My 7900 did fine freehand milling some 24" sugar maple with a 28" bar...I suspect it would have done even better with a mill attachment and something smooth to guide along.
I used mine last week that way on a 40" walnut, I had a 32" bar burried in it for about 10', the only time I stopped was to refuel, I don't want to do that to much I was getting a little nervous for running it that hard for that long, but it still blows 180 psi.
