First barrel fitting

[liseo]

Hi guys

I decided to try install my first barrel,(Krieger 30 BR) but I have a lot of doubts. I fixed the chamber end in the tailstock and the crown end in the 4 jaws chuck. I dialed with range rods, after almost 3 hours I got almost done the centering work., who show .0005" runout. After removing the range rod, and spinning the barrel,seems that the barrel hole have a lot of runout, so I decided to put the range rod again and check. Dialing next to the muzzle, the barrel show a lot of runout (0.015"). But if a measure in the tip of the range rod, the runout is very low. So, where is the right place to adjust the barrel? Dialing next the muzzle or in the range rod tip?

A lot to learn, but i love these things...

Excuse my bad english, outside USA guy...

You need to get yourself a copy of Gordy Gritters DVD on how he chambers rifle bbls. It will answer many questions for you as well as show you his techniques.

This forum would take way too much time to communicate the successful techniques that you need to utilize and why.

There are several other books that have been published by excellent machinist/gunsmiths on the different methods to us to accomplish your task. Do a search and see what you need.

Gordy Gritters' chambering video is very good and can be had for a decent price from several places. If you go on YouTube, Bob Pastor (TheViper) has some great videos up that might answer some questions for you as well.

It sounds to me like you are chambering between centers and that either your basic setup or your indicating method is off. There are a lot of guys with more experience than me that might tell you I'm way off base though, so my opinion is probably worth what you paid for it.

I'm wondering how you got the rods in with one end in the 4 jaw and the other end in the tail stock.
Any reason your not using the 4 jaw and a spider, and working through the headstock ??

Beside the bad english, I believe that I need to know the lathe parts...
