Getting closer on some projects, anyone had any recent experience with their heat treating services using the Burgess Method?

Yes, but have you had used any of their services lately?

I read of someone recently (can't find it now) getting back a warped and unusable receiver from them.

I think it was D'Arcy Echols??

Burgess's method was specifically developed to minimize warpage, however it cannot be totaly eliminated. 99% will not experience any warpage issues. Just like contouring barrels; the majority of good barrels will not walk with proper methods but occassionally you get one that has a mind of its own.

I know someone that just got back about a dozen receivers with nary a hitch.

That is what I wanted to hear.

So, do we have any idea why some receivers warp and some don't?

Pardon my ignorance, but what is the "Burgess Method " ?

I'm a relatively new member here, so hopefully I can actually add some value..while standing in awe of what I've read here, having read posts going back to 2001...

Looked this up- patent-
http://www.google.com/patents/US2124459
(read the whole thing if you have trouble getting to sleep)

Basically an approach to rotational heat treatment and quenching designed to minimize distortion while providing a more uniform case.

It was the process Tom Burgess developed/prescribed to/whatever with Pacific Metalurgy to recase mausers.

That patent has quite a number of mis-spellings ,typos and other confusing things like "sur-15face " .
Doug ,it's spelled Metallurgy !
In any case Ihaven't ever seen the Burgess method in operation . Heat treating the receivers is complicated by the ejection port cutouts.A 1200 F stress relieve is a good way to start heat treating to prevent warping. In production with all parts are the same size fixtures are helpful.

Heal thyself, physician.

I had a couple of Argentines recased by them last summer and everything came back just fine. No issues whatsoever.

Doug, oops missed that one . The only bad part of my education was a spelling class in seventh grade that was "Progressive Education" which messed up my spelling forever .

OK, so what is the deal with that wacky punctuation spacing you use? lol

And to think I started reading this thread to try to gain some information/knowledge about heat treatment of 98 actions. Hope it gets back to that.

One reason I am interested is to see if the "soft"
Spanish actions are brought up to standard by this procedure.

Are they?

Proper Mauser actions are made of a steel similar to a 1018 , a low carbon steeel that does not respond to HT. However those actions are carburized which adds carbon to the top layer of the steel. That's what makes them hard . If there is no carbon added it can never be heat treated and hardened !!
When I was in gunsmithing school [ CST early '70s ] I sent my M98 out for HT. That included adding carbon . I can't remember what company did it .That company's proceedure satisfied me as a metallurgist. It was my deer rifle for many years !!

Has anyone ever checked to see how deep the case is one one of the case hardened Mausers from PM?
