Seen this little 11 degree crowning tool on another forum, and was wondering if anyone here has ever used one? If so, how did it work for you - good, bad, not worth the time or money???

Was thinking it might be handy for someone who doesn't own a lathe (like me), or even if you do have a lathe for that matter, to cut a uniform 11* crown. I assume you would still have to do some polishing to some extent (which is no big deal), only part that concerns me is the guide/centering rod on the front - would it not mess up your rifling a bit while it is turning?
