I have the same problem with a countertop mill. I ordered it online, complained to the seller and they paid some back but they were not admitting that this thing wasn't food safe. The amount of shavings that comes off is quite notable, it is more like dust then shavings in fact, and I'm sure it...
What fitting do you need to connect the pipe to the co2 cartridge charger? Also has anyone thought of adding a pressure meter? I am wondering how that would connect in line. I am thinking of building one of these, to be able to not only charge but also monitor the pressure in the mini keg.
