I am just getting into turning and have a couple dried blanks that I've started working on. The maple and cherry woods turned out very nice, smooth right from the bowl gouge. However, a couple oak (red I believe) bowls that I've tried have a much rougher grain and some grain tends to "rip out" during the finishing leaving small pits ... not near as nice and smooth of finish as the other woods I've tried.
Is this normal with turning oak? Is there anything I can do to avoid / help improve things?
