Pic's of Hardening of Oprod/M1

[Clancy]

Gentlemen,
These two photo's are VERY IMPORTANT for the operation of the Oprod on the M1 Garand Rifle. Again sorry about the photo's as they are almost not there on the old microfilm. The Hardening of the oprod at the piston is important as you can see in photo 1. However, in photo 2 the hardening of the Guide Lug is also VERY important. Under the photo is the following on the Guide Lug.
NOT Hardened on number 1 FAILED at 1200 rounds.
Hardened on number 2 photo sill ok AFTER 12,000 rounds.
That gives the hardened Guide Lug a 10 to 1 improvement.





Some data has been posted before others have not.
Warning, before you go to my sites lower your volume as the opening page contains a sound file which has a loading and firing of the M1 Garand.

Gentlemen you know what to do. Push just a little more TIA. Gentlemen your doing a GREAT JOB.

Thanks again
Clancy

Guys,
The most important file is in the area of the Guide Lug. They are saying it will FAIL at 1200 rounds unless treated. I guess that part of these files does not seem to be as important as I thought it should be.
Sorry

thanks4 the info, Clancy

q: is that induction heating for anealing after it's been quench hardened?

q2: on bent oprods often read about on forums, is that because of improper heat treatment rather than load selection?

thanks.

Gentlemen,
There is an ERROR in my post above. It shoud have read 2700rds. NOT 1200rds.
Sorry about that
Clancy
ps dw1784 not much data on the oprod hardening but I thought it imprtant to post the pic file. If I find other data I will post it.
