I think that m10 and m12 refers to the size of the bolt that screws into them ... but Im not sure.Originally Posted by Coffee Kid link=1162116089/0#0 date=1162116089
15 is certainly the 15 degree handle.
There are a number of generic parts out there and it looks, from the webpage diagrams, that coffeeparts doesnt have the proprietary rubber handle. This handle is shaped ergonomically and is made of a nice, hard rubber with "La Marzocco" embossed into it. The rubber handle that they have is their generic rubber one (700616 and the m12 version), its still nice, but its not the genuine article and not moulded the same. The generic plastic handles that you referred to look much more like the synesso handles than the LM ones. If you want to see the actual LM portafilters, I borrowed someone elses photo in my latest blog post.
The spouts showed on the coffeeparts webpage also dont look like the ones that LM were using. They were using 511672/R for a while, but they showed me the new spouts that they are using at the factory last year. The adjustable spout had two major problems; (a) with time, and heavy commercial use, the adjustment mechanism wore out and (b) it spread the pour our so far that not all demitasses could capture both streams. Accordingly, they moved to a single-piece, open spout that can deliver both streams right to the bottom of the LM ACF demitasse without getting espresso on the sides and still separates the streams wide enough to be able to put two cups under it. From memory, that spout also has a squared-off base bit so that you can rest it easily on the edge of the counter for level tamping. Its a very subtle and clever design. I have seen a lot of La Marzoccos that are using 511672, which is a standard covered spout that spreads the streams out a little wider and, has a rounded base that cant be used as a support for tamping. This standard part is on our Azkoyen and our Synesso. Corey Diamond, of Epic Espresso, prefers it to the new LM spout, but I dont. You can remove the cover on this part to have an open spout if you want.
Surf around the coffeeparts webpage and Im sure youll see a lot of those parts come up on other manufacturers pages!
The actual cup of the portafilter looks right in the diagram ... important, cause thats one of the main reasons why youd buy it!
Anyhoo, if you want to buy one of these pfs, it would be worthwhile calling up Pedro to make sure that youre getting the real deal, which is nicer than the Synesso pf that you would otherwise be buying. Pedro might well direct you to the LM importer or their sub-distributor.
These differences are minutii, but I presume that anyone who would spend $100+ on a portafilter is interested in minutii!
If I remember, next time Im around our FB-80 with a camera Ill snap some photos.
