This is my 1st time to chamber a rifle barrel, the barrel blank that I plan on using isn't long enough to fit into the spider on the outboard (correct me if I am saying the wrong thing) side. I watched a video where a guy had what looked like an action truing jig holding the barrel in the chuck and didn't use the spider either. Now keep in mind I don't have the money to go out and buy expensive equipment, so my question is there a way to be just as accurate by holding the barrel in just the chuck jaws? What if I had something holding the barrel concentric in the spindle? Please be easy on me for my lack of knowledge. Thank you for any advice!

Thread the muzzle end and make an extension, it sucks if you're doing it on a blank because you'll have to thread it again (assuming it will be threaded) after you then make an extension for the breech end.

Re: For the guys who have chambered rifle barrels?
I ran into this problem often. what I ended up doing is taking the extra face plate that came with the lathe and turning it down in diameter. then I drilled and tapped 4 holes 90* apart for set screws. grizzly sells these but I am not sure if they have them for your machine. I can now work on barrels less than 18" long.

I guess I'm not quite sure what exactly you mean?
I had also completely forgot about doing it between centers, or is that a bad idea? Thanks guys!

Re: For the guys who have chambered rifle barrels?
OK - this is an "unorthodox" method, but I've used it before in this scenario.
I have made bushings that hold the muzzle end of the barrel secure and "relatively" centered in the headstock when it's too short to extend out the spider.
The last barrel I used this method on is a 6.5x47 that's producing sub 2" groups at 500...so I guess it worked OK.

Re: For the guys who have chambered rifle barrels?
I threaded an extension onto the end of my barrel so it would reach the outboard. Think threading it for a muzzle break, but only doing it before you cull the 1.5-2". Then I threaded the interior of a piece of stock, and threaded it together to lengthen it overall. After I was done with the chamber, I simply parted off the threading and re-threaded for a brake.
Now I say it worked alright, because I was unable to time the bore runout on my barrel to the 12:00 position because I couldn't get an indicator into the bore with the extension on there. It worked for me, and I don't have enough runout to cause me any problems with my scope setup.

Re: For the guys who have chambered rifle barrels?
looks like this and shortens the distance through the headstock over 3" vs. the 4 jaw on my machine.

Re: For the guys who have chambered rifle barrels?
Ok thank you guys for the ideas, I am starting to picture in my head what needs to be done. Just glad it can be done without investing a TON of money into it!

What size lathe are you able to get an 18" in there? I made one of those also, but it only gave me maybe an extra 2" max over using the 4jaw. And I dont even like using mine because turning the bolts moves the barrel around and its impossible to dial in. (not a flaw in the basic design, probably just my design)

Re: For the guys who have chambered rifle barrels?
I have no issues whatsoever in dial a barrel in with the spider. its a pm12x36 lathe.

This is how Don Geraci chanbers his barrels , he uses a long needle indicator and runs it in roughly where the throat is gonna be and dials it in their.
He produces so amazingly accurate BR rifles this way so it cant be all that bad
