Here, Phil is cutting out a feather from a sheet of aluminum.
Now he's showing me how to file the edges of the aluminum to take off the rough stuff left by the saw blade.
You are now seeing Feather #1, all shiny... and Feather #2 which has been sanded though at this point still needs a lot more sanding with finer and finer grits of special sand paper. It take hours and hours of work to make these.
In this photo, you can just see the engraved spine of Feather #1. Feather #2 has been sanded and polished. It is now ready to have its spine engraved onto it, and #1 needs to have the spine engraved again as it has been partially polished off at this point.
Both feathers have been attached to my gas tank.
