I don't think reshaping the tang area will solve the problem because of the borders and the fact that there are 10 lines on the left side and 12 on the right.
I am reluctant to post a name here because the fellow posts here occasionally and is a ACGG member. Perhaps there is a viable explanation regarding the checkering outcome.
He did mention computer problems in my last email exchange with him prior to me sending this last message.
" Despite the mis-alignment of the pattern that came out on my trapdoor behind the tang, I can recognize nice quality checkering. Not sure what may have happened there but it is my personal rifle and I can live with it.....i'm just glad that it was not on a customer's gun. There!!!! I said what was on my mind."
In retrospect, I should have said 'I will have to live with it' instead of 'I can live with it'.
For now, I have decided to copy and past the URL of this thread
in an email to the fellow and see if he has any comments either in a reply email or in a posting.
