Either way you want to wrap the frame to protect the paint though, regardless of method.
I doubt it would take a half an hour. Looking at my own New York lock, I'd be willing to bet that it would take less than 60 seconds.
Also I can tell you that
it'll get too hot to touch either way, but a cutoff wheel puts MUCH less heat into the part than a torch will. If you cut up thin sheet metal for instance, a welding torch will blaze right through it, but also the torch heat will warp the sheet badly. A cutoff wheel will slice right through the sheet metal but not warp it up from heat
at all.
