Do I have this right?
I never use cross hatch for inlay or overlaying golds or any other metal. I use single tooth for everything I do. In my opinion it holds tighter and will work in any situation. There are places in cavities where I find it impossible to crosshatch. I have learned to single tooth with the gravermach in rapid time. It works for me on silver and copper as well. But the efficiency of the teeth is related to the strength of the metal you are working on. I am not arguing against the cross hatch method. I just prefer single teeth.
