texas30cal Posted January 27, 2014 Report Share Posted January 27, 2014 When I polished mine in the lathe I did leave a cross hatch in it, I have not used a flexhone for a chamber but have been using them on engines and many other things for 20 yrs or so, they do work very well and it is easy to get a nice finish.

Ahhhh the dingle-berry hone....used one a couple of times when we didnt take a second motor to the race and of course then burnt a piston.....hones a chamber and puts a crosshatch in there okay enough to get by....ought to work okay in the chamber with the right one :) Wash Quote Link to comment Share on other sites More sharing options...
texas30cal Posted January 28, 2014 Report Share Posted January 28, 2014 They work well for deglazing in motors but when honing to size nothing beats a rigid hone in a machine, we also used them a lot in the machine shop both for small bore finishing and for deburring crossholes in parts, I don't have a rifle that needs it right now but I am really wanting to try it on one, the paper on a slotted dowel did very well also but extra care must be taken to do it evenly and not mess with the shoulder.

Powerman Posted March 21, 2014 Author Report Share Posted March 21, 2014 (edited) So soooo lame. I have been super busy and have not even had time to go to the range till today. Heck... even today I had work to do at the wife's store, but I told her f' that... I'm going to the range. She didn't argue at all... all I have been doing is working for her... but it needed to be done. Anyway.... SUCCESS!!!! 210 rounds and not one single hic-up. I didn't even really clean my stuff from last trip. But since the bolt was apart I had to clean the action up. Put it together, through in the Mobil 1, and ran it all day. 40 rounds of CBC I had left, and the rest was AE 308. My brass looks good, nothing tore up from the extractor... but not one failure to eject. Oh ya, and I changed gas rings too. So this was new rings and the new JP Rifles 308 extractor. The only odd thing was I was getting some odd flyers every now and then. Most my brass was landing in the usual place, if not further... but every so often, I would get one at 3:00... or even 2:30. And that was with the AE 308. The usual brass marks were on my deflector... but there were a few more on the outside slope of the standard DPMS deflector. I have not really seen marks there before... but every single one was spit out. Bolt locked back every time. Squirted a couple drops in the bolt at around 100 and kept going. I still want to clean up my chamber but have not had any time at all. I think I will order another gas tube just because I'm tired of cleaning the top of my barrel. I have considered a stronger recoil spring, but most don't have a problem with the Armalite ones... but that is a cheap part so I will order one soon. At least now I have confidence in my gear. Sort of odd it took all that, but hey, first time I have not had any problems. Edited March 21, 2014 by Powerman Quote Link to comment Share on other sites More sharing options...

Powerman Posted April 3, 2014 Author Report Share Posted April 3, 2014 So I decide to find a gunsmith here. Send a few e-mails. One guy said $175 for headspace/ream/polish/test fire. Another guy said a few bucks and see what he thinks... I go to him. bunch of old codgers sitting around drinking coffee and talking about shooting their M1s off the back of his 64 Willis... :)) Head space is good. He says my chamber isn't tight. Showed him plenty of brass... he said my gas tube is trash... which I knew. I asked if he had one... My block was sealed, it was all coming out the end of the tube. Said he has never seen a gas leak like that.... said tube was $13 so make it an even $20 bill. I asked if he wanted to clean up my chamber... but he said between my extractor and fixing a gas leak, he does not want to fix something that isn't broke. Run it and bring it back if I have any more problems. 15-20 minutes I was on my way. Nice guy. I think I'm going to buy a good buffer spring and call it good for now.

Powerman Posted April 5, 2014 Author Report Share Posted April 5, 2014 When I got into this I found out it isn't as simple as one thing. So I wanted to keep the thread together to keep all the great knowledge shared by you guys. I ordered a 800 grit flex hone to polish my chamber. I'm confident my chamber is right, and the hone is the best way to clean the surface. I'm not worried about redimensioning the chamber. I not getting crazy, just want the surface clean. I went ahead and ordered a Tactical Springs buffer spring. They had one specifically for AR-10 tubes as well as standard M4 carbine tubes. I got their "relibility" kit with extra power extractor springs just to see what they had. I'm covered by JP, I'm just curious what they have. Can't wait to get to the range and run it.

Powerman Posted April 10, 2014 Author Report Share Posted April 10, 2014 So I got my Tactical Springs "reliability kit" today. New buffer spring and extractor springs. I don't need anymore extractor springs, but thought I would check out what they had. Why not for $3? And I thought I would post it here instead of other places. So the spring on the left is the BMC spring. The ones in the middle are the Tactical Springs kit. You put the small spring inside the large one instead of using other type of elastomer posts. No O-rings either. You can see it isn't quite as thick as Jp's spring on the right... but stout none the less. Interesting dual spring set up. They sent along a tiny bottle of lube so now I will keep both with the rifle for emergencies. My chamber hone gets here Friday, and I got my barrel all cleaned up from the gas tube leaks. I'll get my chamber polished up, and then get to the range next week. Can't wait to see how it all runs. Quote Link to comment Share on other sites More sharing options...

Magwa Posted April 10, 2014 Report Share Posted April 10, 2014 Have to agree STOP put all the tools and parts away...... IT WORKS! Quote Link to comment Share on other sites More sharing options...
Powerman Posted April 10, 2014 Author Report Share Posted April 10, 2014 The polish was something I wanted to do anyway. I mean an extractor spring alone wasn't root cause. I replaced that with another that many people run with no problems. I don't think it needs reaming, but I'll make sure it's clean. The buffer spring I didn't think was a problem. It's cheap to run a good one so I did. That at least was from a good article on reliability, which I still would not count mine as at 200. No semi-auto I have ever had has not run reliably. So this one has some proving to do. I do think it good to go now though. Some cleaning up and fine tuning is all. Trust me, my idea of fun isn't working on stuff forever. This build has been out side my norm. I don't own any 1911s if that tells you any thing. :D Quote Link to comment Share on other sites More sharing options...
survivalshop Posted April 10, 2014 Report Share Posted April 10, 2014 Never had a blown out gas tube . Did the sealed end fail ? Quote Link to comment Share on other sites More sharing options...
Powerman Posted April 10, 2014 Author Report Share Posted April 10, 2014 (edited) Never had a blown out gas tube . Did the sealed end fail ? Well? The block end was leaking. The key end seemed to seal tight, and had a nice clean part. I just mean it fit in the key well. But the block end was blowing out from front and back. Lot's of carbon on my barrel because I got tired of cleaning. And when the block came off... it was sealed. No carbon between block and barrel. So I took the block off again just so I can clean up all the carbon on the tube end so I can tell if it is leaking now. The gunsmith never saw one like that either. But since the DPMS block leaked as well as the PRI one, I am going with gas tube. Cheap fix to put on another one. Hopefully no leaks now.

Powerman Posted April 10, 2014 Author Report Share Posted April 10, 2014 (edited) Its nice to have an inexpensive part fail , as long as it not when your life depends on it . No doubt. At this point, I can't pinpoint what exactly was the problem. Bit of gas leak. Bit of fouling in the chamber. Extractor spring not strong enough to overcome those. What ever. This thread and this problem has taught me a lot about my rifle. That is always good. I'll get it all polished and cleaned up, and forget all about this.... hopefully. :D Edited April 10, 2014 by Powerman Quote Link to comment Share on other sites More sharing options...
Tripledeuce Posted April 11, 2014 Report Share Posted April 11, 2014 I don't understand the referance to 1911's. I'v seen hundreds that shot well out of the box, and did so for years, As a custom smith, most of the work I did on 1911's were t make the gun more accurate, or taylor it to the customers demands.

Respectfully Terry Don't take it personal... seems like those that like to tinker love 1911s. Most the people I know buy them as projects... that has nothing to do with their reliability. I like doing my own work... but I'm not into tinkering for sport. Quote Link to comment Share on other sites More sharing options...
Powerman Posted April 25, 2014 Author Report Share Posted April 25, 2014 (edited) OK, officially calling it. Reliable. 200 more rounds today not a single hiccup. Didn't even use any lube during the shoot. Normally I would throw some on the rings and carrier in the middle. There is a still some gas leaking at the block. It is from the tube/block, not block/barrel. Not nearly as much as before. I cleaned it off after 100 and still some after 200. Perhaps it will seal, maybe not. Front and back like before. I can't say good or bad on the Tactical Springs buffer spring. Seems like before. Not a lot of noise. But with all the work, it did feel "solid". I can't tell a big difference between it and the AR-10 spring, but I should get some longevity out of this one. All my brass was 3:30, completely consistent through out. I was shooting American Eagle 7.62. My brass is not marked anywhere at all. I cleaned up the chamber with the 800 grit flex hone. It had a mirror finish before. "Rougher" now, but 800 grit is still "polished". I can't see anything on my fired brass that wasn't there before. May or may not have been needed, but I know it is clean now, and so is my brass. I'm sure I stretched this out longer than needed by not being systematic about it.... but YOU GUYS ROCK!!! You sure did help me a lot, and I learned a lot along the way. I can't thank you guys enough. Bring on the Zombie Apocalypse!!! Edited April 25, 2014 by Powerman Quote Link to comment Share on other sites More sharing options...
