The most important thing you need to know before experimenting with
your microfold brake is that you should use metals 24 gauge or
thinner. There are exceptions, of course, but this is a good rule
in general, especially in a school situation. The corrugation gives
tremendous structural strength to those thin metals. I have a
brooch I made in 32 gauge sterling, for instance, that is
wonderfully light and strong.
There have been at least 3 projects in Lapidary Journal using the
brake. I did one that was published in the recent July issue, and
both Patricia McAleer (Trish - about 2 years ago) and Jack Berry
(about a year ago) have published projects in Lapidary Journal.
Trish and Jack have each published books on microfolding, and, to my
mind, you need both. After looking through them, you will have
LOTS of ideas to play with!
