Hey all. I bought a Trosser on Ebay this week for $17.90 shipped. I got i= t and it seems to be in pretty good condition. This morning was my first run with it. I turned the grind adjustment lever on the bottom clockwise until it was as tight as I could possibly get it. = I then ground my homeroast (Brazil COE 5th place) for the dose. I tamped it with 30lbs of pressure. I ran the shot and I could tell it wasn't going to be good. Espresso much too early and over 2oz in about 15 seconds. Not a good sign. I did it all again except this time with 40lbs of tamp. Same result. Then I did it one more time with 55lbs of tamp and same result. It's just not grinding fine enough. All 3 pucks revealed one wormhole on top. Is there anything else I can do to make this grind finer? The grind seemed nice and consistent but if this is as fine as it will go I'll have to go back to my Capresso Infinity, which is definitely not ideal but will give m= e a decent shot of espresso. Anyone?! brad |
This is a multi-part message in MIME format. can you adjust it so the burrs just touch the back off a tick. This should chock your machine. RK |
I guess not since I've got it as tight as I can get it and it's still not fine enough. It seems like I should be able to get them that close though. Not sure why I can't. brad On 5/27/06, rnkyle wrote: <Snip> r <Snip> I <Snip> t <Snip> to <Snip> a <Snip> to <Snip> ive <Snip> |
you might back it off a bit, then turn the handle, see if it will close more at a different angle. .. On 5/27/06, b cook wrote: <Snip> h. <Snip> ot <Snip> ver <Snip> I <Snip> t <Snip> to <Snip> a <Snip> on <Snip> to <Snip> ive <Snip> -- Regards, Brett Mason HomeRoast Zassman |
I tore mine apart for a cleaning & adjustment. To adjust: The rotating burr might not be properly cent erred in the stationary burr. Take it apart. Mine had 4 screws in the top, then it lifte= d off. A couple of wood screws hold the bottom burr carrier. You can loosen the wood screws and move the carrier's position. Make sure it's clean, a bi= t of grit in the burrs would make it off center. Tighten the grind adjustment= , wiggle the burr carrier, get it centered. Then screw it down tight, loosen the adjustment a bit, screw it down ... You might also check the thrust washer. Look at the assembly, in the area o= f the adjustment screw. When you adjust the grind you turn a screw, pushing the shaft up or letting it drop down. The shaft has the rotating burr & handle fastened to it. At the bottom of this assembly is a thrust washer. Its a soft steel washer that is at the bottom of the shaft. This is a sacrificial part, designed to wear away saving the shaft & bracket from wea= r . It's possible that somebody added a washer that is too thick as a replacement? That'd limit the minimum adjustment. For a replacement, make sure you get a soft steel washer, it has to be softer than the shaft & bracket so that it will take the wear. No plating o= n this washer! A trace of iron is good for the diet, but some of the other metals wouldn't be a good addition. Just get a plain steel washer, not stainless. If it has been hardened, heat it with a torch then let it slowly cool. --MikeW On 5/27/06, b cook wrote: <Snip> r <Snip> I <Snip> t <Snip> to <Snip> a <Snip> to <Snip> ive <Snip> -- "Life is just one damned thing after another." - Elbert Hubbard |
Thanks for all the tips, Michael. I don't see a washer down there. I see the little handle to turn the screw and between that and the carrier arm is a spring. The rotating burr seems centered when I eyeball it from below as I turn the handle. I thought I had it as tight as possible yesterday but I got out a dish towel so the edges of the adjustment screw handle wouldn't dig into my fingers and I got it even a little tighter...to the point where the burrs sounded like they were rubbing when I turned it. I really had to torque it to get it that close though. Then I backed off a little when I got the burrs to that point. I'll be trying it out again this morning a little later after music practice at church. I'll report back. brad On 5/27/06, Michael Wascher wrote: <Snip> ted <Snip> bit <Snip> nt, <Snip> n <Snip> ing <Snip> ear <Snip> on <Snip> ly <Snip> get <Snip> asn't <Snip> lbs <Snip> and <Snip> ve to <Snip> give <Snip> |
To see the washer you have to disasemble the mechanism. It's at the bottom of the shaft.

I got in a big hurry this morning and after I filled my basket I forgot to tamp and shoved the portafilter and basket up into my machine just as I realized it! The dose was ruined and I didn't have time to work up another (especially with the Trosser) so I'll have to test it tomorrow. brad On 5/28/06, Michael Wascher wrote: <Snip> m <Snip> t out <Snip> nto <Snip> burrs <Snip> e <Snip> the <Snip> lifted <Snip> osen <Snip> , a bit <Snip> stment, <Snip> oosen <Snip> rew, <Snip> ing <Snip> ust <Snip> his is <Snip> from <Snip> s a <Snip> e <Snip> ting on <Snip> her <Snip> t <Snip> slowly <Snip> t <Snip> ibly get <Snip> .

It could be that there is gummed up coffee oils on that shaft. It shouldn't be that hard to turn, and the fact that it will turn with a inordinate amount of force confirms my suspicion. If the burrs were really touching, you wouldn't be able to turn it. I suggest that you try to clean that shaft anyway that you can..I'm thinking a toothbrush and some solvent of your choice... I don't think you need to disassemble the whole unit, but it wouldn't hurt... <Snip> |
And it should be very easy to turn. The burrs are much less aggressive than those on the Zassenhaus. Much easier to turn but it takes many more turns. Disassembly is easy on this unit. And reassembly isn't that hard either. On 5/28/06, Angelo wrote: <Snip> -- "Life is just one damned thing after another." - Elbert Hubbard |
Just to be clear, it's not the grinding handle/shaft that I'm having troubl= e turning. It's the grinding level adjustment handle. So when it's at it's maximum level of fineness I shouldn't be able to turn the center burr at all with the grinding handle? brad On 5/28/06, Michael Wascher wrote: <Snip> |
If I really crank down the adjustment on mine, it won't turn. But you reall= y have to bear down on it ... turning it tighter than seems reasonable. As yo= u tighten the adjustment down it'll be pulling against the stationary portion or the mechanism. The two wood screws will be taking all of the force, and the wood top that they are screwed into isn't all that thick.

Before I engaged my alleged brain, I measured 14g of beans into my large machine for the making of small pieces out of bigger beans. You already kno= w the rest of the story- no amount of tapping and compaction was enough. I meant to grind it at an 18 setting. It took about 3 secods to grind it at 42, and 3 more seconds to realize my mistake... It was not a good demi of Dummkopf espresso. Cheers -RayO, aka Opa! "A mind is a terrible thing to..."
