well, i finally gave it a try, it is ugly as sin, doesn't have a very good "lens" profile, and it isn't sharp but i sure had fun giving it a try. This is from a beer bottle bottom, leinenkugels sunset wheat to be exact.
i have a few questions to go with this:
i made my flaker from #6 grounding wire and it was very soft, i had to sharpen it very often, is this normal? would a sharp nail be better?
what do i need to do to get sharper edges?
now i need to drink another beer to get more material
