I sent you a PM, but yes, MOST small thread Mauser rifles are the same, with a few exceptions.

 

How did the 'smith attempt to remove the barrel?

 

I have removed many a barrel from LR and SR Mauser rifles. I have never twisted a receiver. I wonder if he used an action wrench. Then I heat mine a bit several times over a few days and spray Kroil at receiver and barrel connection. I have had some that felt like welded together. It sometimes needs to be heated finally and then taken off with barrel vise and action wrench. Barrels are same size threads on SR. Of course you need to do head spacing

 

Found these pics on the net a while back.

 

You don't need a complete new action, just a '91 Argie receiver. Should not be too difficult, I probably have one in my parts pile.
Will check tomorrow.

 

jp, I sure would appreciate any help you can give. This gun is my Son's and have been waiting to finish it for him. Gunsmith
has been under the weather for last four weeks with Corroded 19 so can't be much help. Great guy,,,great gunsmith...been at it for many years and this is the first time he couldn't complete a job.
God Bless and shoot safe.

SFB67, I think I sent you a message w/ pics, it's my first attempt on this new fangled board system. If it does not come thru, lemme know.

 

jp Nothing as yet. You could try sending them to my e-mail,ie., Gripmaker@suddenink.net

There is no excuse for damaging a 91 action......the tennon buts externally against the reciever ring,and the moment any difficulty is encountered ,the smith should have gone for a relief cut.

 

some additional comments:

• the Barrel shank drawings posted above in post #5 are from the book 'Bolt action rifles', 4th edition. I've posted these pics originally here in the forum.
• the difference in barrel thread is quite small between Argy M91 and the M93's: 0.985'' compared to 0.980''. The thread shape should be the same. Thread length is significantly longer with the M91 barrel (0.715'' vs. 0.645'')

--> others have tried to mount an Argy M91 barrel into a M93 receiver, since the threads are very similar. This still requires to shorten the barrel thread, and significantly work on lug space --> most M93's are for 7x57, while the M91 is for 7.63x53

From my opinion: it might be possible to mate an Argy M91 barrel to a M93 receiver, but the effort and risk is not worth it! Argy M91 receivers are available; try to use one.

hope this is helpful, Chris

 

Thanks Chris. I couldn't remember where I had saved them from.

 

jp re-send your email as I just noticed that I left a letter out of my email address. It should read Gripmaker@suddenlink.net.
I somehow left the "l" out of "suddenlink". Sorry, old minds sometimes forget.

 

Negative contact at this time.
SFB67, you can try contacting me, unless you are buried in the snow...

All better now

I've got a couple of NOS Swede M38 bbls that measure .995 greater thread diameter and would need fitting to go in a book standard .980 receiver. So not all bbls and receivers will be initially compatible. I sold another SR Mauser bbl to a fellow and he had to chase the threads to fit it to a M38 Turk SR thread receiver. 1891 receivers should be fairly plentiful. Even if you had to buy a $150 chopped specimen you could sell the parts to recoup the expense.

 

Yes thread Chasing with a flat, 12 TPI 55° Withworth tool with lathe on back gear ( slowest speed, and using a hand rest, ( not a toolpost fixing + 12 tpi Gearbox setting), and gently scrape ("chase") down an oversize thread to the measured receiver thread...
Standard measurements as published don't allow for tolerances in Manufacture. ( even if the same factory)
Size differences of even .0001" o(one-ten-thousandth)
Can cause seizure and galling of the threads....ripping out receiver threads when screwing off a barrel!!! I have acouple of Brazzy
Receivers with mashed threads...

Mauser and DWM didn't start using Johanssen Blocks until 1898 or so....Johanssen ( Swede) went to Mauser to supervise the M94 and M96 rifle manufacture for Sweden, and invented his " Jo blocks" on the train ride home to Sweden...he found Mauser's tolerances too sloppy in the pre-1898 built rifles...by early 1900s , almost every gunmaker of any importance had adopted his blocks, and even Henry Ford wanted to buy out the patent...Jo. allowed Ford to make his own blocks.

Have a VZ-24 action and a WWI Saur & Sons with the 1920 permission stamp. One Czech Persian mauser carbine barrel,and a 1909 Argentine barrel,one Kongsberg 306 barrel and a couple others. The first two barrels will not screw in by hand. So in this case a gunsmith will have to pick up the threads in a lathe. The Kongsberg barrel and two others will screw in almost all the way by hand. So in some cases you may get lucky with a barrel which will allow it to be (and I hate to use this word) drop in fit. IF you get lucky and the barrel will sit upon the breeching ring in the receiver and front of the receiver. If not then the fun starts. And yes most if not all mauser barrels are threaded 12 tpi 55 degree Whitworth thread (98 barrels of course). I can grind most lathe cutting tool bits but much prefer buying them pre ground. At the rate I'm going they will last longer than me. And yes gaulling can and will occur on trying to fit oversized threads on barrels to receivers. Anti or never sieze or moly assembly paste on properly threaded barrels will make your installation. I've been present when a buddy who has a home machine shop to die for twisted a mauser receiver because he wanted to save the barrel. No Kroil or heat. I actually told him do a cut where the barrel butts up against the front face of the receiver. Did cost him a bunch of money because he had to buy a whole rifle just to get the new receiver. Most of my bubba;s are old mil surps with less than sterling bores. I take the sights off, stick the barrel in the lathe and machine away the ring that butts up against the front of the receiver. Spray some kroil on the receiver and barrel next morning and it usually comes off with a 10" pipe wrench.I have a steel block drilled and tapped 1/4"x20 tpi. Allen screws and some modified washers serve to hole the receive in place. Set the whole thing in a vise, lock it down and unscrew the old barrel. Sorry about the long post. Frank
