Here is a clip of the rotary engraving process I did on stripped lower. Only a clip cause the run time was almost 20 minutes. Typically I would use my laser engraver, but on this build I am going to be sending my lower off to WMD to have it nickel boron coated. So the long and the short of it is I need to have the engraving down into the surface of the aluminum. Should look pretty sweet when it is all finished.

This is a scrap of aluminum that I engraved and painted for effect. ....and the finished product. I'm curious to know what y'all think about this one.
