Now wait a minute, that may not be exactly as it sounds! What I mean to say is I finally have finished putting in (or laying) the plank flooring in one of the bedrooms, and yes the wood was hard indeed - solid oak. There are still some other things to do, like the 1/4 round molding, as trim all around the floor to molding edges, but that is nothing compared to all the splinters I have gotten already, and heck that will probably be clear pine. Much less likely to splinter, and easier with which to work.
Now back to Home Depot with two excess boxes of oak flooring (@ $59.80 each plus tax, you can bet I want a refund). I probably needed only one extra box to make sure there was a good measure in case of screwups, but I got 2 being the worry wart I am. Half of the wood in one of the boxes being returned is going back because it was warped so badly in one direction or another it could not be used, some other pieces were cracked (right out of the box), and others cut wrong at the mill. It pays to buy at least 10% extra when working with wood to cope with things just like that.
All the best,
