This piece was turned once, looked nice, but I ruined it by drilling a depth hole straight through the bottom. So it sat out for a day and warped a little, so then I microwaved it to dry it out quicker to just use it as a learning piece, warped more. So when I was rounding the outside again, instead of a smooth finish, it looks as if the wood is being torn out instead of cut. I believe it is from 1 and only 1 reason. So what is your educated opinion on why it is doing this. Take a look at the pic attached. Thanks for the help.
