Congrats! If you can get a clean edge on the threads, maybe not even
any work for the files.

I was remembering the fellow (can't remember who, maybe he'll pipe
up) in Alaska a few years back, had an exhaust problem out in the
bush somewhere and found that the PO had simply welded the exhaust to
the studs etc.  He was not a happy man.
