Wade Pruetz 103 Posted July 14, 2010 Author Report Share Posted July 14, 2010 Looks like a lot of fun! I haven't spent much time on a lathe since high school but I have always wanted a decent benchtop lathe for my shop. I am always looking on Craigslist and ebay but they seem to be overpriced or pieces of junk. Quote Link to post Share on other sites
loner42 6 Posted July 14, 2010 Report Share Posted July 14, 2010 Here's a few pics of the 6 Bulg. ( new ) barrels from Copes after I chopped and re- profiled them to Krink specs. I had to Knurl one of them as the Tula trunnion it was for was about .003 too big for the barrel . Uploaded with ImageShack.us Uploaded with ImageShack.us Next up are 2 E.German Virgin barrels and a Virgin Bulg. .223 barrel . Cheers................. 2 Quote Link to post Share on other sites
Wade Pruetz 103 Posted July 15, 2010 Author Report Share Posted July 15, 2010 Nice, so the Tula trunnions are a little bit bigger than the standard 74 trunnion. Good to know! Did this turn out to be a bigger project than you thought? It looks like a lot of work and it always seems that doing it the first time can be a huge learning curve.

loner42 6 Posted July 16, 2010 Report Share Posted July 16, 2010 No, they are all 22mm.. except the one which was .871 dia. It's just standard deviation in the tolerances. I built 5 M92 kits prior to this project and all had the same size trunnion and chamber dia. except one. It was .010 bigger than the rest and the trunnion was too, so the interference fit was still about .001, just .010 bigger than the rest. As far as was it a bigger project than expected, I'd have to say yeah. Alot of measuring and laying out dimensions , making drawings, double checking and soforth, but I'm pretty used to all that. I just don't have to do it every day now that I'm retired..................... Quote Link to post Share on other sites
Wade Pruetz 103 Posted July 20, 2010 Author Report Share Posted July 20, 2010 Well at least you get to work on things that interest you, I think I could spend many an hour in my shop if my real job didn't get in the way. Happy retirement! Quote Link to post Share on other sites
beefcakeb99 572 Posted July 20, 2010 Report Share Posted July 20, 2010 how are these coming along, I may be interested after some reports and reviews Quote Link to post Share on other sites
diescheize11 0 Posted July 20, 2010 Report Share Posted July 20, 2010 im also interested in this topic. i came across a topic in another forum about cutting these barrels down and it was between a pretty high end builder and another guy just asking questions. so the builder said the accuracy isnt really effected by the twist rate. im sure the ruskies changed the twist rate for a reason though, but i bought a copes barrel just in case the Rguns barrels turn out to be the usual shitty "US 5.45"s.

Wade Pruetz 103 Posted July 20, 2010 Author Report Share Posted July 20, 2010 Accuracy will be affected, period! Now if you only want to shoot close quarters it may not be a problem for you. My friends Bulgy is accurate out past 300yrds. Thats right a 5.45x39 8" barrel krink was hitting a 12" piece of steel all day long at 300yrds. I personally will not be happy unless mine has similar accuracy. Now if you can get a barrel that is a 1:7 twist rate that may be close enough to stabilize the bullet but a 1:8 ratio may be a bit slow for an 8" barrel. Quote Link to post Share on other sites
diescheize11 0 Posted July 21, 2010 Report Share Posted July 21, 2010 (edited) ya, im guessing your right niner..... but id still like to hear if these cut down barrels can still achieve OK accuracy even though on paper they claim it wont. actually i was curious as to where i found that info about my first post, so i dug it up and here it is if yall want to read it. http://www.warriortalk.com/showthread.php?t=68739 also im pretty interested in your services loner42. i hope youll be doing this for the next few months. im currently deployed to shitland for the next couple months so thats obviously in the way.

Wade Pruetz 103 Posted July 21, 2010 Author Report Share Posted July 21, 2010 Yeah Will at Red Jacket pretty much said it on the the other post you are referencing. It will go bang and inside his shop range it hits paper but he has no real accuracy comparisons. I find that a lot of these guys don't worry about the details like accuracy or authenticity, they seem to be more interested in can I do it or can I sell once I do.

RGuns barrels from Green Mountain have a lot of unanswered questions, like are they hammer forged, crome lined, and journals cut correctly for a krink. I am waiting like everyone else to see the accuracy results of these barrels. Quote Link to post Share on other sites

Yeah more than one person has wondered if Rguns is just floating this barrel story to sell krink kits. Loner's work looks great and being that the 5.45 is a light grain bullet the 1:8 barrel may be just fine for a krink application. I just hate to build a krink around a barrel thay I am unsure of. We should know something soon. Quote Link to post Share on other sites

On this one and one other I did the whole enchilada............. cut and profile barrel , cut new crown, drill new gas port , cut new HG ret. groove .........demill the entire kit and press out the stubs, reinstall and pin parts on new barrel, press barrel back into trunnion, headspace , drill and ream barrel pin hole, and then press the barrel back out. Finish with the extractor cut.................. Enjoy................

loner42 6 Posted August 6, 2010 Report Share Posted August 6, 2010 Well, someone finally has finished a build and did give a somewhat range report, not in great detail but he seemed to be content with the accuracy for the distance and type of shooting he was doing. Hope you can view this if you are'nt registered there. This particular build was done with one of the six Bulg. barrels pictured in the above post. It starts in post #26 http://www.akfiles.com/forums/showthread.php?t=68338 Quote Link to post Share on other sites
Wade Pruetz 103 Posted August 6, 2010 Author Report Share Posted August 6, 2010 Barrel should be there tomorrow. I am sure we will start getting some more detailed range reports once the tax stamps start returning. Quote Link to post Share on other sites
loner42 6 Posted August 11, 2010 Report Share Posted August 11, 2010 Here's some pics of the latest project barrel assembly just completed. It started out as a Bulg. .223 Krink barrel assembly, but the parts were canted on the barrel and the owner wanted them removed and reinstalled on a 16" Virgin Weiger .223 barrel, barrel pressed into the trunnion and headspaced , barrel pin hole drilled and reamed, and then removed. He also requested that the muzzle threads on the Weiger be removed somehow but without cutting the barrel. I decided to turn the threads off and reduce the dia. enough to press a sleeve of sufficient wall thickness on it and then turn the barrel back down to the proper size all the way back to the FSB/GB. Made the sleeve from a piece of cut off Bulg. barrel . Uploaded with ImageShack.us Uploaded with ImageShack.us After sleeve was pressed onto barrel.............and the orig.
