I had a rotor that didn't want to come off today. A nail hammer didn't help (even with my beloved Kroil). I pounded and pounded. Eventually I decided to go buy a torch and a four pound hammer. Luckily, that four pound hammer was no match. The sound of that rotor breaking free was so delicious. I didn't even open the torch.
There's a valuable life lesson here.
Sometimes you just need a bigger hammer.
That's all.
