Just took my three Vulcan recevers with serial numbers of just under 50, just under 900 and just under 300, and gave them the "file test" on the ejectors. Looked liked all three cut with no problem.

Ejectors are obviously soft. "heated treated" what ever that means, maybe, "hardened" absolutely not.

These things are going to wear out before a couple of 100 rounds.

Are there any other fixes besides the "weld and grind method"?

Try "kasenit" from Brownell's, that is a case hardening compound.

Also, I recall someone posted they corrected the hardening when they heated the ejector up to cherry red w/ a torch, then quenched in motor oil. This WILL start a fire (duh) so be prepared.

I THINK the method would be heat to cherry red, then while still red to orange, quench in mineral oil, then heat to blue/purple (you know when it gets swirly?) then let air cool. I believe this is the proper method for flame hardening... I thought I saw some plans for a homemade reciever and in the plans it had the method for flame-hardening... trying to call on the memory bank here... but it WAS on this forum... I'll try to find the thread...

And... if you do try this, let us know if it is worth the effort... doesn't sound like a whole lot of work...
