just a note: different species of oak have vastly different amounts of oil in them. other members of the red family (southern red, black, pin, willow, etc) have even more than northern reds, enough to be pressed out mechanically (or separated via other means). acorns from the white family (white, chestnut) have negligible amounts. the basically oil-free species can be ground totally safely with a (tougher grade) standard grain mill.
i do have a long list of favorite uses. will have to marshall my thoughts about them.
