Ed and Turnbull are both mechanics heating up old shotgun actions. No reasonable gunsmith would give the guarantee I copied off of your post six or seven posts back.
sounds like you have never re hardened a shotgun receiver. well, neither have i. so, neither one of us really knows what we are talking about here, right?
And since you already admitted you don't know anything about case hardening how do you have enough knowledge to advise others to demand the guarantee from Doug Turnbull? You don't know anything about it.
If you call any gunsmith up in the country and tell him you are going to require that guarantee in writing he will hang up on you, including Ed Landers.
You can defend Ed Landers' process and skills without attacking bone charcoal case hardening. I am not attacking Ed's process or skills, I am just saying there is nothing wrong with bone charcoal case hardening done by a comptetent gunsmith. And the fact that the smith doing hardening will not give the ridiculous guaranatee you are advising us to demand is not an indication of a problem. You and Mr. Landers won't give that guarantee either.
Best,
Mike
