I got a few rounds of red oak recently but did not know what the holes in them were. In the picture below they are the black circles, some of which come out through the bark at angles. Anyone have any information on this? I wanted to use a few of these as splitting blocks and I hope those holes are not indicative of any rot/disease. Also attached is a pic of our stove finished, in jail with the fence around it. I still have to repair the space in the hardwood floor where a wall had been, any suggestions on how to do that?
