I just use a round file, run quickly up and down the battery slots (Hara does too... see here
Hara Cyclone build guide). I have seen on here that someone used a Dremel sanding drum bit, and just rotated by hand. Was the same diameter as the cell, and seemed to work really well.
In terms of chassis edges, I use some 400 to start, then 600, and then 1000 (if I feel like it). All used wet, as thats the best way to avoid getting too much carbon dust everywhere.
