Side channeling solved by accident.

Warning! Off-topic Geek Talk follows. I've been doing this off and on for awhile. In other words, when I remember, I do it. Now to the geek talk: I haven't heard any reference to nutation since I got out of the Air Force in 1982. The APQ-120 Radar System in the F4-E used a nutating feedhorn to

    How To Make Your Own Naked Portafilter

    Nice smooth finish. I used the same technique with an aluminum (yeah, I know) portafilter. If only I could use a grinding wheel on aluminum.

    Real Espresso from a Hamilton-Beach Thermoblock machine
