If he can do it for about what I would have in the tools I will probably just let him do it. I have too many tools laying around now that I bought for one- time jobs. Thanks for the info though. If the smith quotes me something crazy I will look into it.
*Here's what you will need, and a couple items you just might need. Of course your gonna want a vise and blocks to hold onto the action with (note: some folks prefer to hold the barrel). You will probably need a hammer to give the barrel nut wrench a smack the first time the nut is removed. After the nut is unscrewed about a thread or so the entire barrel can be unscrewed out of the action by hand.
* Going back together, I like to give the barrel threads a very light coat of Neversieze with Nickel (do not use Loctite Antisieze!), and then screw the barrel into the action till it's about two threads shy of being where it needs to be. I then drop in the headspace gauge and screw the barrel into the contact with the headspace gauge. Now screw the nut into the action till it's solid. Now just tighten the nut till it has about 25 ft. lb. of torque on it. Pull the head space gauge out of the action and wipe off any of the Neversieze on it. Reinstall it and check out the feel on the bolt when closing. The barrel nut will normally pull the barrel forward about .0025" to .0035" taking out the clearence in the thread as well as stretching the thread ever so slightly. Making it be in ridgid contact with the female thread.
* tools you might need in a pinch (if the nut is very tight).
1. An internal action wrench
2. always keep three or four once fired cases in a plastic bag for further checks on the headspace
3. a 12 pack of Sam Adams October Fest beer
