current prices were set with that as a factor. Certainly price doesnt appear to be a significant factor in the decision of most people, but its just as well as Id like people to decide based on need and quality rather than purely available finances. As you suggest, my unit price is just under the unit price of most overseas units but they then have to pay international shipping. Anyway I reckon weve deviated OT slightly here! :)

    Perhaps the word is "excellent value" = cheap, without the bad quality connotations!

    On the one hand, yes, I get that you dont have to ship as much stuff around. On the other hand, you individually craft most of the bases.

    In any case, if youre happy with the price, I dont think that anyone will complain if you dont raise it!

    Hitherto, I think that people have always thought of your tampers as high-quality, handmade products. Maybe my little digression will add underpriced to the list ;P

    You may now return to your regularly scheduled programming.

    Re: Need for new burrs

    Clinto , you did a great job. Whoever had the grinder before you should be slapped with a dead fish for letting it get into such a state. If I saw a grinder in that state in a cafe I know I would walk out again.

    Gregg, I think the price of your Tampers is reasonable. I am on a very tight budget and I can justify $69 + postage to OG especially for something custom made - and very beautiful. Any much more than that and it would be out of my reach.
