Please send your postal mailing address and I would be happy to send copies of these articles to you.
There are many books that discuss engraving techniques -- you found several of the best ones. I attached our bibliography for engraving glass and diamond point engraving for your information.
So far, in skimming materials, I haven't come up with a specific answer to your question.
