Well, the fact that I said "talk to an engineering firm" seems to have been lost.
Hardened steel CAN be aneeled (sp?)
It CAN be repaired and RE-HARDENED.
An engineering firm can tell you wether the risk is there, or if it is really possible at all.
The cost of all the processes my make the attempt futile before you even start.
BUT, it might not.
Just ask someone who knows way more than we do about grain structure and rockwell numbers etc...
If we can safley repair overhead guards, to factory specs, for a fraction of the price for a new one (including all the engineering and inspections and re-certification), then maybe, just maybe, something can happen here.
The phone-call to the engineering firm will likely be free. It doesn't hurt to ask does it?
