Imagine you had a metal tube, with an oval cross-section…
approx. 1" x 1/2". Then say you wanted to pierce a pattern in
one side of this tube. A conventional jeweler’s saw is not the
answer. Obviously, I could pierce sheet and create the tube from
the sheet, but I already have the tube. Any ideas? I thought of a
separating disk, but I want to be able to do curves or more
Any suggestions appreciated, as usual!
