Barrel removal

Vlim · 05-18-2004, 09:46 AM

Hi all,

Remember my 7.65 Mauser parabellum with the little reloading mishap that I bought a while ago?

Well. I've located a correct replacement barrel, from leftover postwar Mauser stock, same 15cm 7.65mm barrel. So part of the problem is fixed now

Regrettably the owner of the barrel has no provisions for barrel installation and neither do I. So in order to check what possibilities I have, I'm very interested in barrel swapping stories, equipment needed, experience, etc...

Gerben, in order to change a Luger barrel, you must have the correct tools or the receiver or barrel will be damaged in the process. It is not a job for an amateur unless you can afford to mar the finish of the gun you are trying to restore. The fabrication of the correct tools would be expensive unless you have your own machine shop. My suggestion would be to send the upper receiver/toggle and the new barrel to either Herb Werle in Germany or Hakan Spuhr in Sweden to have the barrel installed properly.

If you insist on attempting this yourself do searches on "barrel removal" or "wrench" to find photos of the tools...

If you can't find any, let me know and I will try to dig them up for you.

Hi John,

Thanks. The 'wrench' search helped a lot. I also located your collection of wrench-images.

I'm just investigating possibilities and I'm never afraid of a decent challenge, so we'll see. The barrel is still in Germany, so transfer of barrel and old barrel/receiver to a German gunsmith like Herb Werle would be an idea.

Since this is a relatively 'fresh' 1970s gun, I hope it will be a bit more forgiving than a 70+ year old gun.

Rick,

Thanks for the info! I never bet on one horse so I'm trying to find out the possibilities and impossibilities.

Decent clamping of a very, very smooth barrel is difficult and I'm starting to understand why the postwar East-German barrels have a rough surface on the muzzle-end. I did notice some barrel-changers using lead as a means for extra grip and protection.

As I mentioned. I was lucky to find a barrel from the same production line as my original one, so that'll help (a little). And I wouldn't even think about barrel installation, were it not that I have been working on slightly larger German stuff for several years (Mercedes-Benz kinda stuff

. Also the barrel that needs to be removed is no longer usable, so it can be 'sacrificed' in the process.

Gerben, If you decide to do this on your own, considering that the barrel to be removed can be "sacrificed" since it is unusable, you can put the barrel in a lathe and very carefully relieve the shoulder of the barrel that touches the receiver...being careful not to remove any metal from the receiver. This will relieve much of the stress holding in the barrel.

You can also use acraglas in the vise blocks and glue the disposable wooden blocks directly to the barrel being removed instead of using release agent. This will prevent barrel slippage during the removal process.

Design your receiver wrench carefully to prevent denting or scratching the receiver...

Good Luck my friend and let us know what you decide and how it turns out.

Rick,

The bulge is very close to the chamber, so it'll be a really short baby barrel <img border="0" title="" alt="[Wink]" src="wink.gif" />

Hi all,

Some news on the barrel replacement scheme.

Rebarreling will be done in Germany by a local gunsmith, he will also take care of correct sizing, blueing (if the barrel is factory new and unblued) and having it proofed again.
