It worked, check the site for tricks and tips. Start at a 45ยฐ angle and then slowly go straight. My beat didn't get hot. It took a long time, but I managed it. I also have a thermal imaging camera so I used it to see if the bat was hot. It wasn't quite like that. I didn't apply any pressure. Eventually I did and my camera showed me how much heat He was producing, so I relented by applying pressure. Go slow and important, make sure you don't drill anything or get in the way of something under the sink.
