Another alternative is Professional Jeweler. There are some good
bench articles there on line with super illustrations. I don’t
recall one specifically on flush setting. Unfortunately, I do
believe you must register to enter the archives.
The Bench Magazine came to my place of work, apparently from a
mailing list. The article on flush setting was one approach to the
job. My technique is different. I suspect with the many bench workers
in Orchid membership, you might find some other approaches. If you
like, sometime after the Christmas season with a “reminder to me”, I
will send some simple pencil sketches and how-to’s on the method I
personally prefer. Blessing and Peace to all.
