Very good [smiley=tekst-toppie.gif]
Hi All. Just thought Id share with you my method of finding the right tamp level for any given machine. Its not as precise as the 5 cents test obviously because it wont let you know the correct dose in gms for ground coffee but it will give you the level you should be tamping to.
Its worked for me so far :)
Very good [smiley=tekst-toppie.gif]
Hey, a very similar looking guy already discovered that http://coffeesnobs.com.au/YaBB.pl?num=1315922389/180#180 oh wait.. thats you! ;)
Hehe...yeh. I remember that thread. That was when i came up with the idea. ;D
Hi saoye, can I put this on my blog?
I think its a brilliant thing :)
Nice one saoye,
Will give that a go. :)
Gary at G
Rice one............. :)
Oh, Mono, dont make me hit the Mod delete button for bad puns... ;D
What a great idea, Saoye, love it! [smiley=thumbsup.gif]

Hi Shapeshifter. Yeh no problem. Thats why I shared. Hope it helps. :)
Let me know how you go GG.Originally Posted by 3C262B2A382E363C3C4F0 link=1327631793/5#5 date=1327828628

Ooops......I suppose this is getting off topic now. Seriously, great Idea and I will try it on Junior soon.
Just a heads up for the Rancilio Silvia owners, the 5 cents test does not work for most Silvias because of the protruding hex nut in the middle (unless youve done the modifications to have a flat screen nut - Im not sure if theyve since changed this or not to be standard).
The Rice method WILL work however so its a plus for Silvia owners everywhere :)
Works fine with Silvia, just move the 5 cent piece to one side of the screw. ;)Originally Posted by 77656B7D61040 link=1327631793/11#11 date=1327894031
I guess that makes sense. ;D As long as the level of the tamp was perfectly straight. Being at the peripheral makes it critical to have a perfectly flat tamp or you will get an uneven indentation, but then thats also a good way to show if youre tamping straight or not ;)Originally Posted by 0D31382035540 link=1327631793/12#12 date=1327894855
I tried this and found I was filling the basket a bit too much - great stuff to work out correct level.
I did it again today using cous cous ( iPad wants to call this cows cows) and its even better as the grains are smaller and its easier to fine tune the amount of grains.
I have made a black line on the Pullman at the correct level ( removed the handle and put a 6mm screw into my drill) with a fine* permanent marker: if it works out as good as I think I will post some pics...
Yep, rice or cous cous depending on your diet and wats in the pantry. We dont eat much cous cous so rice it was :) glad it helped u though. Definitely a good quick check. Note make sure the portafilter as well as group head is fully dry. Give them a good wipe with a dry cloth beforehand.
very clever!!!!! :) :)
Awesome, nice idea, will try on Ms Silvia in the mornin
I wonder what 9 bars of pressure and 92 degree water would do to rice?? ;D
Urn, u do understand the test is to be done without pulling the shot itself right? Or is that just a statement of curiosity? Not recommended although I think you will have to run a fair amount of hot water to get it remotely cooked.Originally Posted by 6B73617A7B7C7E73667B74120 link=1327631793/18#18 date=1328368691
I think it was a joke... the " ;D " gave it away!
heres a pic of the pullman with the black indelible line- works well.
helps me check qty AND how level i got it.
thinking of lathing a .5 mm x 1 mm slot and filling with red paint for even better visibility.

Im glad it works for you.* Id not recommend you to permanently modify your Pullman Tamper only because firstly I think Greg wouldnt like that* :o and secondly remember the level is specific to your machine.* Who knows wat machine youd have in 5 years time?* Work on the existing reference points and a feel of the tamp level. After awhile youll know if youve overdosed, underdosed or its about right. ;)
I agree with saoye. It doesnt make a great deal of sense to alter a precision tamper even if you can esp. when you change it from basket-specific to machine-specific. And presumably this is one reason you bought a Pullman which as I understand it, is a precise fit to basket width not depth but already has guides to help with depth (presumably as this varies).Originally Posted by 63717F6975100 link=1327631793/22#22 date=1328497166
Out of interest I just measured the tamped dose level in my double with a vernier calipre (not for accuracy or precision but simplicity). It came out to 14.67mm. I dont know if you plan a .5mm high or deep groove but even at .5 high you could easily finish with nearly 2% or .3gm error if using my basket. I reckon I get this range of precision when tamping by eye and feel by knowing my basket and tamper.
If youre using the rice or 5 cent test to determine accurate dose weight (they are both accuracy tests not precision tests), do you really need a permanent mark ?
Just my 5 cents worth. But then I can afford rice but not a precision tamper!
not sure why i need gregs approval to modify my tamper?
and Im quite happy to bet that ill still be using the izzo in 5 years time ( put up with the sunbeam that long).
The only proviso is i get shot up the b*m with a rainbow and i go out and buy a Kees Van Der Speedster ( but ill need a bigger bench and kitchen and house as well) so i guess a new Pullman would be in order.

Actually i already modified the pullman: took 0.5mm off the diameter because i felt it was a little to tight in the sunbeam. seems perfect in the izzo. a mate now with a minore has asked me to mod his tamper the same after we both upgraded from sunbeams.
i have access to a proper machine shop lathe so not suggesting others try unlees they are confident & have the right gear.

Thank you saoye! I have been playing around with tamping/dosing since I got my PST baskets and Pullman tamper. I havent had enough consistency - this is going to be a big help.
Hi Jesseka, I hope it helps you out! :)
Well, the rice test (cous cous) showed that I was under dosing, I was using 19gms but the rice test showed I needed 22gms, since then my shot times have reduced a couple seconds, though the coffee produced hasnt really jumped in flavour, in fact side by side, the shots only difference was the 22gm shot was darker to look at but taste was very difficult to discern. Maybe if it was a high end machine the difference would be more noticeable, but in the Silvia, it didnt make or break anything really. Will try again with the Costa Rican when its ready in a couple days, maybe the different beans will show a better result.
Hi Ausnadian, if youre forced now to updose more from 19gms to 22gms I would have expected your shot time to increase (ie flow slower) if no other change to grind etc. A darker pour does make sense though. Is that what you meant?Originally Posted by 4571776A65606D656A040 link=1327631793/28#28 date=1329166841
Yes, my mind was thinking one thing as my fingers typed another. I meant the extraction amount had reduced, not the time, I still stopped the shot at 26 seconds.Originally Posted by 4C5E50465A3F0 link=1327631793/29#29 date=1329176932
