I recently acquired (thanks, Paul the Roaster!) a mark 2 Conti Comocafe (the second model with the elevated lever, rather than the first model with the lever attached to the base). Paul had done a beautiful job rebuilding it, and I have been playing around with temp and dosing and tamp, and although not quite there, I have gotten some decent shots, especially from SO lighter, 3rd wave roasts.
Paul got it without a grate or portafilter, and he knocked together a workable portafilter from (as he puts it) a steam toy. I spent a morning with my neighbour, Bob the master plumber, in his metal workshop and made a workable (if inelegant) grate, and finished cutting off the bottom of the steam-toy portafilter (it truly is a frankenfilter!). Alas, it is so deep that you really cannot see the flow -- I may have to try to work out something with a small mirror.
REQUEST: If anyone has a proper Conti Comocafe portafilter, who could photograph and measure it (especially the outside diameter, width and length of the teeth, distance from top of tooth to lip of portafilter), I would greatly appreciate it. I am trying to see if I can knock one together. It is larger in (outside and inside) diameter than a pavoni or an olympia portafilter -- it appears to be about the size of Presso portafilter, but it has three 'teeth' rather than two.
(If anyone has a proper Conti Comocafe portafilter lying around feeling unused and unloved, get in touch with me! I promise to give it a good home.)
Also: A big thanks to H-Ber Zeb for sending me a e-copy of the Comocafe instruction manual! If anyone wants a copy of it - it is in the original French, I can provide an English translation as well - let me know. Merci mille fois!
