I didn't have that problem. If you use a light touch and go slow, it can work. Once the cut starts it will continue in the same place. You can always try a test cut or two farther out from the final length.
I have a buddy who needs me around to say "righty-tighty, lefty-loosey" when he works on anything mechanical. I wouldn't tell him how to cut a barrel. I'd give him the name of a decent gunsmith instead.
Good idea testing it further down. I may give that a try.
Haha I'm not that guy. I can DIY most things. I just figured I'd I end up deciding get the barrel ported, I may as well just have the smith do it all.
