Самый глубокий лабиринт, экономия металла.

I'm working on a part that needs to be made from pipe, but I had to use rolled stock. To save on metal, I decided to try cutting out the middle section of the blank using a tool I call a labyrinth cutter. The blank is 112 mm long, and I need to cut 56 mm on each side, which is the deepest labyrinth I've ever cut.
