The people who do this successfully don’t publicise the deals of the drying process. However it removes some four gallons of water per cubic foot and shrinks by up to a third of volume. Given it must be quarter sawn to start with, the attrition rate would be high unless you knew what you were doing.
Even the finished product that I have will require removal of about ten percent of the thickness to achieve flatness.
It is more dense than Oak, up there with tropical hardwoods like purple heart and with a beauty that exceeds blackwood and ebony, IMHO.
