Or, like the old sherril sticker,
"If birds had chain saw feet.....
treeman, 85-110 feet.
I was in a 140 foot fir recently, just a baby. Only a 3 foot butt, it was forced to grow tall by the two topped ones right next to it. have done lots of 120 plus ones lately. There are few residential trees here over 150 feet, but give us 20 more years- if the loggers and developers dont get em all, there will be more pushing 200 feet.
More fun was today's pruning of a 80 foot wide by 60 foot tall bigleaf maple. Gotta go back for more after shots, as the battery died. It needed a lot of end weight pruning and some extra reduction on leggy, brittle branches that had some breakout, decay and poor compartmentalization. So, to some here, it might look a bit overpruned, but it isn't. It was open in the center already anyhow. We produced about four yards of chips, not much.
dont feel too bad about doing too much on your oak. It was not a mature tree, so it should be fine. Just take less of the center out next time. Dead, diseased, dying, crossing is all, plus fine pruning out near the ends if needed-1/4 to 1 inch cuts.
Here's a before shot, sorry about the overhead lines:
