That's the the other "standard" problem with the Hesse/Vulcan receivers, the ejector isn't hardened.
Here are the options I collected from my gunsnet post many weeks ago:
- Use a torch to harden the ejector wear area & delay the wear
- Grind down, weld, then dremel a new ejector wear area
- Use that liquid "kasenit" hardener from Brownell's to harden the wear area... this is a case (surface) hardening compound.
People have used all three methods, but the easiest for those like me w/o a welder handy is to use a torch to harden the ejector.
MAPP is probably best...
1. heat the ejector until it loses magnetism (should be orange-red)
2. plunge it into motor oil.
3. Put out oil fire.
4. Enjoy.
If you weld it, get someone with a TIG or MIG to weld an oversized bead onto the ejector and then dremel it down to the correct size/shape. The heat from this will anneal the steel (or normalize, never can remember which) - make it more brittle - so that in itself should be enough heat treatment. Again, others posted this method has worked for them.
