Thanks, my first attempt on engeaving. Fiber laser cutting machine.
I've seen a smaller "laser engraver" machine at some trade shows. They typically market is as a hobby business opportunity to offer custom engraving on anything from leather, glass, metal, wood, plastic, etc. You can scan in or program any design and it will 'burn' it onto the surface. The unit I've seen is rather expensive for its fairly small size. But I don't know what you have Janis.
And don't forget the crack between the valve seats, apparently they all do that.Let the truth come out
I was so ashamed that did my head in same way, because of low budget.
