A long time lurker here. I have been enjoying the wide range of
subjects discussed and the replies to questions/comments.
I have a job that requires arranging three rings in as many ways as
possible. The rings are a man’s wedding band and a woman’s
engagement ring and wedding band. I have made sterling rings in
several arrangements so the customer can select what they like best.
The selected arrangement will be made up as a brooch. Some of the
combinations I want to do have proved impossible to hold in the
required position for soldering using the usual procedures.
Soldering investment would seem to be a solution. However, the
suppliers I buy from do not list soldering investment. I would
rather not try to use regular casting investment. McCreight (page
78. 3rd edition), with reference to soldering investment, alludes to
a “a similar product that does not harden and can be reused”. Any
on a supplier of traditional soldering investment, or
the name and source for the equivalent product that does not harden
and can be reused, would be very much appreciated.
