I've cleaned up the messes from literally dozens of the " just dremel it" guys. Burred up pivot ends that won't allow the wheel to be removed from the jewel, cracked jewels, gouges in the pillar plate, pivots broken completely off, and of course the ever present metal dust in the movement. Not to mention that it's exceptionally difficult to get the pivot short enough without taking the wheel out of the watch. Hence the cracked jewels and gouges in the plates. And how in the world can using the lathe to do it be "too much"? I have done dozens of them that way with no problems of any kind. I've also done a few where I clipped the seconds post off with a pair of fine cutters and then finished and polished the new pivot end in the lathe. If you want it to run true then it needs to be both cylindrical and polished properly. Anything short of that is just a botched job.
