I'm hoping to acquire one of these in the near future, probably used, from the auction site. As I haven't had one of these before I did some research on Blood & Gore. Patrick's closing statement is that, because of the way that these planes are constructed, ie the rear and front soles are not co-planar, there is no point in practicing sole-lapping. So, my question is: if the sole is marked/scratched/pitted etc, what is the best way to clean/lap the sole?
