I'm glad someone asked that question. I assumed that everyone else understood what was going on and didn't want to expose my ignorance - - -Ok - curiosity has finally gotten the best of me. I've been following this post since yesterday. May I ask for what purpose do you scribe such a line on a transfer punch? Is there a helpful hint or something that I am missing? - Dave
I can relate to what you are trying. Have done this too. The method I described I use is something I also use when doing labels or covering a blank with vinyl. I lay the tube against the straight edge and score the material with a knife. Making sure I do not push too hard because easy to cut through thin brass. Then peel off excess and perfect straight line. Good luck and hope to see some cool blanks. I have one that I hope I can pull off with some material that has never been used here before. Be getting back to pen turning this winter hopefully.Thought about teasing out an answer over time, but don't want to be cruel.
Bending some metal to make blanks that will be clear cast, and I want the resulting pieces to be straight.
