Not much bucking to stove length. Lots of limbing and cutting to longer lengths though, but thats when the weight of the log is sufficient to not roll over on you. If I have to buck to stove length with an axe I'd probably try to rig something up. perhaps a log squared on 2 sides so as to lay flat and provide a flat side to prop the log against. I am not really sure, testing out a lot of different ideas would no doubt be the best way to determine a good method.
