Give it a try! My cutter has multiple settings. I use a slab mold, so I set it first to 3", then 1". It is always when I change the setting that the wire would break and winding and unwinding the wire around the key adds risk each time.
Good to know. So far, I'm on my fifth batch using the finishing lure, and that means that I have adjusted the line ten times (once to adjust it to 3" and once to adjust it to 1"). I've discovered that I do not have to tighten it extremely taut. So far, so good. I have a few spools of .0185 diameter fishing lure, which was not at all expensive.
