I just received one today for my new Mark X project. Unlike other ones that I have used in the past on military bolts, this one goes on realy tight. I get it all the way on except for the last turn and it stops dead in its tracks. What can I try to get it to go the rest of the way without wrecking the damn thing. | ||

valve lapping compound, finest grade you can get... LIBERALLY (all gun nuts note, this does not mean "like a liberal" ) dab it on the threads... turn in to snug, turn out, repeat a zillion times jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Do as I did.....return it with a nasty letter. I used a dremel and stone to ID grind the bolt in the lathe and finally created enough clearance for it. It worked beautifully after a lot of fitting. The second one I tried didn't fit at all.....I returned it to Brownells....this is a common problem and Dakota just don't seem to want to fix it. Screw em!!!!! /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

Vapo I might agree with you if it didn't go on at all, but like I said, it goes almost all of the way on. Its just that one last turn that won't go, which I can't figure out. I mean, the threads would have to be decent for it to go on as far as it does, so maybe its the last thread on the bolt itself thats horseshit??? | |||

use some bluing to see if you can determine where the bind is.....In my case it wasn't in the threads....once you see where it's binding you can try to fix it. Damn things are truly frustrating...but when I get my camera here I'll post some pics.....they're the best thing ever to happen to a '98 mauser. /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

Well, I tried Jeffe's solution and by golly it worked. I used some Brownell's 800 Grit Garnet Lapping Compound that I got with their Scope Ring Lapping Bar, and just kept lapping and lapping. After three changes of the lapping compound it finally went on all of the way, and after a bit more lapping it is working very smoothly. So thanks to all for your encouragement and help. | |||

Tried some Dykem on mine, and it looks like the shank behind the threads on the safety is rubbing. It may also be that the threads aren't exactly square to the shank. But boy, is the finish on this safety pretty. flaco | |||

22, glad that worked out for you.. pull it out and look at the threads under a magnifing glass... bet the pitch changed just a hair. jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Chase the threads, inside and outside, with the proper sized tap and die. | |||

never seen buttress thread taps and dies before. and if you found them, I would have to think they would be a little on the high side. Look at it closely and be sure it is really the threads and not soemthing hitting some where | |||

The machine supply company I use (Rutland/Airgas) can have their supplier make taps or dies in any size you want. Brownell’s sells a chasing tap for Mauser bolt bodies to clean up threads after welding, so if they can have those made they can obviously have others made. Are they the “best†or “cheapest†answer for the problem, probably not, but they do exist. I had tons of people (some of them in the tool and die business) tell me you couldn’t make a thread chasing tap for the square threaded 1903 receivers. Well, I have four of them sitting on my bench that I had made up using the blue prints from Springfield Armory found in Brophy’s book, and they work great. | |||

what would you guys recommend for a little angle checking tool so as to check grind angles on these 3 position safety install jobs. | |||
|

Starret makes a nice little pocket sized set of angle gauges...same as a feeler-gauge set with the individual leafs that swing out. | |||

Rick Enco doesn't have them in Starret. Who else carries Starret stuff. | |||

22WRF, you might try www.crescentgage.com. I buy my Deltronic gage pins from them and other measuring tools. Ask for Bill Rupert, the owner, he is a real nice guy. Butch | |||
