Pic's of Hardening of Oprod/M1

[eclancy]

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 2700 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

Is that first thing like a little op-rod toaster? They'd slip the piston-end into/around that little coil to get it hot, and then quench it to harden it? Cool.

Guys,
The most important file is in the area of the Guide Lug. They are saying it will FAIL at 2700 rounds unless treated. I guess that part of these files does not seem to be as important as I thought it should be.
Sorry

Looks like they said it failed at 2,700 rounds.
