I am looking for pics, maybe a tutorial, on pressing a barrel with the trunnion already welded into the receiver. The only pics I can find are of pressing a barrel into a trunnion that has not been welded to the receiver yet.
Ya mean like this one that I made:+1
I would also like to know of any source for the receiver clamshell jig to use when pressing/removing the barrel pin.
Of course I would hate to ruin my $1300 target rifle chambered in American Eagle.
Ok, I don't know what make that rifle was... but I'll be dammed if they are that easy to remove! First one I ever removed, I bent the punch and broke 2 HHS endmills trying to cut out the center. I use an arbor press now... and even with that I about sh*t my pants cause I have to pull down on the bar so hard.Barrel removal
+1 here as well!!! That jig looks pretty slick.+1
I’d also be interested in purchasing one of these jigs too.
I always press them out from the inside out (push in the direction of the muzzle) and if there's no front sight, install from the same direction. If the front sight is already installed, then they can be installed from the front towards the back. It's just easier as far as fixturing goes to press from the inside out. At least, with the fixturing I've built it is.I am in the process of creating a SBR and want to remove my 16" barrel on my Coharie CA94 to be prepared for replacing it with an 8.5"barrel. Do I understand that the old barrel should be pressed into the receiver for removal? It appears that the front sight tower might be welded to the barrel which would make this impossible. Can/should I press the barrel out forward (from receiver toward muzzle) directionally speaking? Thoughts?
Bummer. I was thinking about getting it as I now own a bunch of parts kits. I've got a machine shop in my basement, and have a general idea on how the HK roller locking system all works, but was looking to learn some of the finer points of assembly but I guess the AGI dvd is not the way to learn it.Actually, the AGI video doesn't deal with pressing a barrel at all.
...but it's basically useless if you already have any kind of clue about how the rifle works. The AGI armorer's video also skips over the spring wrestling required for trigger pack D&A, probably because it would be too hard to avoid cursing on the video.
Depending on the fit between the parts, it may be required to heat one side and/or cool the other before attempting to press fit the parts. Or in cases of home mechanics that don't have high enough capacity presses it can make the fit a bit less tight so a lesser press can do the job.I over heard a friend at work talking a bearing on a Harley wheel and freezing before pressing....
