>Ed,
What Russell says is right on. Big mess. At least with water stones the water catches the gunk and you dump it somewhere.
I like this system (I've had it for a few weeks now), but the mess is one drag (and I worry about breathing that stuff -- It's gotta be really bad for you).
It's other weakness is the speed at which the 80 grit disks remove metal. Critical to this system is the idea that the bevel angle needs to be set accuratly so you can just sharpen over and over with a quick hit and then microbevel. It really does work quick at that point. But it takes a long time to bring a bevel at some non-5 degree increment onto one. Burns through sandpaper fast at this stage in my experience.
The other complaint I have is the difficulty in getting the finest grit abrasive on the platter without bubbles. The platters are dead flat. The mylar is flat. But if there are bubbles it isn't flat anymore. I still haven't found a good way yet so I'm popping them with a needle. Painful.
And you can't flatten backs.
The system is good, but there definetly are limits to it.
