That's the ridged LaMarzocco basket,right?

Yes indeed the ridged LM basket.

How many grams of coffee are in there?

Not exactly sure. Somewhere between 16 and 18. My scale is +/- 1 gram, and I wanted to get 17 grams in there. I would suspect that it is closer to 17 grams.
I've come up with a way to measure the weight of the ground espresso with the Solis Maestro. I just weigh the empty bin, then grind enough in the bin, until I get 17 grams, weighing the bin when I think that I'm close. To keep the scale from shutting off while I'm grinding, I put my tamper on the scale. Based on previous methods of loading and packing, I believe that this new method is better. I was underpacking before.
SCALES:
Time for a new scale? I don't think that a 0.1 grams resolution is needed? So, question for the folks reading this.... is a 1 gram scale the best to get for roasting and measuring espresso? Or do you need to go to 0.1 gram????

On my picture there's 17 grams,locked & loaded it, left the screw impression with the screw slot,16 grams left a slight dimple,without the screw slot.

My 'loads' always leave the screw impression. I've never looked to see if the screw slot was duplicated.

That's pretty darn near perfect for an excellent shot! Cheers Ed!!

Thanks Craig. Shot was in the good catagory. Beans were on the 'old' side for us geeks. Currently surfing at 40 seconds.

P.S. Ed,on the surface of you packed & loaded basket,I see a highlighted reflection of a heart!

That's not a reflection, it's my new tamper....
(just kidding)
best regards,

Hi George,I never use ths single basket on Silvia either. I use the stock Rancilio double basket,& the LaMarzocco ridged double as well. The stock basket holds 14 grams & the LaMarzocco holds 16 grams,or 15% more coffee & gives a denser,richer shot with more crema. On alt.coffee the wisdom there is saying that the ridgeless basket is slightly better  thanthe ridged La Marzocco,& you can squeeze in a little more coffee,I think 17 grams. At 1st-line the ridged LaMarzocco is $5.95 & the ridgeless (with an encluded stiffer spring clip),is $11.95! I'm thinking of ordering it. This basket will allow a 58mm tamper to go to a deeper depth than hanging up on the ridge on the ridged basket.On a Reg Barber tamper,if someone asked Reg,I'm sure he would machine the piston a hair smaller,like 57.5mm. The only thing bigger is a TRIPLE basket that holds 21 grams!!,& I think it won't fit,unless you do some Dremel work on the inside of the poftafilter. It's true,a picture is worth a thousand words! Cheers!

I'm waiting for my commercial portafilter and I also would like to order some LM double ridgless.  I do have a LM double with ridges but on the stock Silvia portafilter it kept falling in the knockbox (I hate that) so my question is, with the commercial PF do I have to install the stiffer clip ?

CafeBeaud,I just picked up my ridgeless basket & stiffer spring clip from 1st-line(Wed,July 17/02 @ 10.30am). The commercial portafilter has a stiffer than stock spring clip installed, & holds the basket tight! I just mic'ed them, & specs are as follows:
  • Stock Rancilio pf handle spring                     .0315" (31.5 thou)
  • Commercial Rancilio pf handle spring              .040"  (40 thou)
  • H.D.spring with ridgeless basket                   .0515" (51.5 thou)
  • LaMarzocco style 15 angled pf handle spring .0495" (49.5 thou)

    More specs! Might as well keep it all in one spot...{:-D
    25.4mm = 1"  1/25.4 (1mm) = .03937008" =.0394" = 39.4 thou.
    58mm = 2.2852" = 2.29" for tamper dia.
  • Stock Rancilio double basket total height         .860  (860 thou)
  • LaMarzocco double basket total height         1.005 (1,005 thou)      
  • Ridgeless double basket total height                  .975 (975 thou)
  • LaMarzocco style Swift triple basket total height 1.169 (1,169 thou)

In addition, there is a slight variance in basket internal diameters (for your tampers) on all three! {:-/

  • Stock Rancilio double basket internal dia.   2.310" =  58.63mm
  • LaMarzocco double basket internal dia.       2.267" =  57.5mm
  • Ridgeless double basket internal dia.        2.315" =    58.9mm
  • LaMarzocco style Swift triple basket internal dia  2.310" = 58.63mm

  • Stock Rancilio double basket outside bottom dia                2.045"
  • LaMarzocco double basket outside bottom dia.                  2.180"
  • Ridgeless double basket outside bottom dia.                     2.000"
  • LaMarzocco style Swift triple basket outside bottom dia.    2.200"
     
    All measured .300 (thou) into the top of the basket, from the outer sealing rim of the baskets (for tamper diameter) where the spring clip groove is, for reference.

You know, the ridgeless is now working so well for me that I haven't even looked.  I'm getting great shots!

Actually, it depends.  You need to have the same diameter portafilter. If they are different diameter you are out of luck.  Also the depth of the portafilter and the depth of the basket can be a problem : some of the portafilter handles are not deep enough to hold triple baskets etc.

Do you guys get a screw impression when locking and loading, and then releasing the pf ? (not brewing).

I'm not sure if I am overdosing, and if so if it has any consequence. I really have to do a session sometime to experiment more.

What I do now is to overfill, swipe with crooked finger and then tamp. I can see a screw impression in the tamped puck before brewing so the coffee won't have much space to expand in.

When I see your pictures it seems like you're overdosing slightly too? but if the shots are good maybe this is all academic.
